With all the talk about which jammer is best, I think it's important to recognize the laser jammer's function as a detector as well. Laser detection from a windshield-mounted detector is precarious at best and by the time it goes off it may be too late to hit the brakes. With jammer transceivers mounted in the grill where the officer is aiming and plenty of Veil on the front of my car, even if the jammer isn't a miracle worker, it will still notify me of a laser hit and I'll likely have a lot more time to hit the brakes and avoid a ticket than with a windshield-mounted detector alone. Keep this in mind when scrutinizing close punch-thru numbers and other test data. And don't skip on the Veil just because you have a jammer!
