When I was a police officer, I used my V1 to find the multiple-bogey areas in town. Then I hid in the “false alarm zone” and ran my radar and laser guns.
I can honestly say that the majority of the prey I caught had some sort of other detector, if they had any at all. I caught only one person with a V1, and that person, in his rush to get home, forgot to turn it on.
To this day I use that V1 in my own driving. It’s definitely is worth having.
