Very informative review. Thanks!i have a passport 8500 x50 and i'm pretty happy with it
my buddy and i did a comparison test on a drive down from chicago to atlanta earlier this month (2 different cars w/ communication via 2-way radios). some quick observations...
- x50 is more sensitive to KA and K band directly in front
- v1 is FAR more sensitive to the rear of the car (though this may have something to do w/ the fact that my x50 is mounted very high while his v1 is mounted in the center of the windshield)
- x50 false alarms much less
- v1 arrows are very handy to have
brand new, the price difference is about $100 ($320 for the x50 vs $400ish for the v1). if you do a lot of high way driving, i'd probably go for the v1. but if you're in the city mostly, the x50 will more than suffice and false alarms much less
