I have received 6 speeding tickets in my life. 1 was without any detection device. 5 were with a radar detector. Radar detectors tend to give drivers a false sense of security and they typically end up getting more tickets than without one. My tickets were about 10 years ago. At the risk of sounding odd, I have never (and I mean never) received a ticket of any kind in a vehicle that included an operational CB. Why? Because when I listen to a CB, I know where every single possible thing is on the road; cops, wind gusts, construction, accidents, the works. Its real-time, grassroots, publicly supported, traffic-related news.
Radar detectors are great, but 9 times out of 10 they tell you AFTER you've been radared. You pop over a hill, your Ka band sensor goes nuts, and all that tells you is that you have already been pegged. Don't even worry about a detector that picks up laser. Consumer reports did a test on laser detectors and showed that many of them don't pick up the laser at all. The narrow beam is designed to shoot one small area of your car. Given the large frontal area of a vehicle, the chances that the laser will hit the detector are small.
But, with a CB, you know where every single cop, sheriff, deputy, city police, ambulance, traffic obstruction, fire, naked girl, truck stop, exit, and restaurant is for the entire state. A CB is like a radar detector, a news channel, and a GPS all in one, but unlike an automated thing, a CB is not only interactive, but its updated instantly and staffed by hundreds of knowledgeable people who are actually experiencing the road at that specific moment. You ask my GPS to find Smith Dr. and it looks for Doctor Smith. You want it to look up WalMart and it returns searches for Walgreens, Walter's flowers, ShopMart, Martin's house of sausage... or you just pick up a microphone and say, "where is the next WalMart northbound?" and you get five truckers who say "exit 225, turn left."
A CB is mostly for highway use, but local info is usually helpful and very specific. Radar detectors give drivers a false sense of security and it tends to bite you in the arse. Plus, radar detectors are only legal in about 29 states. CBs are legal everywhere.
