Today, Rocky Mountain Radar offers drivers a perfect solution to speed trapsóthe Phazer. It uses a passive radar scrambler to make your automobile electronically ģinvisibleī to police speed-detecting equipment. The radar component works by mixing an X, K or Ka radar signal with an FM ģchirpī and bouncing it back at the squad car by way of a waveguide antenna, effectively confusing the computer inside the radar gun.

Perfectly legal in most states. Some radar devices have been outlawed because they transmit scrambling radar beams back to the waiting law enforcement vehicle. The Phazer, however, reflects a portion of the signal plus an added FM signal back to the police car. This, in effect, confusing the waiting radar unit. Best of all, unless you are a resident of California, Minnesota, Nebraska, Oklahoma, Virginia, Utah, or Washington D.C., using the Phazer is completely within your legal rights.
