For nature lovers that like to see the wildlife around them, can use a game camera.
For bird lovers you can put a trail camera near a bird feeder and see the birds coming to the feeder and also see what you don’t want at your feeder such as squirrels, cats, bears.
I was talking to service tech. that came to the school were I work to do some service and I asked him if he hunted for deer and he stated that he just bought a game camera not for deer hunting but for surveilance for a home he is building he had some vandalisim.
For the avid hunter that wants to see the deer, bear, or see who is messing around in your hunting spot it will record the time, date, moon phase ect. Also do daytime and night time picture with infrared flash and do color picture in day time.
