For the ultimate in detection, the RMR-8RD features an external front antenna for radar and laser detection, and an external rear antenna for laser detection (both of which connect to the display box in your vehicle's interior). The device gives you 360-degree detection of all Radar bands (X, K, Ka, SuperWide, Pulse, Instant-On, Photo, and POP) and all Laser Speed Devices (Pro-Laser, LTI, Laser-Lite, and Stalker). Adaptive laser tracking (ALT) ensures better laser performance.
Radar/Laser Scrambler Included
The "S" in RMR-8RDS is for "Scrambler." Included is the RMR-RS202D for 360-degree scrambling of all Laser Speed Devices (Pro-Laser, LTI, Laser-Lyte, and Stalker) and radar.
Lidar sends out laser pulses and measures how long it takes to hit your car and come back. From the speed of light it can determine your range. It sends out several more pulses and calculates your speed from the change in distance over time. The RMR-8RDS transmits pulses electronically timed at 100 feet apart. This only allows the Lidar to see up to 100 feet so it is unable to calculate your speed.
I wish someone could test this. I bet it fails just like the radar jammer.
