Fresh water beach depth ?

[jerry123]

Took my cz 21 and fors core to a Lake erie beach yesterday. I buried a nickel at 9" measured in dry sand and checked to make sure it was metal free. Ground balanced Fisher cz21 and got repeatable signals with iron eliminated. Ground balanced the fors core in D12 sens at 95 no signal did the same in D13 and cog with same results. In General mode I was able to get repeatable signal. Do you think the machine should have got a signal in one of the other 3 modes ?
Any tips would be appreciated.

The Fors Core achieves good depth in COG mode but only with a setting of 98 and higher when approaching ground balance numbers of 0.0. Try 98-99 sens and ground balance the machine, set your ID mask at 20. In the super salty wet sand beaches of South FL 10" are easily attainable on nickel size objects.

Thanks Digger, Did you mean to turn the ground balance down to 00 manually?

No simply ground balanceto your soil conditions and keep sens at a minimum of 98 and the core will go fairly deep on the beach salt or fresh.
