question for sandshark users

[jimmy clark]

I just bought a used sandshark didnt have a users manural.so question is what is the F setting an how does it work? an does anyone know what kind find of depth does it get in fresh water? i also use a tigershark but thought i would try a pi.

the F setting is to set the frequency of the threshold and target if your not using the VCO option.you can download manual from Tesoro web site .

I'd expect an inch or maybe two deeper than the Tiger Shark on sizable targets. Not as sensitive to very very small targets as the Tiger is.

If you like to find bobby pins, it will find them deeper than you really want to dig. You can learn to mostly tell if you are sweeping over a bobby pin. Sweep in different directions. A double blip along one direction and a single blip from 90 degrees to the double blip is a pretty good indicator ... but then again, a couple years back, I did dig up a thin ring that sounded like a bobby pin. I figured the ring must have been on edge in the sand.
