You should try using a radar detector. They work better.
I've been told that laser's have trouble picking up moto-cycles because there is no large flat surface to bounce off. Anyone ever been tagged by laser. I have - but it was in my cage.
The locals recently ran a "speed enforcement" using laser. It was up in Santa Rosa on a freeway. Because of the need for precise aim required with laser, they had to use a stationary officer to tag em and others to pull em over. Not many depts use laser because it is so picky about reflective surfaces and aim etc. I have had a couple laser hits on my detector (escort 8500 x50) but no cop cars around.
