    Mx7, which coil is best?

    If your going to get an aftermarket coil, which would it be. The 13 inch detech ultimate or 10x12 sef coil?
    Which is deeper, which is better in minerlized ground?
    Would like to hear from someone who has tried one or both and your opinions, thanks.

    I forgot to mention that i am not a coin hunter. More a cache or hoard hunter.

    I have the Ultimate. It will see deeper than the 10X12, but not by much. In fact, I doubt you could tell the difference unless you were paying really close attention. The smaller coil will do a bit better in high mineralization, but that is true of any coil. Smaller = less ground return.
    If there's anything I hate worse than diggin' pulltabs, its missin' a gold ring.
