Im thinking about buying this laser thermometer its only 20 bucks i want to test my setup. I am new to the forums, i have a m47 w/cheetah + escort redline i love the redline its 90% ka in my area and i always get great detection. I am from northern VA a ton of cops around here and bs laws. I had m27s on my old car and it worked great never used the cheetah i want to make sure there is not much lag. Do you guys think that will set off the jammers?
