It's true, but in some very polluted areas it makes it easier to sort and detect gold under the iron. I did an experiment several years ago in TONE mode in an extremely polluted place on 600 holes I detected 30% of non-ferrous target below ferrous target. Impossible to make that in ALL METAL mode I confirm that MUTE mode is less interesting for the expert. (Only if you want to cut a light magnetic ground without using the VOLCANIC SAND MODE)

The range of VDI with your 800 is not the same moreover it is too tight to be valid. If you take an ingot of one kilo it will be in the upper part so it will be rejected in MUTE, detected in TONE MODE with a low tone. These detection modes are really made for beginners, because the expert detects in ALL METAL mode and 99% of ferrous metals are easily identified with a double beep.

Yes that's what Carl explained ! 😉 And since all gold jewelry is not located in the upper part, there is no hole in the conductivity of gold jewelry. If you take an ingot of one kilo it will be in the upper part so it will be rejected in MUTE, detected in TONE MODE with a low tone. These detection modes are really made for beginners, because the expert detects in ALL METAL mode and 99% of ferrous metals are easily identified with a double beep.

I repeat : Let us take an example, on the conductivity scale of a White's Spectrum XLT, the non-ferrous going from 0 to +94 and the ferrous 0 to -95. The IMPULSE AQ detects all targets with a VDI ranging from 0 to 58 as being valid targets. And the IMPULSE AQ will minimize the loss of depth on the highest VDIs. (almost 55) It will therefore detect between 59 and 94 the targets as invalid If your coin is at 75 it will not detect it. An 18K gold signet ring of 20grs is only 45 therefore detected ! Can be that a signet ring of 45 grs 18k will have a VDI of 70 (I don't know I have never seen one) then it will not be detected in MUTE mode and it will make a low tone in TONE mode. (But there will not be the double beep which shows more than 95% the presence of a ferrous)

Hello, Regarding a metal detector model for finding gold nuggets, I would not comment today. Regarding the IMPULSE AQ, there is no problem in the conductivity scale of the low conductors. Let us take an example, on the conductivity scale of a White XLT Spectrum, the non-ferrous going from 0 to +94 and the ferrous 0 to -95. The AQ pulse detects all targets with a VDI ranging from 0 to 58 as being valid targets. And the IMPULSE AQ will minimize the loss of depth on the highest VDIs. (almost 55) VIDEO HERE (Sorry for the rude English)

Yes that's correct, I have several production models and I allow certain Youtubers to meet us and make videos ... I don't have much time but I try to do it more and more. It makes me happy to chat with prospectors. I gain knowledge about what they like and how they see their material and the passion in general. -

I think the next videos are coming next week on several Youtube channel -
It's very interesting, I didn't know at all. They keep repeating that for the USA and Africa, we have to find more small, 1 grain, 1/2 grain and 1/4 grain if possible. While in the field I have a lot of prospecting friends who tell me the opposite, they want to look for big nuggets larger than 2 grs.

This is an interesting subject that few people know how to deal with even at the metal detector companies. Impulse AQ must pass over all types of magnetic soil, fe2o3 and fe3o4. On the other hand it will not take small gold nuggets, it is not planned for that. The impulse gold model will be provided for this research ... Impulse AQ does not detect below 0.1 gr / 0.2 gr, however it cuts very very hard this type of ground. Especially in volcanic mode. http://www.zhinstruments.com/sm_30.htm I have enough stones from all over the world to open a stone quarry. I was able to volcanic sand 10 times more intense than the most difficult of my volcanic stones. HERE 325 x 10^-3 SI No problem with AQ :
