I got the pin pointer a couple of years ago from a dealer friend who was going out of business and he gave me such a good deal I could"nt turn it down even though I have no use for one as I never cut a plug or dig a hole. The only time I used it was with the Ace 250 looking for roofing nails in the yard a year or so a go.. I never did any detecting last year as on my next birthday I will be 85 and am wearing out. So the Carrot was not used till I checked it the other day and the battery was dead. Made the mistake not taking the battery out when I put it away.There was no sign of leaking and when I put another battery in it worked great. The next day no go, put in a brand new battery 9.4 volts and it worked great,24 hrs later tried it and no go, checked battery and reading was 4.4 volts dropped 5 volts in 24 hrs with carrot turned off. Any body ever hear of this happening? What is my next move? Garbage can as I never need one. KRT
