TO BE LEGAL THE UNIT MUST NOT TRANSMIT ANY RADAR SIGNAL.  THE ROCKY MOUNTAIN RADAR UNITS DO NOT  TRANSMIT ANY ILLEGAL RADAR SIGNAL!   IT HAS A MILITARY TYPE COUNTERMEASURE DOPPLER FM CHIRP (500-9,000 Hz) THAT ALLOWS THE INCOMING RADAR SIGNAL TO MERGE WITH THE FM NOISE AND IS REFLECTED BACK TO THE RADAR GUN.  THIS  CAUSES A ZERO MPH READING AND  HAS AN EFFECTIVE RANGE OF 4 TO 6 TIMES THE RANGE OF THE RADAR GUN.  WITHIN 150 FEET OF THE POLICE RADAR UNIT THE INCOMING RADAR SIGNAL WILL PUNCH-THRUGH YOUR DEFENSE,  SO DRIVERS SHOULD ADJUST THEIR SPEED ACCORDINGLY. 

THE  ROCKY MOUNTAIN RADAR AND LASER SCRAMBLERS TRANSMIT A LEGAL (SPECIALLY MODULATED LASER BEAM)  WHICH CONFUSES THE COMPUTOR IN THE LASER GUN UP TO THE MAXIMUM RANGE OF THE GUN WITH NO PUNCH-THROUGH EFFECT WHEN USING LASER.
