The theory behind this is that 5 seconds should be enough time to slow down, and by allowing the cop to get a reading on you after 5 seconds, s/he won't think you're running a jammer. Whatever. This is one feature I'd rather do without. I want my jammer to stay on and keep jamming. It's great fun to watch a cop repeatedly hit you with his laser gun, look at his gun as if it's malfunctioning, and hit you again to no avail. I just have to suppress my laughter when I drive by as he stares at me looking bewildered. I still have the previous gen. K40 laser defuser on my wife's car though (it stays on rather than shut off after 5 seconds). Over the years it's saved her about 7 times. Neither one of us has gotten a single ticket from laser since 1999, which is when we started using these wonderful devices. Our V1s have also saved us numerous times, but in my area they predominantly use laser, which suits us just fine.
