Frequently Asked Questions 

The 

Rocky 

Mountain 

Radar 

model 

RMR-8RDS 

detector/scrambler  is  designed  to  give  you  radar  and  laser 
detecting and scrambling from the front and rear of the car.  

Can I test it with roadside trailer radars? 

The  trailers  you  see  on  the  side  of  the  road,  that  show  your 
speed, are not legal to use to write tickets. They do not contain 
the  sophisticated  sampling  computers  that  are  in  police  radar 
guns.  Since  our  units  confuse  the  computer  and  there  is  none, 
they will not work reliably against the trailers. 

Can the police detect it? 

The  radar  and  laser  scramblers  do  not  have  RF  emissions  and 
cannot be detected.  

What states are they legal in? 

The  Rocky  Mountain  Radar  scramblers  are 

not

  legal  in 

Colorado,  Utah,  California,  Nebraska,  Oklahoma,  Minnesota, 
Illinois 

(unless  the  scramblers  are  unplugged)

  and  Virginia. 

The  Rocky  Mountain  Radar  detectors  are 

not

  legal  in 

commercial vehicles in most states. Use caution in these states.

What is Punch-Through?

 

The signal reflected by the car gets stronger the closer the target 
is to the radar gun. The Rocky Mountain Radar scrambler uses 
the  radar  signal  as  a  carrier  and  reflects  it  through  a  high-gain 
antenna.  It  will  work  only  as  long  as  the  scrambling  signal  is 
greater  than  the  signal  from  the  target.  Punch-through  is  when 
these signals are equal or within 50-200 feet. 

What is the effective range? 

The radar scrambler works at four to six times the range of the 
radar  gun.  The  laser  scrambler  is  effective  at  more  than  two 
times the Lidar range.             
 

Important information:

 

 

When driving in states that ban scramblers – unplug 
the front and rear scramblers. Detectors are legal in all 
states except Virginia and Washington D.C. With the 
scrambler off, this unit is only a detector.
