HP905 Compact Testing Results

“My Bottom Line Recommendation for the Blinder HP-905 Laser Jamming System”

As police laser enforcement is becoming more and more prevalent each day you need the protection of having a high-powered laser defense system to keep you ticket free.

And as of today, the Blinder HP-905 Compact has become my #1 choice.

Blinder has jammed all the performance of the larger and more expensive Laser Interceptor into a more compact and affordable laser jamming system that will save you money and time.

Because of the compact size of the laser jamming heads, the Blinder is much easier to install and is much less noticeable to law enforcement.

This review is based upon my 20 years in law enforcement as a certified police radar instructor and my 17 years being involved in the speed counter measurement industry.

We’ve had a discussion about the legality of laser countermeasures. There are no federal laws against the use of laser countermeasures, but many states have passed bans on laser countermeasures . We don’t test products violating federal laws meaning radar jammers. Before you buy, check local or state laws regarding this product. If you are stopped by law enforcement and they know you have a laser countermeasure, expect a ticket instead of a warning. Some laser guns, i.e., Stalker and LTI laser guns tell the operator they are being jammed. The two leading laser guns in the law enforcement market come from Laser Technologies Inc. and Kustom Signals Inc.

BLINDER Tests by SpeedZones

Test vehicles equipped with laser countermeasures were told to count down, “3, 2, 1” as they approached both the 1,000 foot and 500 foot cones. They were instructed to travel at 30 mph. Certified police officers and/or factory laser gun representatives operated the laser guns. They were told not to pan or follow the target vehicle, but to target the vehicle at the different locations. Aiming point was the front license plate.

  • J means the device jammed the laser,
  • NJ means the device did not jam the laser,
  • A means the device alerted to laser’s use.
  • NA means the detector did not alert to laser.
  • Passport/Escort/Beltronics call their countermeasure laser shifters.
  • Each device was given two runs at each laser gun.

Laser guns are increasing difficult to jam as laser gun technology moves forward. Honestly, if officers don’t get a speed reading while using a laser gun they simply move to the next target. There are plenty of targets!

We can’t report the results of LTI Model “S” as it does not appear on the 18 July 2011 listing, Conforming Product List, of the International Association of Chiefs of Police. The LTI TruCam and Laser Alley presented major problems as laser jammers had difficulty in jamming their guns. The Blinder M27 had the most success in jamming laser guns. Computer programs are available from the laser jammer makers to upgrade individual devices as new laser guns enter the market. As we have said before, the major announcements in the law enforcement market come from laser gun manufacturers. Expect to see more laser gun use in the future. Honolulu does not own a radar gun, only laser.
