While on a long drive back from vacation I thought of these .
Do they even make them or are they completely illegal now ?
I remember that some States banned them .
just did a quick search and yes they do, they even still have the "whistler". Was on the road for many years but never invested in this toy...Cincinnati Microwave made a killing on these things...they made the radar guns, then the radar detectors, then they made detector detectors, then the laser gun, then the detector...back in the (Smokey and the Bandit) days guys would use the common ice fishing flasher, mounted on the dash with transducer mounted in the grill to mess up radar (allegedly), oh yea, forgot the jammers...but being tired, retired, worn out, and get a nose bleed going over 70 anyway, I probably don't need one now either.
In Wisconsin they are legal. Speed traps laser are always used, and like mentioned before, it will detect a laser, but it's too late when detected and your busted. It could help you if the officer continues to ping you with the laser waiting for you to get to a certain speed. That gives you time to slow down. They do help tho, many times the officers laser gun is actually in the trunk of the vehicle, so them using genrap radar would be more common.
this might be your best answer
I think the best method is to find another driver who has more cajones than you and stay 1/2 mile behind him (her)
