3D imaging for whom?

Who needs 3D imaging? Is it useful at all in normal searches?

And yes and no… The reason is simple, it is quite a hindrance, which requires some knowledge and imposes a work regime. First of all, we need to properly configure the data logger and metal detector set, and not everyone is suitable for this. It is best to have the device working in static mode with VCO modulation. What does it mean? The tone changes – intensifies and weakens over the target, something like the so-called tracking function. Pinpoint in a dynamic detector. There is also the connection – wiring and signal calibration.

A good device is an equipment working as a PI or pulse induction – pulse detector. The advantage is the performance and stable operation on difficult ground, and the disadvantage is the lack of discrimination. It should be remembered that the imaging will concern rather larger objects. It depends on the probe, of course, but drawing the shapes of coins is rather pointless. We are interested in larger objects and such devices indicate this. The upside is that it’s the little bits that are omitted. It can be safely assumed that the 2×2 meter frame probe signals well objects the size of a can or larger.

The shape, approximate size, and depth are really good information. In an urbanized area, working with this type of device is more difficult due to evidence of human presence and infrastructure, such as pipes or wires. The advantage is also the visualization of empty spaces, such as basements, cavities, etc. A great solution for non-invasive research, site checking, and for commercial documentation of sites.

Currently produced devices, such as the GDI Icon 3D data logger we offer, are a fully wireless solution, for which a simple tablet based on the Android system is enough. If such a set is compared even with the finished Nokta Makro Invenio PRO product, it is 1/3 of the price and we have the option of choosing a detector with which the data logger works and thus slightly better performance, although at the cost of lack of discrimination.

In the end, there is the work regime, after the settings related to the type of detector and probe, select the sweep pattern. The software gives voice messages, and we follow the commands, i.e. we move at a certain time over a certain distance. It is worth marking the route with tape or plastic markers.

In the end, it remains to analyze the data in the form of a 3D chart and enjoy the results of our work!

DeepTech Vista Gold Hound PREMIERE!

DeepTech Vista Gold Hound is actually a good and proven old school analog in the world of metal detectors. There is no finesse or materials straight from outer space here. Everything is average enough…but not the performance!

YouTube player

The efficient 30 kHz operating frequency allows you to work in slightly more demanding terrain and with very small objects. Are you looking for thin hammered silver coins or fine gold? You will find them. You won’t miss the signal and you’ll appreciate the advantage of the old solutions, where you go only by ear, and every colorful object is checked by digging. This is not the era of displays and conventional ID indications, where the desired coin and can are hidden under the same number!

YouTube player

You have to put some heart and strength into the shovel and we get results. You won’t miss anything, no chance. Another plus is the fabulously simple operation. Good headphones and on the road where only two tones accompany you. Yes, it’s a minimalist detector. You can turn down the low tone of the iron, but it’s worth hearing what’s going on under the probe and whether we’re in the right placeu.

The manufacturer DeepTech leaves us one more powerful weapon, TRESHOLD. Without reducing the sensitivity, we regulate the ground response. We want a quiet and easier work turn. We crave signals from ghosts and deep-seated objects? To the right. The perfect solution for passing places.

Many years ago, the boys made a video with the model GOLD. It beat all other equipment available at the time and there was a wave of hate that the test was being set up. He was not. We know it. You can make it yourself.

YouTube player

Is this a metal detector for everyone and for beginners? Yes, but not for every place. It will do great in a total dump, it is very sensitive, fast as hell and deep enough and unfortunately will not allow you to compromise. No lazy searching here. You don’t have time to check, risk missing the prizes and buy yourself equipment with a TV set!

Nokta Makro The LEGEND kompletne zaskoczenie!

The Nokta Makro The LEGEND metal detector surprised me completely. I did not assume that the device is so well made and works stably and pleasantly. It’s too early to make a final judgment, but my buddies feel the same way. The device has potential.

Let’s start from the beginning. The premise of Nokta Makro was to take over a specific segment occupied by the Equinox 800 model from the Australian company Minelab … and I have a st

range feeling that it just succeeded!

In addition to the lack of defects, the quality and price known from the competition are impressive. We get real multi-frequency equipment, easy to use, waterproof, and really well made. A carbon Seatpost or really great quality wireless headphones with an additional case are really nice gestures and the fact that someone up there is listening to us. There are also disadvantages, such as sloppy glued shipping film, or keys without backlighting or coloring of function icon

s for better visibility. I’m probably picky, but I like complete solutions.

Weight and ergonomics are known from the cheap SIMPLEX+ model and this cannot be questioned, but let’s not forget. This is definitely a high-end detector! Why? The technology allows better signaling of low and high conductors, similar to fine gold jewelry. We will skip less. Work in salt water and highly mineralized soil? No problem. It’s a bit of a Swiss Army Knife, and it’s really refined. Of course, it’s not XP DEUS II, but I think that Minelab will start counting losses at this price quite soon.

The menu is simple and clear, but the settings are really amazing! Do you want to change the volume of signaling for a given ID, its tone, or range? No problem. Do you want to connect BlueTooth wireless headphones and not necessarily factory ones? No problem.

Okay, we already know that. The competition is similar. That’s a fact, but not at this price!

The Ferro Check function is nothing more than a bar showing to what extent the object under the probe is moving towards iron or color. It really makes work easier (caps and other junk), and if we add to it new polyphonic audio, a kind of multitone to choose from, we know much more. Purists can work in two or more tones, freely adjusting them. In the end, we save the ready settings after the pain. The lead signal doesn’t suit us? That’s not a problem either.

Flashlight, the vibration we know it. free update? Great nice too. Watch? Time is important, if the wife is waiting at home, it’s ok. Hour meter? Revelation. Now we know how much our detector really worked.

We have 4 programs such as PARK, POLE, BEACH, and GOLD FIELD. We have a depth indicator, we set the speed of separation of objects, the so-called recovery speed which also affects the depth. We automatically detune interference or select single operating frequencies: 4, 10, 15, 20, and 40 kHz.

I am very pleased with the choice of the MULTI work variant. The PARK and POLE programs, it is M1 and M2. M1 is a multi-frequency range sensitive to high conductors like silver, and M2 to low conductors like gold. This is a great move on the part of the manufacturer, allowing for precise adjustment to the prevailing conditions. The BEACH program has variants Mw and Md, where W (wet) means a wet beach and D (dry) a dry one.

The tests are ongoing. I hope you will share your opinion under this post, more information can be found in the video below:

Tarsacci MDT 8000 how to set up?

How to set up the Tarsacci MDT 8000 detector correctly? The device has a clear and simple menu, without any hidden functions, but still requires a lot of time to take advantage of the new technology, which is not used by any other manufacturer.

The first and key choice is the operating frequency of our detector. We choose from 6.4 to 18 kHz. Interestingly, even a low frequency allows us to detect very small objects in size … well, the charm of PI (pulse induction) used in this hybrid. Lower frequency means better performance – depth, but also worse separation of objects in cluttered terrain. It is also better for signaling coin-shaped and volume objects, as opposed to foil or pieces of aluminum.

Another workflow problem. We have three types: all metal, discrimination, and mixed mode. All Metal will be good for virgin spots, where the signal appears from the holidays. We only have one and we have to look at the ID displayed on the screen. DISC is the only right solution for total trash. The signal is short and if it is repetitive you have to dig. The mixed mode gives us additional information about the size and depth of the object. Places clean or moderately littered.

Before we start, we look for a clean place and calibrate to the ground, if we still have a signal from the ground, we increase the value by 50, this should mute the device. Next, we hear the response of the ground. We can try to use the SALT function – salinity level. We pump the probe traditionally above the soil and adjust the value to mute the response. The starting point is 29. Finally, we are left with THRESHOLD – TRH. You have to be careful here. Too high a value and we lose ranges and we will not hear small objects. We always set the limit. If the ID shows low values when sweeping the probe, we need to compensate with this function.

Iron breaking through the scale and falling into color can be handled by using a DISC value of -29 or +26. Finally, there is the sensitivity adjustment. It’s not worth exaggerating. MDT 8000 already at a value of 4 is deeper than most known detectors. We eliminate all instabilities and interferences by reducing the sensitivity or changing the frequency.

I am curious about your opinions on the Tarsacci MDT 8000 detector, write under this post.

XP DEUS II program GENERAL

The GENERAL program is the basic solution for the XP DEUS II detector. A starting point from which to start, but also a good base for learning and later modifications for your needs.

There are no universal solutions and if someone believes something like that, they are simply naive. Just like ready-made programs for anything and everything. We always start by choosing a program tailored to the subject of the search. For the multi-frequency version, we are looking at the frequency range. Their range will tell us whether the object of our interest will like them. Low conductors like gold love high frequencies, and silver the opposite. This is our primary indicator. Very difficult conditions and tons of iron, maybe it’s worth trying on a single frequency with the DEUS MONO program?

We return to the basic program. We start with setting the REACTIVITY, the most important parameter that affects the performance of the device, such as depth and separation of objects placed next to each other. A higher value and the detector becomes shallower, but it separates objects better, lower and we have a greater depth, but we have to sweep slower and we may not hear a coin placed next to iron, e.g. a nail. So how to choose the settings? We check what is happening under the probe and make a decision. We can experiment with different settings and see how it affects signaling and ranges.

The next step is the GB tab and selecting the GROUND STABILIZER function, a type of filter that affects the response of the substrate. The default value is 2, which is a medium mute level. At level 1, you can walk with some experience. The detector becomes less stable, but a little more can be heard. The end of the scale is a value of 3, the perfect compromise for soils that have a lot to say and make our lives miserable in the form of disturbances. We return to the filter called SILENCER, another compromise between performance and comfort of work, allowing us to eliminate crackling caused by iron elements in the substrate. A high value causes less interference, a lower value ensures that we can hear more again.

We are left with the choice of the type of audio. PWM or SQUARE is a personal preference. We have to answer the question of how much of an orthodox Deusiarz (PWM) or Minelab lover (SQUARE) we have in us. Sensitivity settings or calibration to the soil in a given place probably do not need to be explained, we still have audio and the choice of the number of tones. It depends on the place and personal preferences – your hearing.

The rest is hard training and a lot of work is put into settings and understanding. Without it, there is no chance of results. If you have any questions, comment directly under the video.

Clash of the Titans

The recent debut of XP DEUS II gave me a lot to think about. You can still feel the legacy of Whites Spectra in such an edition that it should be praised. The French company coped with this challenge quite well. Everything else is well known to us and things like wireless or featherweight no longer shock us. The novelty is water resistance up to 20 meters, which opens up completely new possibilities.

How does the TARSACCI MDT 8000 fare against this background? Many people would like to know what is the difference. The build quality and carbon fiber used put it truly in a class of its own, but the DEUS II leads the way here by the full length. It’s good, but as we know, everyone is one step behind and it’s been like this for many years. The weight of 1300 grams is currently the standard in the class of professional devices. Technically, however, we live in two different worlds. DEUS II is a multi-frequency metal detector, while MDT 8000 is a hybrid of VLF and PI (pulse induction) technologies.

So what is the advantage of such a solution? The technology is pioneering and patented in the USA and Europe, but does it really give you something more to spend your last pennies on this detector?

Just carry out a simple test and everything becomes clear. TARSACCI allows you to maintain a stable and unchanging ID in the close presence of small pieces of foil, magnetic stones, or high salinity or high mineralization. This advantage makes the device more resistant to masking. It will cope with more difficult conditions without changing the reading due to the presence of the above-mentioned disturbances and without limiting the depth.

A simple test gives the answer. By sweeping a piece of foil the size of a coin and a coin 5-10 cm above it just in front of the TARSACCI probe we have a fixed and non-changing ID. The foil does not change our signal, similarly, coke and rocks, and iron do not have such a big impact. For the sake of accuracy, we are talking about coin-sized items here. The same test in the case of DEUS II already gives a significant drop in ID.

The advantage of the last XP is multi-frequency, which allows the signaling of equally clear objects from both ends of the scale. Even for low and high conductors. Fine gold as well as heavy silver. The performance may be slightly worse, but in the case of one frequency, it will be slightly better. We have to answer the question what are we interested in? Good signaling of various objects or less masking effect in very difficult conditions? It all depends on the place and subject of the search.

Both models of detectors have the ability to fine-tune settings. DEUS II has more possibilities, and the MDT 8000 is simplified to such an extent that for professional equipment from the top shelf, it is simply strange. The producer decided to put everything on one screen. There are no drop-down submenus like in XP. We see everything at a glance and we don’t have to check if one of the many filters is definitely well-selected and does not affect our performance.

In conclusion, the race is fierce and it is difficult to pick a winner and compare both detectors directly. TARSACCI is more of a Swiss army knife, equipment for heavy and complicated scenarios, where high mineralization or salinity requires the use of a heavy caliber. DEUS II is a versatile, fun metal detector that is lightweight and waterproof, with great configurability and wireless connectivity to make your life easier.

XP DEUS II program RELIC and IAR

The new XP DEUS II surprises. I mean this seriously because over the last few years my DEUS I has been dusting a bit in the closet. As you can see, the French have drawn conclusions and decided to change a lot for the better. The new audio does the job. It does not tire, it is soft and pleasant. This is important because the detector should give joy, not fatigue. This is often the last bastion of freedom for many of us. Our couple of hours on the weekend, separated from reality in nature.

IAR (Iron Amplitude Rejection) discrimination and the RELIC program I decided to test on a well-known field with high mineralization and high iron content. First, run and I can’t hear the audio. Nervous situation. Restarts the hardware. In this place, all the equipment sounds beautiful … but not the new DEUS II. It is so stable that I was fooled like a child by a supposedly non-working loudspeaker … For the first 20 minutes, both Mariusz and I are completely surprised. No, we don’t find anything, but that’s not the point. The detector signals target only. Audio flows and multi-technology stabilize the rough ground. How about the performance? Too early to judge.

To make it better, it is All metal and you can also hear iron, although factory muted. The time for real tests will come in the season. Playing at temperatures below zero degrees Celsius is a bit masochistic, but it was worth it. Remember to subscribe and we’ll meet soon.

Professional detectors for deep excavations

Deposits, relics, or treasures keep many people awake at night. This is every Seeker’s dream. Get something like this. It is not given to everyone.

Deep burials are now rare. It’s not an easy topic. The case is complicated and complex. So what to use for a large animal? Lots of people have heard of it but don’t know it. Frame detector, impulse detector, then there are the terms data logger or graphic imaging.

INVENIO device

The choice is wide and the prices can make you dizzy. From the Nokta Makro offer, you can choose the best INVENIO metal detector. The device in a simple and easy way perfectly illustrates buried items, although it requires attention and a certain work regime. Unfortunately, it is not available to everyone. The price of PLN 35,000 means that it remains in the realm of dreams. It must be remembered that this type of equipment is a poor choice for everyday searches. In addition to the knowledge put in, the solution needs time to interpret the data – to process it. It will be more suitable for archaeological research, field measurements, or when looking for specific things.

Impulse detectors

So what to go with a big animal? I recommend a pulse detector. frame and preferably with a magnetometer. I know from experience that for large militaria the size of the probe is 1 x 1 meter or more. Smaller solutions are too sensitive to small objects and this causes various problems in the field.

In our offer, you will find DeepTech Ground Pioneer 4500. The item is interesting because you can order any frame size in the set and you get an 11-inch probe plus a frame. You can look for small items in the uncluttered areas, such as coins, and this is a big help. If it is clean, the performance will be higher than in classic detectors with VLF technology. PI pulse devices do not have discrimination. The magnetometer helps in the rough differentiation of the so-called color of iron. This is a very helpful solution.

Ciekawostką w ofercie jest sonda do sprawdzania szybów wentylacyjnych czy studni. Można ją zamówić oddzielnie, podobnie jak data logger, który pomaga nam w obrazowaniu znalezisk.

Operation of the detectors

Finally, let’s talk about performance. A beverage can is up to 2 meters deep with a frame size of 1 x 1 meter. In the case of a vehicle, you can talk about performance up to 8 meters. No need to worry, we won’t forget the tank. Objects below the size of a can are not detected, which in the case of surface debris – small can help us.

An additional advantage is an ability to work in the case of a highly mineralized substrate. The disadvantage of this type of device is the speed of operation, lack of discrimination or the need for assistance when using. Two people should carry the probe, and the third one operates the control panel, if we add a data logger to this, the whole thing requires patience, coordination, and an understanding of the operating principles.

So who should choose such a device? Seekers, Deposit Hunters, this type of offer is addressed to them. Archaeologists or geologists document places and also search for empty spaces. As you can see, the application possibilities are quite wide.

DeepTech metal detector – heir to Tesoro

The Tesoro metal detector was synonymous with durability and quality, simplicity, and outstanding performance. Unfortunately, like Whites Electronics, it was lost in the depths of history. It won’t come back anymore. DeepTech used the legacy of Tesoro, adding a lot from themselves, and while you can have reservations about the quality of workmanship, absolutely not when it comes to performance and audio.

Analog devices

The simplicity of analog knobs and two-tone audio does not appeal to every Seeker or Detector. You have to be born with it or love it. There are no bells and whistles, you will not see the display and numerical identification of the target. Ground calibration is manual. In this way, we get to know the roots of detecting, and the adventure with the metal detector becomes complete. We learn the equipment and the principle of operation, we understand many factors that we normally miss.

Such analog organicity in the world of metal detectors. The lack of a scale of numbers forces us to constantly work, it is more difficult to skip items because you have to check it. Our hearing becomes our ally in the search, and not the board in the detector housing, but our brain becomes the computer. There is a no faster and better computer.

I remember Mariusz and I were surprise when, testing the 14-inch probe for the Vista X detector, we buried Kopeyka at 67 cm in an arable field. We couldn’t believe that the device would signal it. We checked a couple of times. We had doubts about whether something had been overlooked us. Next was a 47 cm thin silver coin, similarly loud and clear. The last was the base of the IWW fuse, a trifle 1 meter 20 centimeters long. There are no illusions.

On top of everything comes double discrimination, which allows you not to lose off-road performance. The most important depth. Other metal detectors don’t have that choice. We set discriminate and lose performance. Here we can check items. In the DeepTech Vista X model, there is also the so-called. Threshold, i.e. adjustment of the threshold signal, in this case, it is rather a ground filter, allowing for smooth regulation of its response. We want to work silently, without ghost signals or interference, we just turn and kick certain signals only. We want to reach deep, we dial the threshold and look for ghost signals. We only dig the silent deepest targets.

 

Alternative to SMART PRO+

Anyone who appreciates simplicity can choose the SMART PRO+ model. Why? It does not have double discrimination or Threshold, but it has a Pinpoint with which we can precisely target targets and, with a little practice, check their type. A simple and intuitive device, which, according to the manufacturer’s assurances, is not inferior to the Vista X model.

Summary

Finally, there’s the Vista Gold Gain II metal detector. The high frequency of operation allows searching in heavier soil conditions and with greater iron contamination and highlights small and thin objects. Gold jewelry or silver coins are no longer a problem.

Everyone will find something for themselves and that’s for sure. If you want to focus on the results and not on the equipment, take a chance and choose DeepTech.

The best Tarsacci MDT 8000 detector revolution in the user’s eye

Half a year ago, if someone had told me that I would get a professional detector like the Tarsacci MDT 8000, I would not have believed it at all … and I did not believe it waiting for a device straight from the USA. I had my doubts standing in the field with him. Now I’m sure. This is the best device I’ve had in my hands for over 10 years … unfortunately, not the cheapest either.

Pros and cons of the detector

I understand there will be two camps here. One says that a good thing must cost money and the other is where you can buy really great equipment for 1/2 the price. Both sides have their reasons, but as we know, the devil is in the details.

Quality workmanship knocks down. No slack, fudge, or complaints … there is one defect of the carbon detector post … apparently, it whistles in the wind … that’s what I read on the Tarsacci forum on Facebook.

Tarsacci Poland:

https://www.facebook.com/groups/363009768484651

Tarsacci UK:

https://www.facebook.com/groups/795633577904679

Everything else is a masterpiece, but it doesn’t surprise me at all. Just check who is responsible for creating this equipment. Dimitar Gargov – former engineer of the Fisher Labs company, which needs no introduction to anyone, like their metal detectors, which are known all over the world. Finally, just add the name and surname: Thomas Dankowski and we have one of the best duos in this field in the world. After over two years of testing and we have the Tarsacci MDT 8000.

Water resistance is a big advantage, but to surprise nowadays, apart from performance, you have to give something else. In this case, we get amazing, soft audio that was created by someone who really dealt with real field research. The sounds do not tire for many hours, they give a precise description of the item and a lot of additional information. When we add above-average performance even with the first 11×9-inch probe, we are shocked. There’s no need to cheat. The Polish icon RUTUS Alter 71 is over 7 to 10 cm shallower in mixed mode, which can be seen in the videos below.

A quick visual comparison of Tarsacci MDT 800 and Rutus Alter 71 in heavy clay soil.

The joy of a professional detector

The popular Boratynka with 30 cm? No problem. Loud and clear, not to be missed. The machine confidently fastens on good objects and gives a descriptive response in the form of sound. Trash and the signature changes, and the sound is longer and blurry. There is no doubt. Here’s an example search video. For several weeks, Mariusz has been unable to get rid of the feeling that he should collect money for this detector. Unfortunately, it is financially out of his reach.

How often to search for metals

In the end, a knockout in a littered area or under the lines. Work stability. There is complete silence. Sometimes I check with a shovel if Tarsacci is still working. Do you have a problem? Is something waking up? You change the operating frequency for your choice: 6.4Khz, 9Khz, 12Khz, and 18Khz. In this way, you can influence the performance or adjust the frequency of work to the prevailing conditions or the items you are looking for. For example, we are interested in big and deep old iron, we use 6.4Khz. We need to take care of ourselves in the trash and look for something small 12 or 18Khz will be a great choice.

The manufacturer spoils us by giving a huge Li-ion battery in the set and a charger, basically two batteries with a capacity of 5000 mAh each. I don’t remember, yet, that it was possible to completely discharge it by going to 9Khz. After 4-5 hours, no line falls, and we still have a supply.

Intuitive operation of the Tarsacci device

The simplicity of use brings to mind devices from the lowest price segment. No drop-down menus or hidden functions or filters that we need to remember about. It’s an amazing advantage. We don’t stand around and rummage through equipment while others dig up stuff.

Flexibility to work in various conditions, from extremely salty beaches to highly mineralized soils, puts Tarsacci at the forefront of the best devices of this type. We have the ability to compensate for volcanic sands and magnetic soils in the form of the BLK (Black Sand) function. We also affect the salinity with the ST settings. And I don’t mean an ocean beach at all… but fields with tons of fertilizers. In this way, apart from the stability mentioned at the beginning, we get peace of mind in the form of no masking from coke or foil. This is a significant advantage over other devices that simply can’t cope in the world.

You can go back to the places you have been to and enjoy them again. In combination with the new 12-inch probe, we get another up to 10 cm more. Finally, the user’s statement:

☘️ Half a year with Tersacci and 2 months with a 12 “coil. I have flown a lot of hours, I think I used 10 batteries and one is enough for a very long time 18 hours at 6.4khz and over 30 at 18khz. There are rather no defects in the construction, the only holes in the seat post howl in the wind ? but they are already wrapped. The traces of wear on the machine are negligible. As for the new coil and without the cover, it seemed to me that it would wear out very quickly, but nothing could be more wrong, only minor scratches came out and that’s it, and the areas were plowed fields, meadows, and stones.

As for the handling, it is very strange because I have not yet met a detector that would be at maximum sensitivity all the time and was so stable ..! As with all detectors, you have to overlap and dig to understand what and where.

Anyone who has doubts and decides that it is just marketing can use the forum where users describe their experiences with this detector in English:

https://www.dankowskidetectors.com/discussions/read.php?2,152652

See you in the field!

An invention that saved many lives

The hand-held mine detector – because that’s what we’re talking about – was invented by Józef Kosacki in 1941. The prototype was built in just three months, and then quickly went into serial production to “significantly contribute to the Allies winning World War II”.

Even King George VI sent a congratulatory letter to Kosacki in recognition of his merits, and yet few people know about the Polish inventor today. Just like the circumstances of the creation of the prototype.

And it all started with a tragedy. On June 1, 1941, a team of several people from the then-famous 10th Armored Cavalry Brigade was sent to comb the Scottish beach near Arbroath. A routine patrol hit the coast, which, however, had been mined before the British – for fear of German landings. But no one knew about the mines. None of the Polish soldiers returned from the mission, which shocked both British and Polish commanders. One of them was Lieutenant Józef Kosacki, who quickly decided to return to the idea he had been working on in pre-war Poland.

The starting point for Kosacki was the discovery that telegraph amplifiers react with hum to the presence of metal. That is why he used this phenomenon by constructing a mine detector – he worked on the prototype for only three months, using the phenomenon of the electromagnetic field.

What did his detector look like?

“It was light, weighed about 14 kg, and at the same time relatively simple, possible to be carried and used by one soldier” – remind Teresa Kowalik and Przemysław Słowiński in the book “Royal gift. What Poland and Poles gave to the world”. It consisted of a wooden satchel with an acoustic frequency oscillator, an amplifier, and power batteries – put on the back. And also from a bamboo stick with coils and a variometer (it’s nothing more than an inductance changer). Small, uncomplicated, and handy (“earlier devices were not suitable for use on the battlefield. They could help engineering services clearing a battlefield, but not soldiers breaking through a minefield”). And most importantly: very effective.

A handful of 1p coins were scattered on the beach. The task was to find them all. The competition, which was announced by the British Ministry just a few days after the tragic events near Arbroath, had 7 applicants. The winner turned out to be Kosacki – his detector tracked all the coins. Very quickly, thus outclassing the competition.

The device received the official name “Mine Detector, Polish Type No. 1” and quickly went into serial production. Then it entered the equipment of the British army, and over time it was used by other allied armies. The detector was used for the first time in the Second Battle of El Alamein in 1942, where it significantly contributed to the Allied victory.

“In the following years, improved and modified, the mine detector found its way to battlefields around the world. Simple, yet effective, it turned out to be extremely long-lived equipment – it was used until the 1990s, of course in a modified version. The number of people saved by it can be estimated in thousands.” That is why today Kosacki is most often referred to as “the man who contributed to winning World War II”. Or shorter: “Pole who stopped death”.

Metal detector for beginners

Searching for coins, souvenirs and various types of treasures hidden underground is an activity that has many enthusiasts. Every person who wants to start their adventure with treasure hunting should equip themselves with a decent metal detector. What model will be ideal for beginners? We have some tips. We encourage you to read!

Which detector to choose for the beginning?

The choice of metal detectors is very large. There are devices with the logo of many manufacturers, with different parameters and in a wide price range. What issues should you pay attention to when looking for the perfect first detector? We have some tips!

What is our goal?

Question number one is about our goals, which is what we will be looking for. Depending on your preferences, we can focus on searching for coins, military items made of steel, jewelry, items made of non-ferrous metals, and many other valuables. If we want to focus on specific items or do not intend to waste time digging up worthless garbage, a device with a discrimination function will be an excellent choice. And matched to the artifacts we are looking for – objects.

Where will we look for valuables?

Another important issue is the areas of our search. Let’s analyze whether we want to focus on forests, meadows, beaches, and other places of this type, or whether we plan to walk with our device through a river, and ponds, and wander in the waters of seas and lakes.

Metal detector – price

Of course, the purchase of a detector is a cost and often it is not small money. It is good to determine at the outset how much we want and can pay for the device. However, it should be remembered that devices from the lowest shelf, for about PLN 150-200, may not work well and disappoint us or even discourage us from the hobby. The optimal solution for beginners is to buy a mid-range device for about PLN 1000-2500.

Metal detector – working time

The longer the expeditions, the more capacity the device should have. Keep in mind, however, that the weight of the device increases with the capacity of the battery. For beginners, heavy models may not be a very comfortable solution.

Metal detector – technology

For beginners, detectors that are easy to use and have basic functions will work best. Professional equipment is worth buying when you gain experience.

Detectors for beginners – a few suggestions

Metal detector – which one to choose?

Jaki wykrywacz do metalu wybrać?

Treasure hunting – coins, jewelry, and other valuable items is an interesting hobby that is becoming more and more popular. Of course, in order to start your adventure, you must first equip yourself with a decent metal detector. What issues should you pay attention to when choosing the perfect device? Below are some tips. We encourage you to read!

Metal detector – what to pay attention to?

People who want to start their adventure by searching for coins, jewelry, historical memorabilia, and other valuable items can choose from VLF dynamic detectors, pulse detectors, and IB detectors from many manufacturers and in a wide price range.

What parameters, in particular, are worth paying attention to so that the selected model is 100% suited to our needs? The most important parameters here are:

Operating mode – one of the most important parameters to pay attention to is the detector’s operating mode, there are static and dynamic devices available.

What are the differences between them?

Static mode – when the probe approaches a metal object, the detector reacts by changing the sound intensity. The detector beeps as long as the object is in range of the device, and stops when neutral. By changing the modulation of the audio signal, it is possible to determine some of the characteristics of a metal object.

Dynamic mode – the detector responds with a change in sound intensity when a metal object is nearby. Unlike devices operating in static mode, it goes silent when the person operating the detector stops.
Resetting function – changing the detector’s settings may occur as a result of temporal or thermal instability, here the resetting function is extremely useful, which allows you to efficiently (just press the appropriate button) return to the previously set detector functions. Static device domain.

Discrimination mode – it should be noted that not all metal objects found in the ground are important for seekers – we are talking about cans or foil, for example. Instead of wasting time digging up and cleaning useless items, it is worth focusing only on those that are important to us. This is why detectors with discrimination mode are the recommended solution. Discrimination is the device’s ability to identify buried objects based on their conductivity and ferromagnetic properties. Advanced detectors are equipped with 5 discrimination modes, they are:

discrimination disabled, all metal objects are signaled with one tone, so-called all-metal

the device does not detect ferrous objects – silent discrimination (they are omitted in the audio line)

in the case of detecting ferrous objects, the detector signals them with a low tone, in the case of other objects, the tone is high

discrimination of selected non-ferrous metals – the selective setting of signaling depending on the conductivity scale (numerical ID scale)

tonal signaling of all conductors – the so-called Multitone. Each conductor has a different signal, often the ID scale is up to 99

Probe – coil detects electromagnetic waves that are sent to the ground and receives electromagnetic waves induced in the object.

DD or CC probe. We have a choice of coaxial or DD probes, each has its advantages and disadvantages.

Shaft – has a significant impact on the weight of the device as well as its compactness and ergonomics. The peak of dreams is a carbon fiber telescopic version.

Ground balance – every treasure hunter should be aware that there may be small iron particles, salts, or other minerals in the ground that will cause the detector to react. The ground balancing function ensures that we only hear signals from an object buried in the ground, and the sound is not affected by the ground response. We can list three modes of ground tuning, these are manual, automatic, ground tracking, and so-called tracking.

Power supply – another factor that we must pay attention to is the power supply of the device. Remember that not only the capacity of the battery or power cells counts but also their weight – the lighter, the less tiring the hikes will be.

Detector weight – heavy detectors are simply inconvenient and impractical. It is therefore worth betting on a model that will be durable and at the same time relatively light.

Range – the range of the detector depends on the size of the underground object. In the case of a button or coin, the range can be even 10-25 centimeters and more, in the case of a larger medium-sized object 50-80 cm, and in the case of large objects about 1.5 m.

Metal detector – other parameters
In addition to the above-mentioned features, it is worth paying attention to such issues as a loudspeaker that will guarantee the high signal quality, an adjustable armrest that will increase comfort while searching, an intuitive interface with which you can adjust the volume and discrimination, and set other key functions.

Summary
Searching for hidden objects in the ground is an exciting hobby that is becoming more and more popular. On a great treasure hunt, of course, a metal detector is essential. What parameters should you pay attention to when choosing the perfect model? Here you can list issues such as operating mode, discrimination mode, operating frequency, probe size, iron masking, frame, ground balance, power supply, weight, or range.
In case of problems with the choice, it is worth relying on the help of specialists who will carefully analyze our needs and propose the optimal solution.

Minelab Manticore or XP DEUS II?

XP DEUS II vs Minelab Manticore who will win this duel? It depends … it depends on what we expect from both detectors because both are really good.

DEUS II is the king of ergonomics when it comes to the lack of cables, weight – 960 grams, and compactness, and there has been no competition in this category for years. What else? The audio was created by a real musician. Also undefeated for years, although Minelab created more pleasant tones and less tiring, also worse describing the subject. What is the difference? On nuances and additional sounds and their change and their modulation and volume. A piece of aluminum in the form of a can sounds differently than a coin, even if it is similar in its conductivity. It’s a lot. After a while, we know what is what. That’s what it’s supposed to be about. Disadvantage? In the long run, such audio can cause fatigue, especially in areas littered or full of iron. This is a minor difference, but for an experienced user, it is crucial.

Do we know anything more? Yes. Thomas Dankowski from the USA is a well-known American device tester before releasing them to the market. Over 40 years of experience is indisputable and his contribution to the development of many well-known devices is crucial. He has been testing Minelab Manticore for over a year and on the Dankowski forum (link: https://www.dankowskidetectors.com/discussions/index.php) he shared his observations with us, comparing it to devices such as XP DEUS II and Tarsacci MDT 8000 which also tested.

The Minelab Manticore was tested on the coast and on the beach, the inland tests simply did not take place and according to Thomas, the new Minelab is a slightly worse separating detector than the XP DEUSA II. Calabash Digger drew similar conclusions in his tests, which can be seen on his YouTube channel.

One important observation has been mentioned, the Manticore will be slightly deeper and it’s a matter of an inch or so (2-3 cm). This means performance at the level of the Tarsacci MDT 8000, which is a PI/VLF hybrid device and this means that such equipment is always deeper.

The 2D visualization of the Minelab detector in a clear field allows you to analyze the target, something more than the well-known XY plot from DEUSA XP. Unfortunately, with a large amount of iron, it does not work so perfectly and can lead to disappointment. As we know, everything requires learning.

The thing to check is the color spoof issue with heavy condensation of rusty items, but that takes time and fieldwork. It should be remembered that new software updates can change a lot for both manufacturers.
