Valentine is great! but it sucks when ur traveling 3 am in the road by yourself to go snowboarding up in the mountains. All the cops use instant on at that time so i got a ticket for going 83 in a 65. But the same place at 6 am, there are many cars so cops use constant on. I detected all 7 out of the 7 CHP's i saw and the fast cars that past me all got caught by 1 chp.
Valentine one works great when following fast cars at a long distance. i liek to follow fast cars so that the cop would spot them first with Ka and give me time to brake. I was just following a car that was going 100 mph and i gave him a good 1/4 to 1/2 mile just enough to see his tail lights in my wind shield. I was sure that i was not goign to get a ticket at any moment. V1 ftw!
