I have an Explorer 800 coil that came with my Explorer. It's a Minelab factory coil. I rarely (if ever) see any reference to this coil on any of the forums. Does anyone use this coil? It seems to work with my Etrac. I'd like to hear from anyone who uses this coil. I'd also like to hear any horror stories about this coil. I can't see buying a smaller coil when i already have one. Thanks Rayski
