Radar detector detectors, RDDs, started with the VG-2 some fifteen years ago marketed by radar gun maker Kustom Signals Inc. It was looking for radar detector lo leakage at 11.55 GHz and used to enforce bans on radar detectors in 18 wheelers and in Virginia and Washington, D.C. to find radar detectors in cars. RDDs are widely used in Canada to enforce their strict bans on radar detectors. When found in Canada, the fine for radar detector use is up to $1,000.00 and confiscation. It is no longer made nor marketed. The VG-2 was replaced by the Spectre from Australia. It is marketed in North America by Applied Concepts, i.e. Stalker Radar. Thousands of Spectres RDDs have been sold replacing the old VG-2. If you drive a car in the United States you have little to worry about from the RDDs. If you drive an 18 wheeler and still use a radar detector you have a lot to worry about. Radar detector makers have constantly strived to make their detectors invisible to the VG-2 and Spectre. Many have made their radar detectors radar detector detector detectors detecting the detector detector before the detector detector can detect the detector. RDDs also leak microwave at specific frequencies and the cat and mouse game continued and some radar detectors would shut down when they detected a RDD. Once past the RDD, they would automatically turn back on. Some truckers buy inexpensive radar detectors throwing them out at a traffic stop fearing a ticket for radar detector use. Many municipal police departments have formed their own commercial enforcement divisions who purpose it is to enforcement commercial vehicle laws including radar detector use. This was the sole responsibility of state police agencies, but new laws now allow large cities to enforce commercial vehicle laws. Each year we test detectors against RDDs to see what new approaches are being made by detector makers to become invisible to RDDs. RDDs are provided by law enforcement agencies to SML for testing and officers operate the devices. Test vehicles begin at the 1,000 foot cone and drive toward the RDDs at 30 mph. If and when detected, the vehicle is told to stop and the detection distance is measured with a police laser gun set in the range mode. Each detector gets three tries and detector representatives are told to put their detectors in the RDD mode if applicable

Both the the Cheetah and the Tiger Lily PRS4STi used Beltronics STi detectors in their systems and were not detected by either RDD. The Beltronics STi was completely invisible to all RDDs. Whistler Pro 78 and XTR 690 had shortest detection ranges. Tiger Lily also offers models: PRS4-V-Valentine One with Blinder M45, PRS4-i-Passport 9500i with Blinder M-45, PRS4-E-Passport X50 with Blinder M-45.
