I'm not doubting his expertise, but on the other hand, how can you say "most" good targets don't even give you a VDI number. that simply isn't true. maybe if all of your targets are 8 inches or deeper, that could be true. what if all of the targets you want to dig are 3-6 inches. you will definitely get a VDI number on every one of them. the VDI feedback usually starts going away at about 8 inches. (depending on soil conditions) I just came back from the mailbox, and the book by Andy Sabisch came today. it says that a silver quarter will give you a VDI number of 91 @ 12 kHz, and a VDI number of 94 @ 18 kHz.
Hey Corps you definitely right about the depth. And it all depends on your reactivity, if the numbers will show up. I am not the know it all.
As far as Andy's book. He is a good friend of mine, and he will be the first to tell you. Take it with a grain of salt.
It has alot of good info. But dont go be numbers!!
Ive dug silver dimes at 80.
