Like what?......Honestly, not bein a turd.I would not do that. Found some great stuff reading at about a 7-9.
To not listen to thousands of trash signals I would guess.
I usually notch out up to 10 , then after a few more hours of hell, I tend to notch out everything up to about 18 or 19.
I know I notch out some good stuff, but I dont hunt places that would have much chance of gold, and I dont really care to dig a thousand pulltabs for a nickel.
Some good small stuff gets down averaged into that region (even negative in some cases) but if you are just silver/clad coin shooting (and not looking for small nickels, older small coppers, 2 cent pieces, or trimes), jewelry, or relics (which can show up as any positive number), by all meams notching to just above zincs makes sense. I just can't limit myself to those targets, personally. So I focus on the audio in addition to target ID and mostly hunt with no discrimination.
