i have a v1, and its never let me down, i regularly do dubble the posted and more and ive always had enough time to slow down.
ive owned 3 other detectors, and the passport was as good in range, but lacking on info.
the arrows are amaising, you pinpoint regular hot spots around your daily drive the very first time, and it always let me know what is something to look out for.
i was on about a 3 ticket a year schedual, then i got a v1, and havent had a ticket in 3 years now.
i feel like im hunting the way you get information, you know how intense, where it is commoing from, and how many signals in the area as well as the most likely threat.
if i had to pick a down side, it would be the size, but it really isnt that big, and even if it was 600 or 800, i would still say that it is worth the extra money over the other detectors
