I decided to try my V1 mounted vertical against the low powered k-band photo radar DPS units across Arizona on my way across the I-10. In past testing mounted normal (horizonal) on the dash I was getting 2-3 seconds average before ramping up next to the DPS unit. In a vertical mounted position I am getting much better distance at least 50% improvement at an estimated 5-7 seconds. Any one else give this a try? I had 5 encounters coming home and all were a noticably longer alert than mounted horizontally.
