My TrailTimer Photohunter takes 1 lithium 9 volt battery. I put lithium in the camera also, and this gives me 3 to 3 1/2 months before a battery change! Thats averaging about 20 photos a week. I use 24 exposure film and sometimes when I check the number of photos I could of had in a week its around 45!

TrailTimer makes two new models the EZ cam and Ez cam plus 500. They work the same as the Photohunter, but have a new batter case. The Photohunter is around $229 and The new EZ Cam only $149 in Cabels's right now!

I also own a DEER Cam non-typical DC-100 and its nowhere as easy to use as the Trailtimer series of cameras.

Good Luck!
