I think that has to do with how fbs behaves in ground and not so much the halo but I might be wrong.. My deus air test at 12 to 14 inchs on some non ferrous coin sized targets ... if the halo theory is true why am I not digging 18 inch non ferrous coin sized targets on these ancient sites??? We have dug thousands upon thousands of non ferrous targets off these sites ... but non past air test capabilities. All I'm saying is on these old site I have never dug a target past what my detector will air test on and some of these sites date back to the early 1700s... It might happen but imo its not the norm.. BTW the deepest coin sized target ive ever dug was 13 inchs in the ground. It was a small oval colonial buckle..
I don't have an answer for you. The deepest coins I have dug in soil have been 12 inches (with the same detector). I wish I could get beach depths in the soil! Maybe my soil isn't wet enough. Maybe my ground is too mineralized. dunno!
