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.
