The new Uniden R8 is Uniden's latest dual arrow directional radar detector which provides directional information.

In our Uniden R8 review, we found the radar detector's performance is significantly improved making the Uniden R8 the most sensitive and longest range detector we've ever tested.

Having more than 16 times the capture distance of a police radar gun, the Uniden R8 provides performance often exceeding all other manufacturers' top performing radar detectors at considerably less money making it a very good value.

The Uniden R8 has the largest color display of any radar detector allowing it to display a wealth of information at the same time, including up to five radar encounters simultaneously, time of day, speed of travel, and direction of travel. Uniden R8 accessories include a hardwire kit for those interested in eliminating the use of the Uniden R8's cigarette power adapter. You can read a detailed Uniden R8 review.

5 of 5 Uniden R Series August 6, 2022
Reviewer: Kelly Griffin from Pottsville, AR United States  
Roam the open roads, have been running the R7 for the past few years. Once you understand how to set them up, you can't beat'em. The R8 with the new LNA's has a bit more distance that sometimes gives you an edge. Really like them both, for me they work better than anything I'v ever owned & I'v had a lot.

5 of 5 uniden r8 July 13, 2022
Reviewer: ronald miller from montgomery, PA United States  
one  of the best detectors i have ever owned, still picks up a lot of signals though, like banks and business, but guess you have to live with that. it did seem to eliminate most of the signals from colision modes on a lot of new cars. so far so good. a little pricey though, but i guess you get what you pay for.  keep up the good work. r.m.

5 of 5 The new Uniden R8 July 7, 2022
Reviewer: Steve Welch from Fayetteville, AR United States  
Hi my first Uniden radar detector. My favorite was the Valentine1 Gen 2. Love it specially with the app nice range picking up a state Trooper mile and a half out. I got to compare the 2 love them both together but the Uniden it has much more add ins yes it picks up far enough haven’t had a chance to see how far but over all once you tune it in nice only thing is wish they had an app to control it make things easier. I live in Arkansas so we don’t have red lights cameras. But yes I am glad I ordered it. Recommend to a friend yes. My friend he had a Valentine1 Gen 1 I talked him into buying the Uniden R7 he didn’t need the extras he really likes his so yes Uniden nice radar detector. Please make an app so we can access the setup menu like run in dark mode. Also the R8i think you can add on laser  jamming.i really like it talks to you not the same old beep beep from the Valentine1. My next radar detector is for my Harley SE2 V Rod. 👍🏻Up for the new Uniden R8.

5 of 5 R8 vs R3 Performance June 30, 2022
Reviewer: Peter A.  
I need to test drive this new R8 performance since I have seen the performance of my R3 for a much longer time. However I am really impress how RadarBusters communicated with each customers. I give them 5 stars. I am also satisfied with my R3 hoping that this R8 is much better and hope it has a new chip with faster processing of its functionality.

5 of 5 Uniden R8. The best of the best. June 30, 2022
Reviewer: No such thing as too much horsepower from Kingsport, TN United States  
Uniden has done it again and thanks to radar busters they’re customers are getting them into their hands very quickly.
I have 3 R7’s and are very happy with them, however the R8 just takes the performance of those detectors and just steps it up another couple of notches. If you are serious about your driving and like to enjoy it to the fullest, then you need one of these for every car or truck that you own.
Radar Busters will be sure you are one of the first to have one!
