DFX w/ 12x15 sef coil, sunray pinpointer
Hi, have a question about the 12x15 sef excellerator coil. I have been using it for a few weeks now and it is a good coil and I think it does go deeper than the stock 950 coil on the dfx, but it seems like the vdi numbers jump all over the place with deeper targets ( 6 to 9 inches). Also seems like when i'm pinpointing it is centering the target from the front of the coil to about three quarters of the way down the center of the coil. With the stock coil it was very accurate with the target in the middle of the hole in the coil but this new coil seems to have a wider area and not really a sweet spot. Has anyone else had an issue with this?
