OK where to begin. I traded a 4x6 sef butterfly coil and a 4.5x7 excelerator coil for a 12x15 sef butterfly (MONSTER) coil. It is big lol I needed something for fields and the little coils didn't work at iron sites any better than the 11 pro coil. So it comes in and I decide I want to see if I can handle the weight on an already heavy machine. My shoulder ain't gettin' any younger So I go to a site I have been to about 30 times with the DFX and a bit around the cellar hole with the E Trac. Pretty much void of targets with the DFX. E Trac found some buttons but no coins. But Iwas only there once or twice with it and never ventured out much. So I get there and I start away from the hole in the nearest field. I get a button, then another, then shotgun shells and I say, well at least it hits small targets Then I get a 12-46 reading about 5. Sure enough, in my pounded virgin site, I get a copper thumbsup01 thumbsup01 thumbsup01 Maybe I just missed it before, but I doubt it. So I venture out and on the way back to the truck I hit a 12-47, 06-45, 16-46 reading at 5. I know what that means lol OX Knob rofl No, it usually means copper. But 2 coppers with a new coil in just 3 hours at a pounded site? Yep, it was a second copper. I think I like this coil Will post the cleaned up pics as soon as I finish cleaning them. This site is one where the coppers are very corroded
