Hey it’s our favorite paranormal tool! It proves beyond the shadow of a doubt that spirits exist....Hate to ruin your moment in the sun, but while this can be a useful tool for the paranormal it does not prove anything in the way of spirits. Before I start getting emails from people trying to prove otherwise let me explain.
KII meters or EMF detectors come in many shapes sizes and forms. They all serve the same purpose. I've heard explanations like the one with the lights is for ghost hunting while the other ones are used for measuring EMF. Well, unless you have one that dismisses the A/C portion they all do the same thing. Yes the lights make it easier to see with the lights out. There are many different types of meters, and before you buy one you need to understand something. They have different ranges. Some are more sensitive than others, some are better used stationary than others, some need to be calibrated.
The most common KII meter used is the type with the colored bulbs that increase when EMF is nearby. These are good for finding areas with high EMF fields but the drawback is that you can’t tell how high as there is no graph to show you.
Many people use these to try to communicate with spirits, and fly off the handle when it spikes. "Ghost!" maybe. Probably not. Why? Well these meters are sensitive to everything from cell phones, radios, garage door openers, Wi-Fi and a whole range of other things you'd never guess. I have demonstrated this to people before by using a cell phone nearby. If you're like me I cannot turn off my cell phone, so if you're holding a meter and you receive a text it can make your meter spike. A very common thing today is for places to have wireless internet. Well, Wi-Fi can make your meter jump as well. Always something you should ask before you investigate.
There are those meters than are more expensive. What are the differences? Ranges and the difference between Single Axis and Tri-axis meters. Tri axis will catch more than your standard meter, but do cost usually over $150. But read carefully as some of these meters need to be calibrated and they are charged for.
The best one I've seen is the Mel Meter. It has an EMF, Temp gauge, light and a whole host of other tools. It does need to be calibrated but the company does it for free. This tool can be found for a whole range of prices but I still recommend researching.
Make sure before you spend your hard earned money on equipment, make sure you do your homework and not just buy things because you've seen it on TV or your friends have it.
The moral to this short outburst is to ensure we are using the tools provided to us the right way, and know that just because it goes off doesn't mean it’s paranormal.
