So I got out for just over an hour at a Long Island beach with the new Safari. Take for the day was,one each of a quarter, dime,and penny all clad. As well as a copper screw and at least part copper nail. Everything sounded good though I dont recall the actual TID#s, I looked mostly at the bar at the bottom as well as the sound. Now is it common for the alkaline batts to drain so quickly? I've used it less than 8 hrs and it's down to 1 bar already. Would I get more time from rechargeable batts or spend the cash for the ML 3100 for $139. Money doesn't grow on trees unless you're the Federal Reserve then you can just print it.
