Starting at 2:50 or so of the video squirrel 1 says this:
"There's some out there, you know, there telling me that they can unmistakably call every d__n piece of canslaw an every d__n nickel versus a gold ring using the audio. Well, more power to them, that's all I can say boys, okay. I would like to hunt with some of them people that say that b--ls--t."
I certainly never said that and reading posts from this and other forums, I have not read any response that made that claim as far as "unmistakably call every d__n piece of canslaw"
Canslaw that is really near the surface and big enough will give an overload audio signal. That is not BS, it just is.
Some canslaw can also have a more spread out audio response both horizontal and vertical the larger it is. That is not BS, it just is.
Some canslaw can respond exactly like a gold ring which is where your HF2 gold ring target ID variation vs canslaw next to no target ID variation tip when changing frequency Max higher, is really helpful. That is not BS, it just is.
Unfortunately that doesn't work very well where I detect because of high iron mineralization and every target can have target ID variations when changing Max frequency higher using the HF2 coil.
Some gold rings with similar target IDs sound a lot like a US nickel as far as the audio characteristics which can be heard easier with a 5 or 6 target ID nickel tone bin. That's not BS, it just is.
Many undamaged oval and rectangular modern pull tabs that have target IDs that fall into that same nickel tone bin do not have exactly the same audio characteristics as a US nickel or a gold ring with similar target IDs. That's not BS, it just is.
So, I don't get what you are trying to prove. You are right and I am wrong? What I and others are doing is BS? You are the only person with the truth and we are just liars?
