Just some info on the GM at the beach
I thought most of you gold hounds would see my post here
Tried the machine out at a salt water beach, for testing, with stock larger coil.
Well here goes
Dry sand works great no problems will find coins in the 9 in range 90% power
Damp sand all metal mid / low setting some falsing ( in all metal the meter works )
Wet sand, all metal some falsing , run in all metal with auto ground + surprise it ran pretty quiet.
A brisk coil sweep, the iron meter is very accurate, the GM is a quick response target machine ( mxt ect. )
Not too much contemplating to dig or not, meter + dig meter - no dig (da)
For you beep and dig folks that are used to the Tessoro's sound the GM sound reacts similarly to small foil, scratchy
Uneven , not smooth. Small gold chain is a solid coin like sound ( that's good )
I was primarily testing for chains ( gold 14k small link 5in/silver 925 small link ) that most machines can't find ( even in an air test ), or sound like trash.
Small balled up foil sound solid, but can easily be kicked aside.
Just had my test chains burried 4-6 inches no problem detecting them wet / dry
One of the few machines that can find small gold chains at the beach is the whites GMZ, or the GMT both of which have a
Setting for salt/iron that does raise the gb enough to quiet down the falsing somewhat but lowers the detectability.
If specific looking for gold or silver chains at the beach the GM excells quiet well for a single frequency VLF.
