Man that sure sounds like some brutal testing Monte. Especially listening to that thing for 27 hrs at a time. So you really think running headphones will give the RNB battery an extra 3 hrs like the manufacturer says??
Though of a great idea. Put out some coins, tokens rusty nails whatever. Strap the detector to one of those oscillation fans so the detector can constantly swing over the targets back and forth ha ha ha ha. Now that be funny. True test though. IF ya do post some pics lol.
