Radaf also relects off of glass, metal wheels, etc..... (I went to Radar school when I was a cop)

Since you been there, what about is the effective range, or how far out can you get an accurate lock?

Depends on the Radar or if its Laser. Plus the speed of the zone your doing.

I think there was a mythbuster episode on this, that was offcially BUSTED

they did this stuff on myth busters. tried like 10 differnt things, even a giant spining radar deflector of doom thing on the roof of the car and wrapping the car in tin foil. nothing stopped it.

Wouldn't Tin Foil reflect it?

reflect what?....isnt radar basically sound waves that bounce back?...........anyways V1 trumps all.....I had a Bel vector and it was pretty good....but the V1 is MUCH better....and those arrows and bogey counters are the shiznizzle

radars bounce off you licence plate not on the actual body!!!! people will do anything to make a quick buck :( BUYER BEWARE

its laser that they bounce off the plate....as long as its a flat surface thats when they use laser...a while back Car and Driver tested laser from the front on a bunch of new cars and on the Firebird it had almost no affect....no flat spot on the nose (they had no ft plate on it)

I thought I posted an answer to this, but I guess I fell victim to lag or something. Basically my answer was, depemding on style (hard mount or gun) and make/model of the radar, we could get reading up to a mile away. Identifying the specific car at that range is nearly impossible, tho, unless it'* the only one there.

And, a nifty fact, a lot of police will leave thier radar on even when they aren't actively looking for speeders. Everyone'* detectors going off helps keep the pack under control. And some of us thought it was fun to just hit the radar and watch all the pretty brake lights...
