I bought a Stealth Cam last year. Since then I have used about 50 rolls of film and have only got two pictures of deer. Both deer were only the back end of the deer. The pic was too late. I have tried every combo of delay and amount of pics and I get the same thing.

I mostly get pics of nothing.

Can someone give me advice on whether Stealth will adjust the sensitivity or look at it or should I just throw it in the trash?
