Laser Grids

Laser grids are simple tools used by some paranormal groups today. The idea behind these grids is that, thanks to the multiple laser dots, it is easier to detect movement through the area the grid is aimed at. One of the most common grids is a green colored grid of multiple, moveable, laser dots. I have used one of these grids many times and, so far, have not got any positive results in the realm of catching apparition movement. But, I've found that it is very useful for getting an idea of the amount dust or other particulates in the air. Nowadays, grids like that come in blue and red colors as well. But, I see a flaw in the red color. Red is unseeable to night vision cameras, so if you're looking to collect video data of your laser grid test, forget about it. But if you don't want the dots messing up your night vision, go for the red. Another upgrade in the area of laser grids is a newer grid, that's actually shaped like a grid. A new laser grid available at http://www.ghoststop.com/ gives out an actual grid of small squares. That way, if it does detect movement, you can use the squares to further analize the movement and even create a 3-D image of whatever it was. Laser grids are fairly cheap and can be useful on investigations for apparition detection, particulate detection, and even as a fun looking flashlight.
