Of course very unscientific but I bought a V1 to potentially replace my 3 year old X50. Found a speed sign on the highway shooting k band and decided to do some testing. First I ran the V1 in all bogey mode and noted where I got the first alert heading toward the sign(facing me). Went a couple of miles to the next exit and came back from the other direction and did the same. X50 was not mounted or powered while doing this.
Turned around, took down the V1 and mounted the X50 in the same spot on the windshield set to Highway mode. The X50 actually alerted approximately 60 to 80 feet before the V1 did both heading toward the sign as well going the opposite way the sign was facing.
V1 did continue to alert about .2 miles past the sign going the opposite direction than the X50 did though.
I'm a little surprised and disappointed. I'll do more testing but maybe sending the unit back afterall.
