I have 2 Camtrakkers and 2 Stealth Cams. All work great.The Camtrakker are much nicer but cost more. I have had a few problems with the Stealth Cam not catching the whole Deer ,but they are good for the most part. 4 C cell batteries will run the camtrakker for 3 months. 8 AA in the stealths last 2 weaks. Camtrakkers have better camo and lock to the tree. I know if they want it the can get it ,but at least they cant just walk away with it. My tips for both cameras are not to waste your film over a bait pile but rather a trail leading up to it . This will keep you from burning a whole roll on 1 or 2 animals. Since you can not lock the stealth cam as well I would try and hide them by using a hot glue gun and some fake leafs.You can get the fake leafs,ferns,ets. at wal mart. Glue they to the camera leaving the lens and so forth exposed. If you leave your batteries in the stealth cam past 3 weak you will not be able to rewind your film, so take fresh ones with you.
