Agreed. First rule of using jammers, immediately slow down to the posted speed limit then turn them off (called Jam Then Kill or JTK). NEVER jam them right to the gun....cops aren't stupid and you're just asking for trouble. Most jammers have an automatic shutdown, but most people do it themselves and can JKT much quicker with much less suspicion. Five seconds is quite a long jam, considering laser guns can get a reading in less than a second.
