Minelab Manticore and Multi IQ+ technology

The first outing with Minelab Manticore was not successful. I had considerable doubts. After all, the price is about 10 thousand. PLN does its job and we have above-average expectations. The detector frighteningly distorted the color and no change and raising the iron limits (FERROUS LIMITS), or lowering the sensitivity and ground calibration did anything. I was stuck. I tried various ways to deal with the change in reactivity and frequent detuning, but it did not bring the expected results. The device was unstable and it was difficult to figure out what was the correct signal from the target, and what was ground interference and color-distorting iron.

Yes, the place is very difficult, and not because of the soil, which is easy and sandy, but because of the amount of iron in it. Minelab Manticore requires a bit more knowledge and experience from the user than devices from the lower price range. Here you have to think hard about what program we will choose for the prevailing conditions and how we will set it. In my case, I decided to change the program from a FAST setting to LOW CONDUCTORS. So low guides. Why? Old and fine silver has a very low ID and is located right next to iron.

The next step was to determine the iron ranges (FERROUS LIMITS), here the matter is not so simple. Low value more color distortion but less masking. I decided to set the upper value for fine iron – such as nails – to 6. This is slightly less than factory 7. The extreme version is 4, but I do not recommend it at the beginning, maybe when you get used to the equipment. It gives amazing results.

Recovery speed is a parameter responsible for the separation. Here I stayed with factory 5, and sometimes I use 6 in a place with more traffic 😉 Higher value, better separation of objects and more stability, less range. At low values, you have to sweep slower and the equipment becomes less stable. Fortunately, we can influence this with the speed of the sweep. When we come across a garbage can – we slow down, and when it’s clean we can easily speed up. Patience and experience, humility, and there will be results!

It remains to set the sensitivity. The principle is always the same as in other detectors. We go up and watch how the detector behaves. Unstable work, we have to go down. Along the way, we do NOISE CANCEL, i.e. scanning channels to look for the best one. We can combine this with the sensitivity adjustment and choose the right setting. It is worth holding the interference reset button longer until you get one repeatable channel after each scan. In the case of Manitcor, the algorithm analyzes the interference and selects the best channel for the given operating frequencies selected with the program.

Audio. What audio to choose in a place where iron and its natural oxidation make even shallow objects practically inaudible?! I chose the ENHANCED option with noise reduction and it was a hit. Finally, the number of tones. It has been known for a long time that simple audio is the best in a dump or among the iron. One ton fell. Modulation? I chose SIMPLE, which is the smallest difference between a strong and a weak signal. Why? A large value for the MEDIUM or RICH parameter makes it easy to get lost with a large number of different signals, especially high tones from piercing iron. We want to check every signal and not miss anything!

Ground calibration remained at 0, although tracking did not introduce significant changes. The maximum corrected value is 2. The device cannot be manually adjusted by the pumping process here – too much iron!

Let’s go back to the results obtained, and this one completely knocked me off my feet! The spot I passed through revived and began to produce signals that were previously inaudible to other devices, and I spent almost two years in this place! It’s a strange feeling to pull stuff next to your pits and footprints … MultiIQ+ software Minelab does the job in combination with very fast hardware. The sensation is shocking when the detector separates the masked signals with the iron and the 2D graph becomes a checking tool. How to do it? The matter is simple because it is very easy to distinguish interference from iron and ground in the ENHANCED audio. In case of additional doubts, we look at the chart and rotate over the target by 90 degrees. In this case, after rotation, the TARGET TRACE signal in the conductivity axis, signaling the so-called color returns to iron. The chart gives us amazing opportunities to check the signal. For example, it shows large iron objects masking low conductors, small iron showing color, but also a pair of different objects next to each other. The dominant of the stronger signal changes with the change of position over the object. It’s just brilliant! If we add interference, mineralization, and different types of conductivity, we have a full picture of the possibilities!

Finally, is the detector worth 10,000? zloty? Certainly not in this country. We simply cannot afford it and no matter how good the ratio of our earnings to price is, it is unacceptable. Too bad no one talks about it!

The revolution that is not coming

I have a strange feeling that the world of metal detectors is stuck at a certain point. We have been waiting for spectacular changes for years and they are not coming… maybe they are coming differently, but on a different scale than we expected.

Minelab Manticore or XP DEUS II are really good devices, but do they bring anything groundbreaking apart from the dose of well-known solutions?

Certainly, SMF devices are better than what we know from the past, but they are also not without their flaws. The advantages include stable operation in more difficult conditions and better ID compared to single-frequency devices. More accurate signaling of objects from both ends of the scale – low and high conductors. This makes detection easier. This makes detection easier, e.g. old and fine silver is the beginning of the scale close to iron, while large is its other end in SMF, it works really well.

What disadvantages? Less resistance to EMI interference – after all, we work in a wider frequency range and slightly worse performance when it comes to depth.

In my case, I always choose an advantage in the form of better identification and separation in iron, and this can be different, opinions are divided here.

It must be remembered that such a Nexus MPV3 is completely immune to EMI interference, which makes it much deeper and, after adding the adaptive speed of separating the target, insurmountable … unfortunately, you have to pay for it and it is a device for conscious detectorists. It is not light and consumes 10 AA batteries in a short time. Something for something as they say.

We also have the Tarsacci MDT 8000 with hybrid PI and VLF technology. A mix of pulse device performance and VLF discrimination. The detector is really deep and works great in iron or with magnetic stones. Unfortunately, target signaling and its interpretation is no more difficult than in VLF and SMF devices.

It’s better, multi-frequency detectors are more stable. Such a good old Whites Spectra, using three frequencies, is much shallower and very susceptible to interference. It will not separate as well, especially in iron. In addition, under high-voltage lines, there is no chance and nothing will change it, no change of settings.

It remains to wait and watch what the next years will bring, I know that it will be interesting, that’s for sure.

Nokta Makro The Legend real SMF

The Collins Dictionary defines the word “legend” as follows: When you refer to someone as a legend, it means that they are very famous and admired by many people. That’s a definition that certainly includes the Nokta metal detector – it means both famous and universally admired.

There are multi-frequency (MF) detectors and there are simultaneous multi-frequency (SMF) detectors. Both have their followers, so which is best? It depends entirely on where you regularly look and how you look, not forgetting other aspects of fun. These will include consideration of after-sales support, accessories such as probes, warranty repairs, and even dealer reputation.

MF detectors offer operators a range of frequencies from 4kHz to 81kHz, depending on make and model. What MFs don’t do is generate multiple frequencies at once, unlike SMF. Because MFs transmit one selected frequency at a time, their electronic target analysis systems are less complex and therefore less expensive to manufacture. This is usually reflected in their much lower price. Many seasoned MF aficionados prefer to tune their detectors to the frequency that best suits the type of target they are looking for… eg gold, minted silver, copper, and even iron objects.

Nokta Legend is a real SMF that transmits 4kHz, 10kHz, 15kHz, 20kHz, and 40kHz synchronously. Why? Straight. SMF is a catch-all system. Lower frequencies penetrate deeper into the ground/wet sand, while higher frequencies – although slightly less so – are more sensitive to small gold objects. A single MF frequency option is also available to the user.

At a price of around PLN 3,835 along with “promotional offers” that include additional probes and other accessories, it is hardly surprising that the Legend is so highly regarded. Don’t be fooled, this is a technologically advanced detector with features usually only available on the market for detectors worth over PLN 7,000. What makes it stand out is that it has an average price.

From a commercial point of view, it’s a damn strong mix. Nokta placed the Legend electronics in the same housing as the Simplex+ model. The build quality and architecture are typical of a Turkish manufacturer. The model is solid and based on the experience gained in the production of other detectors. As sailors say about yachts: “If it looks good, it will sail well.”

Where we have garbage and iron, a small probe should be used, and anyone who searches the shoreline knows what I’m talking about. Beach seekers often avoid cluttered areas like the plague. Other tough guys work in these conditions, pushing the capabilities of their devices to the limit.

Large-diameter probes are not my ideal choice in cluttered areas, due to one major disadvantage: vulnerability to “target masking”. In the case where we have two objects – one garbage and the other, e.g. a gold ring – both entering the field of work, and the garbage object is often the stronger signal of the two and “masks” gold. Some areas were not only loaded to the brim with garbage and all sorts of metal objects but also lost jewelry. Not surprisingly, these places are almost impossible to search with large-diameter probes, and I mean the 11-inch Legend probe as well. As you might expect, many Seekers steer clear of littered areas. The key to unlocking the loot is a probe with a small diameter of no more than six inches. The likelihood of two targets falling into the small diameter of a small probe is much less likely.

I hope the 6-inch NM probe (LG15) will stand out, as does the elliptical 9.5″x5″ (SP24) used in my Simplex+.

It’s obvious that electronics and water are a poor combination. So, if you’re taking your expensive metal detector anywhere near water, especially salt water, it needs to be waterproof to survive accidental submersion. The Legend is fully resistant up to three meters. For diving maniacs, you can buy headphones for diving on a cable. Same as Simplex+.
