The 10 x14, I feel, is the best "large" coil there is for the Explorer series. I literally hunt with it in dense trash after smaller coils and still dig coins I missed. I have not been able to do that with any other coil larger than the PRO11 ML. As for the 14 and 16, they kind of get overtaken by the soil and get less depth for me, not more, I have not found a use for them and I hunt plowed fields, so that's pretty sad. In fact because the ML Pro 11 is so stable, I can run manual sensitivity maxed and get better depth with it than any coil larger than it, including my 2 WOT 15's, SR 12, Excellerator 14 and 16, and the SEF10x12, and SEF15x12. All this is on my SE's. The 10 x 14 is the only coil I have had that competes with the new Pro11, both for depth and separation, it is truly an awesome coil. You'll end up with Popeye arms though.
