Also, the thermal imaging I can understand, but I want to know how much science is in their other gadgets. Its obviously what people want to watch, but if they REALLY wanted to find out what was going on in a spot, they would have to set up a control, and be there for at least a number of days, not just a few hours one night. UGH, sorry, I don't mean to vent, but I watch these shows and dissect them every time with my wife because I don't claim to know, but I find it hard to turn away!
