RE: Would you put a trail camera with flash under your stand?
We NEVER put a camera in an area we anticipate hunting. We only put them on easy to access field edges, over mineral licks, or water sources.
Consider everytime you check your camera, you leave human scent to and from the area. You go into an area that you are hunting before and during the season for any other reason than to hunt and you are just waving a big white flag saying "hey - this is where I'll be". The only thing a hunter can have is the element of surprise. Don't ruin that!
