my Bel 985 radar detector screamed "Laser Alert" this morning while i was heading down the highway, yet my Blinder M20 stayed silent. any thoughts? i saw no patrol cars anywhere in the area, but that doesn't mean they weren't there. could it be the Blinder is not working? i know a few weeks ago it went off and my detector didn't. that made more sense to me, as the detectors are not the best "sniffers" of Laser. the unit powers up from red to green LED, and the speaker does emit it's tone, so i am not sure where else to check regarding it's functionality.
