or maybe even a zero level class - I know nothing about trail cams but would really like to set one out on an elk water hole and see what happens. What I would like to find out (without buying several first) is what to look for in a camera. What brands/models seem to work best. And what do you get at different price points? A few things I would like to have in a camera are small and light size. These will be used in the mountains and getting set up is a big effort. AA batteries would be a plus - all of my flashlights, gps etc are AA and it would be nice to not have to carry an additional battery size. SD card - so I can use my camera for a viewer. Any advise appreciated.
