Happy Thanksgiving everyone. I have been hunting with the Explorer XS since it came out. It has been a great run with lots of super finds. However, it has gotten to the point where I can hardly make finds anymore. I have always used the stock coil, and am considering making a change to a different one to see if I can once again start finding more targets. I am considering the Detech 10x12 butterfly coil, the Ultimate 13" coil, and the WOT 15" coil. Will one of these coils make my old hunting areas new spots to hunt again? If so, which of these coils would you recommend? I think I would prefer depth over separation. Thanks for any input.
