V1.
The arrows are indespensible. Makes the driving experience much less agitating when you know you've passed the threat.
Interesting story:
not so long ago the laser warning went off but luckily I was travelling just at the speed limit. I looked in the mirror and I could see a large crown vic type car 5 cars behind. Then the laser went off a second time. Yep Porsche profiling! I was surrounded by Hondas and Nissans etc. This went on for about five minutes until
I saw the cop accellerate and zip past me. I guess he figured out his cover was blown. A half mile down the road and He's pulling over BMW.
The V1 has consistently tested as the best performer at picking up laser from a trailing vehicle, which is
much harder than a stationary laser.
The remote readout also eliminates tail gaters and doesn't attract attention from
cops parked on the side of the road waiting for a target.
