Has anyone else tried the update using the 15" coil? My buddy and I both did the update and hit up an old drive-in the other day that's now just an open field. He had the stock coil on and I was using the 15". The update seemed to work great for him using the stock coil but for me right away I was noticing lots of bottlecaps, way more than before I did the update. I think I dug 27 bottle caps in a few hours. We were running the same programs and settings and trying to figure out why I was getting so many caps and he wasn't. We put a few different styles on the ground and his was hitting them at VDI 21-22 and had a distinctive BONK on the end of it and not real solid. The 15" was reading them VDI 24-25 and no BONK, just a crisp high repeatable tone on every one. I know the aluminum caps are not so avoidable but this was every type of cap. I tried park 1, park 2, iron bias all the way up, recovery speed up, recovery speed down, all metal mode. Anyone else experience this with the 15" after update? The 15" probably isn't ideal for high trash sites but it's my fav. coil for the Nox so I guess I will roll back the update for now. Ended up with 2 silver and 27 bottlecaps. Buddy got 4 silver and 3 bottlecaps...
