I'm looking seriously at one of these "10 x 14" EXcelerator II EQ2 Pro Search Coil" for my Ace 250. This one, along with my standard coil and my "Sniper", I think, will cover any detecting situation I may come up against. It's on sale at Kellyco for $99.95 and the "9x12 PRO formance Elliptical" coil is going for $99.95 at Garrett. Same price...is one better than the other? Have any of you guys tried out one, the other, or both? Opinions/reviews will be much appreciated.
