Hi all, Today I did some testing in TTF with the 8x6 coil and I was surprised at the results I got. This is definitely not a scientific test by no means and I know in the ground everything is different especially when the targets are at different depth to each other. I took some silver dimes and a buff. nickle and laid them in a clean section of my yard with some nails next to them and put the machine in TTF and did a ground balance Then I ran the 11inch coil over them and I picked up the high tone of the coin good enough to work the target and zero in on the coin and get some good numbers on the screen. I then switched to the 8x6 coil and re-ground balanced and ran the coil over the coins and could not pick up the coin at all. I repeated this several times. I got one little slight bleep one time which did not give even a hint of good numbers on the screen. Has anybody else ever tested TTF with the smaller 8x6 coil? I thought the smaller coil and TTF would be a killer combo but now I'm wondering? Thanks all and HH.
