Bests & Worsts Reviews from Amazon

First off to all the "Ghost Hobby Hunters" let me state my qualification for this review. I run a business which custom develops and manufactures various electronics for federal agencies that require tolerances so precise most large companies don't want to deal with it. I have a family member who has also been swept up in the whole ghost hunting thing and purchased this meter. After showing me a few videos of "possible" activity based on strange readings from this meter I asked to borrow it for a few days. At first it seemed decent (for the price) as far as accuracy. When swapped out the battery for one aprox. 15% drained (which is about what you would have with a few hours of use) the accuracy range dropped to 8%-30%. WOW! I also found several spots on the board where the voltages became erratic with used batteries. At this point I decided to put it up against a few AlphaLab Gauss Meters (ranging in price from $400-over $1500) and in my opinion this meter only gets aprox. 40% to 70% accuracy. Now before the fanatics start getting mad let me make a point. I don't consider myself a "Paranormal" type but it has caught my attention especially after my father died from ALS. I have been asked by a friend of mine to join their group on a few cases in which I was shocked to find some of the other members included a retired Bechtel physicist, DSS agent, and a few other scholars. For me it seems intriguing to think about and it does need more research from the scientific community. Having said that it also seems obvious you would want any evidence acquired accurate and UNDENIABLE. This meter in my opinion this meter is far from accurate and should not be used for scientific proof. If this is just a hobby kind of thing and you are into paranormal stuff for excitement than it is probably good. If you are taking this kind of research seriously than you should consider a Gauss Meter similar to the one below. Digital Electric Field Meter
