The police use Pro Laser III, Stalker LZ-1, LTI Ultralyte (with optional Distance Between Cars mode), Laser Atlanta SpeedLaser (with optional stealth mode), Kustom Signals ProLite+, and LTI TruSpeed laser guns. Each police agency uses different types of speed laser guns which depends on the agency's procurement. A driver could encounter any one of the speed laser guns listed above. Since different police agencies over lap most areas, the local, county, and state police agencies could be using different speed laser guns in the area. Blinder laser jammers detect and jam all the speed laser guns police use to issue speeding tickets. Drivers without Blinder laser jammers fall prey to these speed police laser guns every day. Drivers with Blinder M27 and Blinder M47 laser jammers are 100% protected from all speed laser guns.
