The SpyFinder Pro is a lightweight battery powered device that allows you to quickly identify and locate a camera by using an array of ultra-bright LED's. When the camera is found it is highlighted to the user, where it appears as a flickering bright spot of light. The SpyFinder will find any hidden camera transmitting or not. It’s so small you can carry it in your purse, suitcase or briefcase to have it with you at all time.
