Would like some feedback on the power of the detector at say, half charge. I was going over an 1870 house that i cleaned up on 20 years ago with my old analoge. Was just not getting deep hits on anything. Was incredulous that there wasn`t at least a wheatie i had missed. Of course i did work it hard with a heavy 11 inch coil then, but I still suspect the lower battery was makin the SE less hot. What do you guys think? HH
