This review is from: Cobra XRS 9940 Maximum Performance 12 Band Radar/Laser Detector (Electronics)

I received this detector as an exchange for an earlier Cobra I sent in for service. Honestly, among diehard radar detector enthusiasts (yes, there are such folks) Cobra detectors don't have a great reputation. Cobra attracts a lot of first-time detector buyers with loudly-advertised "features" on their units. Truly, many of these don't have a real useful purpose.

Honestly, Cobra has made strides toward a better detector in this and the last generation of it's pricier units. Detection range is on par with other units you might find in this price range (or even a bit higher) with the exception of one of the widely used Ka frequencies. Several folks who've tested recent Cobras have reported a glaring lack of sensitivity to the 35.5 Ka frequency. This COULD be bad news for many folks out there as this is one of the more widely used of the Ka frequencies. However, if this is not in use on your commute, the Cobra 9940 is an acceptable unit for the daily commute. It's range is adequate although not on par with the the Bel Vector series which is priced in the mid to high $100 range. Whistler also makes a trio of detectors in this price range (XTR-690, XTR-695, and Pro 78) which tie the Cobra on detection of some frequencies and surpass it on others. Certainly, Whistler's units appear to excel at all Ka frequencies. If you can make due without the flashiness of the Cobra units, the Whistlers are certainly worth a look.

In short, this is an adequate detector for many drivers who don't surpass the speed limit by more than 8-10 mph. However, don't count on it for much more than that. But then again, a radar detector is just one tool to use in conjuction with one's own judgement when electing to surpass the speed limit.

3.0 out of 5 stars OK so far but compass is a pain!, July 5, 2008

So far I don't have much to complain about. I have had this unit for about a month. I do notice more advance warning than my old whistler unit. I have had the emergency vehicle approaching warning a few times when there was not emergency vehicle within sight and when there was one in sight I get nothing so I guess some of these bells and whistles are just that. The compass has had to be recalibrated 3 times now as it would all of a sudden only read SW. What's up with that?

So, as a radar detector I have been pretty pleased.

Cobra 9940 seems to work well for the bands it covers (at least I get lots of false alarms, probably due to cell towers and similar things), but I've been by at least 2 speed traps in NH where the gun has been up and on me without a response, so I suspect they are using newer technologies. If I had known, I would have shelled out more $ for a later model.
