The Laser Grid
This is a fun gadget that has proved itself a valuable tool. The unit projects a very large adjustable grid of laser spots onto any surface in its path. By training a NightShot video or DVR camera on the grid. you can watch for spatial distortion in the beams when something passes through them. If you are lucky enough to have a mist or ectoplasmic entity, it will light up like a Pink Floyd concert! It is actually a moving kaleidoscope, but can be stopped in a stationary pattern of your choosing. Plus, when the investigation is over, you can have a disco party! A quick tip, check the party lighting section at you local mall in Spencers gifts for examples of these fun tools! Lots of fun lights to experiment with in there, strobes, blacklights etc.
