Radar detectors are great for radar but worthless against Laser. Laser is instant on/instant off and has a very small beam thus if your detector goes off it is just telling you that you were just busted. I have run tests and unless I was pointing directly at the detector it never made a peep. When I was in traffic I never gave a warning to a person if I saw they were running a detector. I figure it has given them plenty of warnings already. And contrary to popular belief it really is all about safety and nothing to do about revenue, at least from the officer's viewpoint. I spent 4 years on the fatal team, that will slow you down.
To the OP I also would talk to the court, with your record it will most likely be reduced.
