Radar/Lazer detectors are not illegal; the Radar/lazer detector/jammer is illegal and can be detected by the actual cop doing the point duty.
The most detectors are set to warn when receiving a signal in a frequency spectrum or the lazer, and yes, I agree that it is quite difficult to actual track a bike in traffic because the ‘LARGEST’ metal object will deflect the beam
The second problem arises when traveling in a city because there is FR signal of numerous items that will give a warning, my detector however have a ‘city’ setting that will actually discard these signals and will only activate the buzzer on an direct pulse.
The third problem is that the ‘audible’ signal of the unit is not always that loud and in my case the exhaust on 200kph makes quite a lot of noise and I will not always hear the buzzer, a earpiece is a possibility, but we all use the normal ‘car’ type unit on small bracket behind the screen
The wiring of these units are quite simple and normal DDC jack wired from the headlight unit is easy, just make sure it is protected and that no water will damage the jack when riding or when standing still
In SA most of the cops use the lazer/radar units together with a camera and pulse oncoming traffic and rather record a photo and most of the times do not stop the actual vehicle/bike, this is ok because we do not have front number plates, if they record a photo from behind [the traffic moving away from the unit],it is also ok, most of our guys do not have rear number plates [illegal] and will rather accept a fine [R 250, +- $35] from the cop when trapped in a roadblock on when parking,Im lucky, only one fine of 8 years
The solution, travel as fast as possible and do not stop for any cop, happy riding Guys!!!!!
