I climbed a tree and put a cam a good 15 feet high in a pretty remote place. Let it soak all spring through fall. What I noticed is they loose their effectiveness as the distance increases to the trigger point. I had zero night pictures and limited day, one twighlight. Needless to say after a 5 hr round trip for retrieval I was a bit disappointed at only having 25 shots. One animal and 4 groups of hunters. I did enjoy seeing all the groups of hunters heading back down about 90 minutes later. They must have been enlightened as to the ruggedness of the terrain.
