I think trail cameras are a great tool to use when used correctly. I think a lot of hunters can't fight the urge to check their camera and fill the area full of scent they also put it over a bait site and not on trails leading to bedding areas or food. I use trail camera's not just to see what maturity of deer I have but what direction they are coming from and when they are coming. Also, I use them to see what isn't there. If I leave a camera in a spot and production is slow on the camera then I just scouted an area that I know won't produce and move on to the next ideal spot.
