Nokta Impact – video depth test (25 cm scale? Easy!)

Hello friends! Comrades, comrades and lovers of our hobby — instrument search with a metal detector!

I recently went to the forest, testing the depth of a brand new device — metal detector Nokta Impact from the Turkish company Nokta Detectors. I generally treat depth tests very carefully, because a lot of people in one way or another try to inflate the result in order to either sell more devices (sellers) or somehow praise the device (various device owners). I stand a little aloof from this, I’m more interested in the real and practical result, because to avoid accusations (and there will probably be a lot of different carrots in the world) I do tests according to my scheme:

1. I do the test in the places where I dig (the soil is completely ordinary).
2. I do the test on the settings on which I am digging. Moreover, I dig according to a universal scheme, and not using special settings for certain tasks (digging on the beach, in a trash can, etc.). Settings specifically for SEARCHING and LOCALIZING the main place and area that needs to be knocked out to zero, due to the high concentration of useful finds. Those. intelligence settings, figuratively.

What is this for? It’s very simple, I’ll explain it popularly:

• Any device can be set to maximum depth, but with such settings you definitely won’t be able to dig (too many phantoms, strong sound from the ground). Let’s call this «unreal settings». Yes, the device will look so deeply, but this is of little practical use.
• Anyone can be made to work as quickly as possible (debatably, it depends on the model, but for all non-budget employees this is relevant). Which means all this waving the reel over targets with nails and coins — the essence of the circus, in some ways. The settings should be set to be relevant for your everyday cop and then look.

Video depth test of Nokta Impact

What I did:

Put Nokta Impact in normal settings for cop — these are the DI2 and Deep modes, the sensitivity was in the range of 81-85 (you can set it more, but I don’t set it, phantoms), the ground balance is in accordance with the ground — in my case the value was always the same — 73. Checked all frequencies — 5 kHz, 14 kHz and 20 kHz.

Why scales?

Yes, because this is one of the smallest coins that can be found in our region. A small silver target will perfectly demonstrate the capabilities of the device in an ordinary cop. The result is 15 cm in «two tones» mode. — DI2, this is a good result. Let me remind you that for many devices the scale becomes invisible in the range of 2-7 cm. For more serious metal detectors, a result of 15 cm is already mandatory, in my experience and observation. So the standard reference for my tests is — scales and depth of 15 cm!

However, I became interested in testing the device’s (practical) capabilities even more seriously and I tested the device in DI2 and Deep modes. The Nokta Impact metal detector has several deep modes; they differ in operating principles and factory settings, but for most tasks of selecting targets, the Deep mode will be enough for the ears.

Test result

For those who are too lazy to watch the video or don’t have time, here is the result:

In DI2 mode (two tones):

At 15 cm the device saw flakes at all frequencies.

At 18 cm, the device saw the scale more or less stably only at a frequency of 5 kHz, other frequencies gave an audio signal of the object, but without a VDI numerical indicator.

In Deep mode:

At a depth of 25 cm, the metal detector saw the scale at all frequencies.

And the main result will be further — in the next video. To be continued!

Nokta Impact is a new metal detector released in 2017. Everything about Nokta Impact is collected here. We will add more depth tests soon, wait for the results. 🙂
