These are supposed to be more stable for the big coils. Had to notch another end cap--terrifying. Sharp little coil for sure probably a lot better in the black sand than the 10". Was doing some testing with a "puck" of Cally black sand and even with this coil the second you move it in closer to your test target the responses become way more clipped--a real lesson in how BBS machines perform. Makes a strong case for slowing down, turning it down and alternating between disc and "reverse" hunting.
