Okay this is what I've discovered tonight.
My Beltronics 985 doesn't pick up photoradar in Calgary, AB Canada (apparently we use stalker 35.25GHz multinova) and so I went to buy to an escort X50 and found that it at the very least was able to catch photo radar and give me warning. The Bel 985 doesn't go off until well after passing the photo radar van whereas the x50 was able to for the most part catch it in time. It always caught the radar when someone was in front on me.
Now... I don't know much about Valentine 1's other than the fact that ppl talk about them all the time.
Their laser performance is truly amazing from what I've read but how about K and Ka?
I am looking for super range with minimal falsing and I want a company to stand behind their product. My understanding with Belscort is that they aren't too great in quality consistency and service is crap.
