Has anyone else tried this for finding gold? thru the high tone falsing low tones stick out like sore thumbs was a bit curious if anyone found gold that registered in a higher tone on air tests you can hear a nickel very audibly from 10 inches, tried it on a beach i wasnt getting any signals on running 25 man sens which was stable all around but wasnt getting any signals switched to 32 man and hit a low mustve been atleast 10 -12 inches with the sand shifting when i switched to AUTO id lose the signal but in MAN i had it still you could hear the low thru the falsing and it was an old style pull tab so a normal sized target. Has anyone else tried this with success? it just seems low conductivity targets respond alot better with the sensitivity maxed i also used next to no iron mask only 2 notches above from a clean screen.
