Testing The Depth On The Nokta Impact! (Photos, Results+)

Hello friends, fellow detectorists and fans of our hobby!
I recently went into the woods to test a new detector – the metal detector Nokta Impact from the Turkish company Nokta Detectors. For depth tests, I’m generally very cautious, because so many people try to wind up the result in one way or another, to sell more detectors.

I stand a little away from this, I’m more interested in the real and practical result, and therefore I do the tests according to my scheme: I do the test in places where I dig (the ground is quite ordinary). I do the test on the settings on which I am digging, and I’m digging on a universal scheme, and not using special settings for certain tasks (beach detecting, etc.). The settings are for SEARCHING and LOCALIZATION of the main place and site, which must be set to zero, because of the large concentration of useful finds. And what is it for? It’s very simple, I’ll explain it in a simple way: Any detector can be wound to the maximum depth, but with such settings you will dig faulty (too many false signals, strong sounds from the ground). Let’s call it “unrealistic settings”. Yes, the detector will maybe look deeper, but this is not enough from a practical point of view.

So, all these waving with a coil over the targets with nails and coins – is a circus, in some way. The settings should be updated with your everyday detecting and then to test it.

But enough of that, here’s what I did to perform the test: I Put the Nokta Impact on the usual settings for everyday detecting – the modes “DI2” and “Deep”, and the sensitivity was in the range of 81-85 (you can put more, but I did not because of false signals), and of course the ground balance per the ground – in my case, the value was always the same – 73.

But why test with such a small coin? Well, because it is one of the smallest coins that can be found in our region. A small silver target will perfectly show the possibilities of the detector in an ordinary day of detecting.

The result was 15 cm in the “two tone” mode – DI2, this is a good result. Let me remind you that for many detectors, this “flake” of a coin becomes invisible in the range of 2-7 cm. For metal detectors, the result of 15 cm is already mandatory, in my experience and observation. So, the standard for my test is 15 cm! However, it became interesting to me to check the capabilities of the detector (practical) even more seriously and I checked the detector in the DI2 and Deep (deep) mode. In the metal detector Nokta Impact, there are several depth modes, they differ in the principles of operation and factory settings, but for most tasks the Deep mode will work.

The result

And here is the result: In DI2 mode (two tones): At 15 cm, the detector saw the coin at all frequencies. At 18 cm, the detector saw the flake stable only at a frequency of 5 kHz, the remaining frequencies gave the object a sound signal, but without the numerical index VDI. In Deep mode: At a depth of 25 cm, the metal detector saw the coin at all the frequencies! Now this result really impressed me! What do you think about this?
