I've been out w/ the AT Pro twice now and have noticed a few things while digging in playground/beach sand:
I've hit/found several pennies - always clearly reading low 80's up to 8-9" - no problem.
Every once in a while, the Pro will give me several readings ranging from 5 up to low 70's - when I dig it, there have been a couple occaissions where i find nothing.
My concern is that I might be having these "false readings" i'm reading so much about. My challenge is that I'm brand new to this and the machine does seem reliable most of the time.
If I am experiencing the falsies, wouldn't I be experiencing them all the time instead of once in a while.
It might very well be that I'm in highly mineralized sand. I have been regrounding regularly with a grounding of up near 90 - which i gather is on the high side.
Any advice sure would be welcomed.
Thanks!
