Our testing is open to all invited participants. It’s common industry knowledge. We do this every year. The dates were posted to our internet site of www.radarsignals.net for over three months.  We responded to those expressing interest in attending.  Some companies don’t like to be tested, especially with certified police officers operating the equipment. We publish testing of legitimate products from reputable manufacturers. We don’t include those who have “borrowed” or “knocked off” a legitimate product hiding behind international borders.


As always Laser Blinder, www.blinder.dk Leon Gruner, accepted our invitation.  Blinder is Denmark made with obvious attention to durability and to performance.  Blinder has been at SML field tests for over ten years.  Unfortunately,  other laser counter measures have apparently copied Blinder’s patented,
successful product design without
permission with the attitude of “prosecute me behind my border and good luck.” If they do this to Blinder, think  what they will do to you as a customer. Our E.E. engineer Dave Adams verified pulse rates of each laser gun. John Turner of 1st Radar Detectors, www.1stRadarDetectors.com came from Colorado with the new Blinder M47 mounted in the grill of his truck.   Blinder products are designed for small and large vehicles. M47 has four front mounted transponders to cover large SUV surfaces.  In cars, you only need two.  See Blinder’s web site for specific product features. Leon was bold. He said, “test it against every laser gun you have.”  Jamming or attempting to jam a police laser gun is not against any federal law. Some states do ban them, so check first. We will not test illegal products banned by the federal government meaning alleged radar jammers.


We used the same nine laser guns used in the laser reception and reporting test against the Blinder mounted on John’s truck, a motorcycle, and a Mustang. We set cones at 1,000 feet and 500 feet. The test vehicle drove at 30 mph.  Faster speeds are to the advantage of Blinder. The test vehicle counted down, “three, two, one” at each cone.  The officer then fired the laser gun.  Graphs are great, but not needed here. In the 162 runs against all lasers at  1,000 ft, and  500 ft. cones, by the truck, the Mustang, and the motorcycle, all with a Blinder mounted, Blinder successfully jammed each laser gun, each time. We are still scratching our heads on how Blinder did it.
