More and more police departments are using radar and laser guns to hand out speeding tickets (increasing local revenues). Almost all of us, from time to time, have accidentally crept up over the speed limit. A radar and laser detector will protect you from speeding tickets by giving you plenty of advance warning to slow down.
Radar detectors are completely legal to use in California and most other states in passenger vehicles. Drive with a sense of confidence that you won't be facing expensive fines if you creep over the limit.
Windshield mounted detectors work well and have a clear view of the road ahead. They are visually less attractive than a stealth type system, and the hanging power cord bothers some customers. We can hardwire the detector to eliminate the power cord, but the detector is still visible on the windshield.
Stealth installs incorporate the ticket avoidance product into the vehicle. Front, and sometimes rear, sensors detect radar and laser targeting and communicates information to the driver using a simple display and control system. These "invisible" systems look like they came from the factory.
