The Passport 8500 X50 tested the best (in the tests I put the most faith in) in around the corner Ka, and that is my biggest concern. It also has an expert meter that shows multiple signals and their strength. The V1 doesn't offer that. I can tell where the cop is from watching the signal strength effectively, so the arrows don't impress me as much as others. The new one has some nice features, but exactly the same sensitivity to K and Ka signals. I also paid $260 for mine--shipped, brand new. You won't go wrong with the V1, 8500-or 9500 Passport, or the top of the line Bel. For my money, I picked the best. As the Air Force pays me to be radar savy--and I have access to experts in the field, I know a bit about it. :thumbsup:
