Today while i was hunting the battery in my pro pointer went dead. I went to the truck and got a 9 volt battery i had in there. After i put it in i pinpointed a couple times without a problem. Then all of a sudden the pro pointer went nuts and was just blasting out a repeating dual tone. The battery i put in was a heavy duty Rayovac. After removing it and putting a different brand in the pro worked fine again. thinkingabout:? maybe the heavy duty one had too much power, i don't know! Anyhow just an FYI.
