Steve Herschbach Posted June 13, 2020 Author Share Posted June 13, 2020 So if I adjust a TDI so the ground balance is mid-range, we have a hole. But if I adjust it to either extreme, I’m just rejecting the top end or the low end. It no longer a hole, but a cut off! Semantics, my friends, semantics. I did agree in my original post that there is no hole in the intended target range of the AQ, so basically I’m being a butt head. I’m amazed you guys put up with me. I drive my wife crazy at times, now you know why! 2 4 1 Link to comment Share on other sites More sharing options...

That’s quite a soft sell of the true ground breaking feature some people are focused on. That’s one reason I’m dredging all this up. But truth be told, I’m usually one of those all metal guys myself. Well, I’ve stirred the pot hard, you all have fun while I go open this box that just arrived from Fisher! 3 1 Link to comment Share on other sites More sharing options...
vive equinox Posted June 13, 2020 Share Posted June 13, 2020 in the end what is the interest of the mute and tone modes? they seem almost anecdotal or even secondary since one might think that it is not really beginners who will use this detector.

With a TDI no matter how you adjust your ground balance you will have a hole in the conductivity scale, and therefore some gold targets will be invisible. Or you will lose 50% of sensitivity on heavy gold ring With AQ It's not the case ! 2 Link to comment Share on other sites More sharing options...

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) 1 Link to comment Share on other sites More sharing options...

I guess we obviously don’t lose them with AQ You have said in the past that the AQ does not discriminate red centimes euros, but what about when they are all corroded and swollen as it is in the sand? The IMPULSE AQ is not a coinshooter, durind this years of development I never tested in detail the coins .... If someone wants to detect coins he must detect with an equinox or ... But they will lose 60% sensitivity on 2.5grs 18k gold ring if we compare to the IMPULSE AQ on wet sand. SEE HERE : 1 Link to comment Share on other sites More sharing options...

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. Ok, I like that my 'example' would be too tight. I used it just as a quick 'analogy' because sometimes the shape of the gold (ring) will change the VDI. I hunt all metal (horseshoe off) and some of my gold targets start out in the fringe as negative until I've dug down several inches. I agree a more solid piece of gold will have different numbers as well as 18k vs 10k. We'll just wait on what Steve has to say. Link to comment Share on other sites More sharing options...
Tony Posted June 14, 2020 Share Posted June 14, 2020 Will Platinum be “captured” in any other mode except All Metal. Potentially losing “big gold” would also force me into All Metal.......and that is fine by me. I have very little iron junk on my beaches which is also a bonus. Now where is that AQ Lite version......it only needs three knobs and just the one search mode ? PS....if anyone hasn’t seen Joe’s beach test with the nickel then you really to need to check it out........ It smokes the TDIBH on that test.......the benchmark for a nickel has a new champion. I couldn’t be happier.? 1 Link to comment Share on other sites More sharing options...
