We’ve had a discussion about the legality of laser countermeasures. There are no federal laws against the use of laser countermeasures, but many states have passed bans on laser countermeasures (laser jammers). We don’t test products violating federal laws meaning radar jammers. Before you buy, check local or state laws regarding this product. If you are stopped by law enforcement and they know you have a laser countermeasure, expect a ticket instead of a warning. Some laser guns, i.e., Stalker and LTI laser guns tell the operator they are being jammed. The two leading laser guns in the law enforcement market come from Laser Technologies Inc. and Kustom Signals Inc.

Test vehicles equipped with laser countermeasures weretold to count down, “3, 2, 1” as they approached both the 1,000 foot and 500 foot cones. They were instructed to travel at 30 mph. Certified police officers and/or factory laser gun representatives operated the laser guns.  They were told not to pan or follow the target vehicle, but to target the vehicle at the different locations. Aiming point was the front license plate. J means the device jammed the laser, NJ means the device did not jam the laser, A means the device alerted to laser’s use. NA means the detector did not alert to laser. Passport/Escort/Beltronics call their countermeasure laser shifters. Each device was given two runs at each laser gun.

The results show that laser guns are increasing difficult to jam as laser gun technology moves forward.  Honestly, if officers don’t get a speed reading while using a laser gun they simply move to the next target. There are plenty of targets! We can’t report the results of LTI Model “S” as it does not appear on the 18 July 2011 listing, Conforming Product List, of the International Association of Chiefs of Police. The LTI TruCam and Laser Alley presented major problems as laser jammers had difficulty in jamming their guns. The Blinder M27 had the most success in jamming laser guns.  Computer programs are available from the laser jammer makers to upgrade individual devices as new laser guns enter the market. As we have said before, the major announcements in the law enforcement market come from laser gun manufacturers. Expect to see more laser gun use in the future. Honolulu does not own a radar gun, only laser.
