I'm curious if anyone here uses the White's Max. 15' coil on the MXT or DFX and if so what is your review on this coil and it's performance? I'm considering getting this coil a little down the road for my MXT All Pro. I heard that this coil is pretty heavy. This coil would be used only for searching for CW Artillery Shell's, Shell Frag's, or Artillery fuse's that are deep in the ground. I have heard that this coil is a Deep Go Getter'. Any thoughts here?
