Nokta Amfibio field test

Some time ago, we received a pre-production piece of the new detector from the factory to test. Although we have been with the detector a few times, I decided to give it a try and try different settings in the field.

Mechanical design

Although it doesn't seem like it at first glance, there are quite a few significant changes in the design and elsewhere. The first is probably the use of a telescopic design, which is the first time I've seen that with this manufacturer, otherwise the whole design is based on the Impact design. Triangular profile bars are used, which prevents the bars from rotating on axis, and the quick locks make the structure fold and unfold literally in a flash.

The armrest and its locking mechanism are also quite interesting, again allowing the position to be changed in a matter of seconds. Also worth mentioning is the interestingly designed space for the power bank under the armrest. Instead of a lever under the unit, for waterproofing reasons, you will find a ground tuning and pinpoint on the main keyboard. The entire detector has two waterproof connectors, where one logically serves to connect the probe and the other will serve as both a charging and as a connector for waterproof headphones. The detector in all versions will include wireless headphones, so the detector does not have a classic headphone jack. For one thing, this loses its meaning when wireless headphones are included in the kit and using this connector would be highly problematic due to the waterproofness.

Behaviour and settings of the detector

Here it is nice to see how each company tries to maintain its typical signature. I probably found the controls and behaviour of the detector most similar to the Impacta, as I have walked the Impacta before and had no problems. I could basically pick up the detector without opening the manual :D. There are a total of 9 working modes. If I start with the basic ones, 2-5 TONE, it's basically an alernative of DI2,3 etc that you know from Impacta, Relica, Core etc.

Although it might seem that these programs differ only in tonal equipment, the opposite is true. As users of previous models will probably give me credit, the DI3 program, for example, was quieter than DI2, while DI2 was a bit sharper and went more in depth.

It's the same here. DI2 and DI5 seemed to me to be the most profoundly powerful programs. If for some reason the 5-tone mode doesn't suit you, there is a fairly easy way to set up the detector tonally in that mode, such as 3-tone, so that the other features of the program remain. In the settings under TONE there is an option to set individual ID sections to the same audio frequency, thus sort of merging two or more tone sections. Under TONE BREAK you can then stretch the ID sections as desired. Furthermore, you will also find specials such as the DEEP-depth program, which prefers a slower movement, in the program menu. This mode operates in two-tone mode, quite similar to the 2TONE program, and is well suited to clear woods with well-penetrated terrain.

CACHE-an in-depth program specifically designed for large targets that operates in single-tone mode with discrimination. Again, it prefers slower movement, which results in a significant increase in depth.

General - Allmetal mode without discrimination more suited for surveillance.

Beach- mode for salty sea beaches. Unfortunately this summer is gone and I have no way to test at the seaside :D
Quite interestingly there are two ways to discriminate here, either classically via Disc or NOTCH. With the addition of discrimination, the detector calms down a bit, but the discrimination takes away a bit from the range. As a second way, one can select one of the tone modes and set the tone breaking to the desired value via the TONE BREAK item and then mute this tone to 0 via the TONE V (tone volume) item. This setting can be used to control the volume of any tone. Discrimination done in this way does not detract from the range, but it is not as precise as the previous case.

Conclusion

I tested the detector on quite heavily mineralized soil, yet I would say that it showed quite decent results, which I attribute a lot to the new type and especially the shape of the probe.

In about a couple of hours I pulled up quite a large number of coins often from respectable depths. Unfortunately only one silverfish fell on the number of coins, but I will definitely be back :D.
