The
Rocky Mountain RMR-C450 Laser/Radar Detector is the best
Voice Alert and
Laser Detector Scrambler on the market with a 2.5 - 3.5 mile range. It will visually and audibly notify you of police radar and laser guns attempting to read your vehicles speed. The
Rocky Mountain RMR-C450 will also momentarily scramble all radar and laser signals from a police radar or laser gun returning a blocked signal, making it virtually impossible for police to read your vehicles speed just long enough for you to hit the brakes.
Rocky Mountain RMR-C450 Laser/Radar Detector's state-of-the-art
Radar and Laser Detector will cover your vehicle a full 360° while the radar and laser scrambling portion will cover the front of your vehicle 180° for unbeatable protection. This
Rocky Mountain RMR-C450 is a passive device and completely legal in all states except California, Virginia, Washington D.C and possibly some other states – check with your local authorities if you are unsure.
The
Rocky Mountain RMR-C450 Laser/Radar Detector detects X, K, Ka radar frequencies and works instantly on radar/laser guns and has the ability to scramble any signal it receives. The
Rocky Mountain RMR-C450 do not transmit radio frequencies. The radar portion is a receiver not a transmitter. This is why these
Scramblers are legal.
They have an
FM chirp, a mixer, and a waveguide antenna for all radar bands the FCC allows the Police to use (7GHz - 38GHz). The lidar ( laser ) portion transmits a specially modulated field of light from the vehicle with infrared diodes that cover all three laser guns in use today. The radar and lidar portions of our
Scramblers confuse the radar and laser guns which prevents a hard reading of your speed immediately. This makes your vehicle temporarily electronically invisible to police radar and laser guns.
The radar scrambling circuit mixes a doppler
FM chirp with the incoming police radar signal and reflects it back to the radar gun. The computer in the radar gun must receive eight identical, consecutive readings before it will display your speed. All the different speeds contained in the
FM chirp confuses the computer in the radar gun so it does not display any speed immediately. This effect duplicates the normal operation that the patrolman usually sees. As it is normal for this to occur periodically, the officer can not tell whether you have a
Scrambler or not.
