I like to know when bears are in the area. The alarm i seen a few months back is a little easier than the one above. IT used a personal alarm, laser, and night-light with the photo sensor. ( all can be found at my local dollar store )... THE problem with this is, its plug into the wall for a power supply. I need it portable. someone with a little electronc experance could figure out to step down the power for the night light it should work ... any ideal emailmail me thanks alexjr8888@hotmail.com hey i guys was looking for this laser alarm to set up when i go camping .
