Well the V1 is a nice detector, but I am going to return it.
It did not give me as much warning on Ka as my original passport 8500 does in the following sitution:
The officer is ahead shooting the rear of cars after they pass by. In this set up the detector needs to alert as soon as possible BEFORE you get to the LEO's location. This is simiular to the Ka photo radar setup that clock you as soon as you pass that other member were recently talking about in the thread about the new GOL test. The V1's range is not as good as my original 8500 in this encounter. The V1 was excellent with Ka when the source was in front pointed my direction and if it was off to the side.
The V1 is hands down the best K band detector I have seen, the V1 has a very slight edge on the X50 for K band, but not a significant difference. However the V1 is annoying when it continues to alert with a rear arrow after passing my grocery store K band door.
One weird thing I noticed about the V1 when I encounter 2 LEO's running constant on K band side by side, I would get a Ka alert when i get close to them. This happened more than once.
Maybe one day a detector company will make a detector that detects Ka as good as the original 8500, K band as good as the V1 or X50, and POP like the RX65 or V1 all in one detector.
Until that detector comes out, I'm gonna run with 2 detectors. I will use the original 8500 for Ka and since I still have my X50 I will use it for K band.
