I live in Nashville, TN USA.
May 9, 2005 I got ticket for doing 66 in a 45 (southern Briley Pkwy in Nashville, TN). I was in pack of cars, but unfortunately, I was in front and ran into a speed trap. Now this my second ticket in two months. Not good.
I bought a Cobra XRS-777 on May 10, 2005 at Wal-Mart in Hopkinsville, KY. This is my first RD. My kids live there and my daughter had a soccer game that day. I was feeling a bit paranoid about driving because I know that lately the cops have been cracking down on speeders in Nashville. Not only that, but I figured my luck was going to run out pretty soon on the interstate between Nashville,TN and Oak Grove, KY.
I wrote Cobra an e-mail asking about this RD because it is not listed on their web site. I told them that it looks to be a relabled for Wal-Mart XRS-9700. The reply it received back was that I was absolutely correct. Cool... now I know what it is.
It seems to get a lot of POP detections that I can't find with my eyeballs. I leave POP on however because it has alerted for POP a couple of times and then bam, I see a cop. It has picked up a few door openers, but now that I learning where these doors are, I do NOT ignore them. I just make sure I am going the speed limit as they can mask a real Radar gun.
The night I bought it, I was heading back to my apartment (again on Briley Pkwy) and I was alerted to a Ka so I slowed down. Sure enough, as I came around a bend there was a cop on the side of the road facing the same direction as traffic. The alert happened about 1/2 mile from the officer. About a mile down the road from the first guy was one that had someboy pulled over.
Yesteday I was traveling up Briley Pkwy in Nashville. I was going the speed limit because I know the locals have been patroling Briley pretty heavily lately and I was getting some POPs and Ka alerts. As I came around a bend my detector went full alert on Laser. I about jumped out of my skin when the laser alert went off. He was sitting right there and if I had been speeding I would have been nailed. No dought about it. Now I know the locals use Laser in Nashville, TN! I am not sure what good laser detection does since the officer surely would have nailed me if I was speeding.
I travel to Hopkinsville, KY to visit my kids every Wednesday and every other weekend. It's about an hour drive each way and most of it is spent on I-24 running between Oak Grove, KY and Nashville, TN. Wednesday night I was coming home from dinner with the kids and I got a K (or Ka, don't remember) alert that went to 2 bars. I know this is real because most of the time I just get one bar even if the threat is real. I slowed down and about another 1/4 mile down the raod I saw a state trooper in the median. I was still going about 4 over but he didn't bother me. Everyone else was going about that rate of speed too.
I know that POP isn't really that useful with this unit, but I think it would be a mistake to turn it off. I wish that it was a little more sensitive in the threat level department as well. Most threats show up as just one bar.
Overall, I think it was a good thing to get this RD.
Edit: I have this detector mounted on the windsheild, just below the rear veiw mirror.
