Radar detector detectors
“their new spectre3 radar detector detectors will alert a an officer that their is a radar detector nearby and can fine tune to figure out where… There are atleast 85 OPP cars that I know of in ontario that have them that was a year or two ago… remember detectors emit detectable frequency leakage in their operation, ocilisoscopes. This is detectable with these newer guns.”
Also the law says it is illegal to not only use it but also to just have one:
HTA 79 (2)
Speed measuring warning device prohibited
(2) No person shall drive on a highway a motor vehicle that is equipped with or that carries or contains a speed measuring warning device. 1996, c. 33, s. 12.
