Nexus vs rest of the world

The race is on for the best, free flashlights, vibrations, water resistance, 50% more power, 2D, 3D, and 6D graphs … thousands of slogans and advertisements attack us from every side. What do we get in return?! Often the same thing just in a slightly different package. Do you know this feeling? In a good restaurant, the old proven pork chop served with mun mushrooms and mars fern moss looks like an exotic and unknown dish. After the first bite, reality returns…

In all this, Nexus Detectors seems like a relic of the past. Old, but well-made knob detectors remind us of the years that are behind us. Nothing could be more wrong, because inside there is electronics that is light years ahead of everything we know!!

Advertisement?! You’ll find out soon, some people will pick up their jaw from the floor or buy hemorrhoid ointment, such burning can’t be endured without anesthesia!!!

Ok, relax, the working time on ten batteries is not overwhelming, but you can always change them in the field, the weight, depending on the probe, is survivable, because the balance is great. Yes, it is not equipment for beginners, although they will master it with a little patience.

Why am I so excited like a pedophile in a toy store?! The reason is simple – a performance that other manufacturers can only dream of. Depth and stability of work are unattainable by any other device! I write this with full responsibility! There is a video at the end of this article that shows it all in detail, but it’s nothing compared to full EMI immunity and virtually no iron masking! No other device has such capabilities and it is not a minimal difference, it is a gap that the leading manufacturers have not been able to overcome for years and do not even come close to a meter.

What will we see in the movie? A very interesting test of a small coin close to the nail, so interesting that it cannot be repeated on any other device. The minted silver coin, however, is a low conductor and lies close to the iron on the conductivity axis, but is not masked by it!

Another test is a mass of aluminum tear-offs from cans and a coin also without a problem. Tests did not in the air but on the ground full of iron in the so-called. 3D configuration. Total shock, it looks like a completely impossible thing to do on another, even the latest metal detector!!! Yes, it’s a single operating frequency in addition.

Be sure to follow this blog regularly! We have such a detector and we are not afraid to use it! Price and availability? Only on request, and with these performances, the price is justified, which cannot be said about other manufacturers!

EMI interference

What is EMI Interference? The definition is quite broad and a bit confusing for non-technical people:

Electromagnetic Interference (EMI) is any signal or radiated into space or transmitted through power or signal lines that threaten the operation of radio navigation or other safety services, or seriously degrades, blocks, or repeatedly interrupts licensed radio communications. Radio communication services include, but are not limited to, television and radio broadcasting, mobile telephony services, radar scanning, air traffic control, paging services (pagers), and PCS (Personal Communication Services). Licensed radio services, such as those used in WLAN networks or Bluetooth technology, together with incidental transmitters, such as digital devices including computer systems, contribute to the electromagnetic environment.

In our case, these are simply interferences that make the work of the metal detector difficult or even impossible. Half the trouble is when the process is visible and the device characteristically excites, generating a target signal and a numerical ID. Then we know that we are dealing with them and can take appropriate measures. What? Detuning the so-called changing the channel, reducing the sensitivity, or choosing a different operating frequency, if possible, direct elimination of interference sources such as telephones, transmitters, electric fences for animals, etc.

In difficult cases, you can use discrimination and cut-out interference, but this is only a half-measure. We lose performance, which is already heavily limited by EMI interference. A colleague who accompanies us can effectively deprive us of the chance to find finds, being even several meters away with his detector! Don’t fall for the group search, it’s just a nice time at the rally, you can’t count on the effects in such conditions. It’s unlikely!

What was the better situation, and what is the worse? Quiet disturbances. The ones that are not visible, and everything seems to be ok. We lose performance, but the detector does not signal it in any way. You can put a coin under the probe and the device can be completely blind. How to defend against it? It depends on many different factors, and above all on the type of device we have.

We preventively check other programs and detune the device from time to time. We check the signals with the person next to us to see if our detector can handle them as well. It’s the only option. SMF-type machines – simply put, multi-frequency machines, usually work in two or more frequencies, processed by software. In some cases, it may turn out that what was supposed to be a great advantage of a wide frequency range becomes a disadvantage!

For example, we have a program working in the range from 5 to 40 kHz – ideal for searching for gold, i.e. a low conductor is allergic to high frequency, and silver – a high conductor to low frequency. In addition, high frequency copes with small things better and with greater mineralization of the ground. In the case of low frequency, objects with a larger volume are signaled better. Story. We will not miss anything from what interests us the most!

Unfortunately, right now our greatest enemy is approaching and eliminating one of our frequencies. Without seeing it, we lose 50% of the possibilities without knowing it. Often programming and filters sewn in with it additionally stabilize the work of the detector. For this reason, the prevention described above is important. In this way, we will avoid erroneous opinions about the equipment and unreliable tests, especially from the test tracks. Interference can confuse us, so it is worth spending many hours checking different variants of settings in the field in various conditions!

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.


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.
