Just got one to try out. Opinions? How does it compare to the 10" D2? Ground is really dry here now, and the 8x14 only gives a iron grunt on my 10" deep .69 cal bullet, where the 10" D2 gives a high tone 2 ways. I got the 8x14 because I had a 10x12 SEF, but I think the D2 is a better coil than the SEF. I want to believe that the Whites coils work better on the MXT because that is what they are designed for. Oh, I had a Super 12 and was not impressed with it because our ground around here is a little hot and the concentric coils do not get the depth that the DD coils do.......MO
