V1 arrows are a must have in my opinion. Just a couple hours ago I was driving home on a three lane highway with moderate traffic. All of a sudden I get a weak Ka signal on my V1. I check my speed and make sure to not be faster than traffic. The signal remains low for a bit of time, then fades, then comes back low. Finally signal is full strength for a second then goes very weak and stays there for a bit. If it had been a false alarm I should've been far past it by now and can usually watch a false move from forward arrow to side to rear arrow. But this signal remained on the rear arrow, after a few minutes of hanging fairly low in strength the signal got stronger until if was full strength. Within a few seconds a cop came flying past in the left lane and my arrows followed him to the side of me and then in front. If I had not had the arrows I probably would've dismissed the alarm as some strange false and never known a cop was sneaking up behind me.
