This past week I had my first chance to use a new bit of ghost hunting technology, the laser grid. A laser grid is basically a laser pointer that has thousands of small points that are cast on a wall or surface. Most of them are sold with clamps that allow the beams to stay lit. This allows you to leave a grid in a room with just a camera to monitor it. The idea behind using the laser grid is that it is supposed to help visually catch the movement of shadows in a space. People often claim to see strange shadows in haunted locations and this is a device that is designed to make those shadows easier to document. Unfortunately we weren’t able to capture any activity with it.
We actually had several problems with the model we were using, The Green 30mw Laser Pointer Pen Style Star Holographic Projector and Laser Point (yes that’s its real name.) The main problem was that after turning the laser on, the beams would dim after several minutes and become almost invisible. We had to constantly restart the grid throughout the night. I looked at reviews on Amazon prior to writing this and many other people have complained about this problem as well. Also, the lights were invisible on our IR camera so even if we saw something with our eyes, we would have no way of documenting it on film.
Ultimately, while I think the idea of the laser grid is a good one, this is an object I would not recommend purchasing, unless you just plan on using it for a fun light show. I might have a better opinion of a stronger version of the laser grid. I give The Green 30mw Laser Pointer Pen Style Star Holographic Projector and Laser Point 2 out of 5 ghosts.
