I have a V1 that is not even 2 months old it is the 3.826. Today I went to the city to pick some stuff up well there is a grocery store in the town that I travel by to go to the city the store has K band doors my V1 picked it up like usual on the way out. I usually get 500 feet of distance. On the way back, I get usually get 1000ft and I did not get a warning at all so I was like WTF :shock: , I turned around and went into the parking lot usually the detector goes full strength, but I got nothing. I turned on my X-50 that is spec mode and it alerted full strength 24.122. I then turned off both and turned back on the V1 and it alerted. I am pissed I rather have my X-50 say self cal and Service Required than not no my detector is working until I find out with a ticket. I can understand a detector drifting out, but this thing is practically brand new. I hope no one else has this problem, but I wanted to make every body aware of the issue I just had.
