Laser Grid Pens

Green laser pen pointers that fill the room with small green laser dots have fast become the next must have accessory on the ghost hunting scene after they were used on the US television show Ghost Hunters a few years ago. Various ghost hunting equipment sites stock them and say:

“This high-powered laser emits a grid of green dots useful for detecting shadows or general visual disturbances during an investigation. Set it in front of a running camera to catch potential evidence. 6x STRONGER than the imitators. You can adjust the size and shape of the stars by turning the adjustable lens. Detach the lens and it will function as a high-powered laser pointer viewable for 8 miles!”


So the reported benefits of this green laser grid pointer are:

– Good for detecting shadows
– Good for seeing general visual disturbances
– Good for catching potential evidence when in front of a camera

It’s very difficult to see why this device has any place on a paranormal investigation as there are some major flaws with it and the theory behind it.

1 – If anything, this laser device would make observing your surroundings harder.
2 – Shining a laser around in front of a camera lens is likely to cause light flares and illusions on the camera lens.
3 – Investigators would be more likely to observe illusions because of this device because not only are they standing in the dark, they’ll have laser lights all over the room messing with their eyes.
4 – It has only become popular due to being used on a paranormal television show. Ghost Hunters is a show that claims to be scientific in its approach when we know they are not, and have a very mixed up view of what science it.
5 – It would be easier to view shadows and “general visual disturbances” by turning on the lights.

 If you want to see shadows or any possible “general visual disturbances” little green dots are not going to help you.
