Uniden - R4BLK Radar and Laser Dectector - Black

Great detector but if you're you like arrows then spend the extra and get one that has them.

The radar signals on the highway are very accurate.

Was a great radar detector for awhile... now it turns off by itself and you dont even know it has..

I needed to step up to a modern radar detector (RD) to replace my still functioning but outdated (lacking frequency blocking ability) Beltronics Vector 955. Over the last 2 years of my due diligence, I physically tried out a Radenso DS1, the Uniden R7 and the R8. Each of the aforementioned options had their own pros and cons but at their price points at the time of testing, I could NOT justify keeping them over my old RD that basically did the same but was just much louder because it does not allow for frequency blocking on newer vehicles. At the price point I was able to acquire my Uniden R4Blk in 12/2024, I have not had a single reason (read: con) to question my informed purchase decision. I won't bore you with the specs, you know what they are (or should before buying it). As an experienced RD user for over 15+ years, this firmware updated, arrowless UR4 is as quiet as one can ever hope to use. In our extensive California, Nevada, Idaho, Oregon travels, the Ka band and laser notifications are THE only warnings that we need to heed. In our most recent 3k+ mile round trip through the aforementioned states in 06/25, this dialed in RD was on point throughout and blissfully quiet otherwise. The quiet part is where I find the most value. NO ONE wants a RD that is constantly chirping for unimportant warnings. It again accurately warned across blind turns, blind hills and on long, long straight aways. I specifically noted a 3+ mile Ka warning out on the desolate I-95N in NW Nevada. To any RD user, arrows should not matter (save $100+ by not having them). You should be so in tune with the RD warnings that are important for your route(s), that you instinctively check your speed (read: brake no matter your speed while simultaneously checking your actual speed limit). That is all a RD is supposed to do. It is a tool to give you a chance to check your speed before getting popped for speeding. I can and do give my unequivocal, road tested approval to this particular model for its accuracy, firmware update frequency, PRICE POINT and reliability. P.s. This UR4BLK unit was my specific target model due to the fact that the matte black construction absolutely keeps the glare down from every angle. A big improvement over my other RD that has a silver/chrome top side that at times can be "blinding." P.s.s. Combine this tool with the Waze app. and you can turn the odds of road travel without speeding violations to your favor. ALWAYS STAY VISUALLY AWARE!

Excellent detector! Have had for a few months now. The Auto mute mem is a nice upgrade from the r3. Comes set out of the box to alert at full volume at first, and then drops the volume. Have picked up Ka band from 4 mile in good conditions!
