I got out for a couple of hours on Sat. & Sun. morning, man was it hot even early in the morning. Saturday I'd had my battery charging all nite for the hunt but when I put it in the detector it only showed 3/4's of a charge, and only lasted for a couple of hours. So when I got home I put it back on the charger and left it all day and nite, Sunday morning it only showed 1/2 charged and only lasted an hour, I guess its toaste. Luckly I had bought a older minelab rechargable a while back, and in 4 hours of charging it showed a full charge, so the chargers is ok I'm sure. I got one silver dime, a 1957, and 6 wheaties, 107 pennies, 7 quarters, 16 dimes, and 4 nickles out of the yard I was hunting, and it was a really small yard. I tried the 2 tone, open screen, ferrous up around the house where all the roofing nails are always so thick....found several pennies I'd missed in conductive, multi tone, but nothing really out standing. Finding coins I'd missed showed it does work, but it sure takes lots of patients. It was nice to get out, but I'd rather have it be a bit cooler, I'm out there for the enjoyment, and sweat'n a bucket load of sweat isn't exactly fun. Thanks for looking, HH ken-ks
