no argument from me faiz23, as our young officers test this crap all the time, we just then train to use our tools differently...think of it this way, if we are just in an area to get people to slow down, then our units are left on, and we take what we get, we know people are out there detecting us, and they are slowing down, mission accomplished, but if we are in the hunting mode for real speeders, the units are left off until we see our target...thumb, faster than foot....gotcha ya...while we are getting you, all those with detectors are slowing down...as for jammers, you have to be right on top of us, and they don't work for moving or stationary at a distance...we have young guns improving our equipment too...techs are making money on both sides of the coin...but I have done this for 30 yrs, from old to new, and my favorite was VASCAR...no signal at all...a timing device...nothing you can jam, nothing you can detect...
