Home > Consumer Reviews > Cobra XRS 9740 Ultra Performance 12-Band Radar/Laser Detector

I use Radar Detectors in every vehicle and I have all brands... The most important thing I want to say about this one is... It does NOT have that ever annoying BEEP BEEP that penetrates through your skull that forces you to mute the thing and then you forget it went off and see the source of the detection!! IT HAS A PLEASANT TONE (as pleasant as a tone warning you about a speed trap can be...)!! And it even slowly fades quieter... Oh... I LOVE this detector! I plan on replacing all my others with this model! On a side note.. it is also much moer light weight than others.. so when you hit one of those front-end killing pot holes thatare all over our great nation, it will NOT fall dramatically from you windsheild mount and cause you to swerve throught the highway lane....

I would purchase this Cobra again. I read all the reviews before buying and they were correct - great item. Once I learned the codes (exp: X) then I didn't panic. My hearing is going and like that it alerts me to emergency vehicles.

I've bought the product after reading many reviews and was one of the recommended ones, but it just doesn't work. Calibrating the Compass was an easy thing as if you follow the instructions carefully it will be done in the first go. Mounting on the windshield and taking it off every time when you park in a public garage for safety reasons, it won't just come off the clamp it is provided with, so basically everything you need to remove the whole thing and put it back again is really painful.

Now comes the actual part where it should warn the driver of any radars nearby and also when a laser gun is being pointed at you straight from a distance. It failed both the parts! No beeps for any radar even if the trooper's car is on the side of the highway. No beeps even if the laser gun is pointed straight at your car not even from 50meters.

All it does is giving unwanted false alarms and that's it.

The added feature, where it tells about the approaching emergency vehicle with the transponder on is also of no use and it gives the beep when the vehicle is right next to you.

I have had many radar detectors since I have been driving and the Cobra XRS 9740 is very impressive. I actually purchased two for both my wife's car and my truck. The day I recieved it I plugged it up, turned it on, and was attempting to install it on my windshield when it said "Ka Band Detected". I was wondering what button I accidentally pushed when I noticed a sheriff's car coming down the main road outside of my subdivision. The distance on mine is outstanding and my wife has had the same results as me. Some people have said it is difficult to program, but I found that it was extremely easy. Also it comes with a short coiled cord but I ordered a long straight one (item #420030N001) for my truck. My next door neighbor liked my XRS 9740 so much that he ordered him one and he loves it too. I have seen some of these one star reviews and just have to laugh! Radar detectors do not always work, or they work too little too late. Some police cars you pass may not have the radar on so don't assume the detector is broken. If you're the first or only vehicle on the road and a police officer aims the laser gun at you your detector will go ballistic, but you're still busted. A radar detector is not a free pass to speed, but a reminder to check your speed. Overall, I would highly recommend this product.

Bought this for my son. He says it works great. Thanks for the fast delivery, got it in time for Christmas.
