Super Bright - Covers All Size Rooms, Even Vary Large Ones
 
Unlike other laser grids, this laser with a built-in battery, can be charged directly with a USB cable.   This high powered laser emits a grid of red dots useful for detecting shadows, unseen anomalies moving across an area or general visual disturbances during an investigation. Set it in front of a running camera to catch potential evidence.    This works well with full spectrum and regualr cameras.   You can film the grid and it's easy to see any potential anomalies or movement.
