The Uniden R8 debuted at CES 2022 because the improve to the favored R7. Just like the Uniden R4 (the improve for the R3), the R8 is constructed on a brand new platform with two Low Noise Amplifiers (LNA) to extend detection vary. Uniden additionally added an Auto Mute Reminiscence function and an Auto Sensitivity mode to the R8, each of that are handy whereas driving in heavy visitors.
As of this writing, the Uniden R8 retails for about $700 on Amazon, whereas the R7 retails for round $470 on Amazon. Is it value spending the additional cash for the R8? On this evaluation, I hope to assist reply that!
How I Use My Uniden R8
The Uniden R8 sits alongside items from Escort, Cobra, Radenso, and K40 in my assortment of radar detectors. I additionally personal a Uniden R3, R4, and R7, the latter of which I actually like due to its giant show, directional alert arrows, and Ka Slim segmentation choice. It’s not simply me both. When looking by the Radar Detector discussion board, I all the time see lots of constructive suggestions on the R7, so it could appear the R8 has massive sneakers to fill.
I’m continually navigating stop-and-go visitors right here within the Detroit metro, notably on most important roads like M10, I-696, I-94, and Telegraph street. One second, you could be crawling alongside, after which you’re again as much as freeway speeds. I rely closely on the R8’s Auto Sensitivity mode, one of many unit’s finer upgrades over the R7. Basically, it’s a speed-dependent mode, robotically switching forwards and backwards between Metropolis and Freeway modes at a pre-set velocity. Within the settings menu, search for “Auto Metropolis Velocity,” the place you’ll be able to set the R8’s switching level between Metropolis and Freeway in 5 mph increments between 10 and 60 mph.
Complimenting the Auto Sensitivity mode is the simple vary and reliability of the Uniden R8, a key attribute of the unit’s twin LNA design. On my each day drive within the Detroit metro, it’s not unusual to see the Michigan State Police, the Oakland and Wayne County Sheriff’s deputies, and different native police patrols, relying on what suburb you’re going by. All run a mix of constant-on or instant-on Ka radar (on the time of this writing, the State of Michigan has a contract with DBA Stalker Radar & Video).
With the visitors quantity and curved roads across the Detroit metro, officers don’t really want to cover. With generic, run-of-the-mill Ford Explorers and Chevy Impalas, regulation enforcement round right here blends in like the colour yellow at a pineapple competition. I’ve had speeders fly round me on I-696 like I used to be standing nonetheless. A couple of moments later, my R8 picks up a Ka band, and a shiny pink ahead arrow lights up the show. And guess who’s pulled over simply the opposite aspect of the exit ramp?
When you reside in an space with heavy visitors and a powerful regulation enforcement presence, the Uniden R8 is a superb alternative.

Uniden R8 In-Depth: What It Provides
The R8 comes with a 12V DC energy wire with an RJ11 connector, hook and loop tape for dashboard mounting, and an proprietor’s handbook. Included are two totally different windshield mounting brackets. There’s a bigger single suction cup bracket and a bracket with two smaller suction cups. Uniden features a carrying case with a Neoprene sleeve too.
The Uniden R8 features a built-in GPS, which determines your geographic location after which identifies “set frequency areas” in your space from a database. Set frequency areas usually embrace issues like pink gentle and velocity cameras.
New Platform
The Uniden R8 is constructed on an all-new platform, giving it a bonus over the R7 when it comes to detection vary and obtainable options. Relating to the R8’s platform, comparability is a automobile platform, or somewhat, the structure and chassis. Each automobile has a “platform” on which it’s designed, engineered, and manufactured. Think about the distinction between a automobile constructed as we speak and a decade in the past. The brand new automobile can be safer, extra fuel-efficient, journey and deal with higher, and have extra tech options. The up to date structure, or platform, permits such issues to return to fruition.
The identical analogy applies to the Uniden R8 and R7, just a bit smaller.
This new platform permits the R8 to have issues just like the aforementioned Auto Mute Reminiscence operate and upgraded twin LNAs to detect radar sources from farther away. Likewise, the R8 has a laser gun identification function and may detect Gatso radar utilized by the most recent velocity cameras. These are variations between the Uniden R8 and R7 and will assist you justify the worth bump.
If you wish to geek out, learn by the proprietor’s handbook of the R7 after which the R8’s handbook. When you discover different refined variations that make the R8 stand out, it’s due to the brand new platform.
Radar & Laser Safety
The Uniden R8 will provide you with a warning to X, Okay, and Ka radar bands and laser (LiDAR) weapons. I’ve X bands turned off, however the Downriver communities south of Detroit do use some Okay band, so I’m hesitant to have my R8 ignore Okay band outright. Whereas you could have the occasional Okay band false with the R8, the Auto Mute Reminiscence function shortly saves them.
Just like the R7, the Uniden R8 has a Metropolis and Freeway mode. In Metropolis mode, X and Okay band sensitivity is diminished to forestall false alerts, whereas Ka bands keep at full sensitivity. In Freeway mode, all bands go to full sensitivity to provide the most response time on the open street. You may additional optimize the R8’s sensitivity ranges by the Superior Mode. Much like the R7, you’ll be able to modify the Rear Steadiness of the R8 within the settings menu.
OLED Show & All Risk
The R8’s OLED show is much like the R7 and can present the frequency when a specific radar band is detected. The corresponding sign power indicator strikes from inexperienced to yellow after which to orange and pink, relying on how shut you’re to the menace. Audible alerts are issued concurrently, with the tones turning into extra fast the nearer you’re to the radar supply. Much like the R7, the Uniden R8 exhibits which course the menace is coming from through a stable pink arrow.
You may set the R8 to announce the kind and frequency of any radar bands you encounter. In that case, it would additionally announce the course. There are three totally different alert shows to choose from within the settings menu, so mess around and see which one you want greatest (this can be a refined improve because the Uniden R8 provides yet another alert show than the R7).
After all, no Uniden radar detector could be full with out the All Risk function! Though the manufacturing unit setting for that is off, it’s one thing you wish to swap on straight away. With the All Risk engaged, the R8 will concurrently detect as much as 4 radar bands, displaying every of them visually on the OLED show. The strongest sign is designated because the precedence and can seem entrance and middle. As much as three different indicators can seem on the left aspect of the display screen in what resembles somewhat digital chart (for lack of a greater phrase). This digital chart exhibits the person radar band, its sign power, and course.

Segmentation Filters
You may experiment with the Okay and Ka filters within the settings menu, together with a segmentation filter. To entry the segmentation filters, change the “Mode Show” within the settings menu from “Primary” to “Professional.” For Okay bands, the R8 provides you three segmentation filters: Vast, Slim, and Prolonged. Ka bands have two segmentation filters, Slim and Vast. The R8’s Ka Segmentation enables you to customise a Ka band sweep from 9 totally different filtered settings.
I like Slim segmentation as my R8 scans just for U.S.-spec weapons, nor will it span your entire frequency vary. This cuts down on the false alerts and will increase the R8’s response time, which is useful in an space the place instant-on Ka band radar is current. The R8 also can detect POP transmissions, MRCD, MRCT, RT3, and RT4 (RT3 and RT4 being the separate frequency ranges of Gatso radar).
In alternate for the upper value of the R8, you’re alerted to all kinds of radar sources, from patrol automobiles and velocity traps to visitors cameras and different picture enforcement units. When warning you of an upcoming pink gentle or velocity digicam, the R8 will present visitors gentle or digicam icons and the corresponding distance (in toes) to the alert.
Mute Reminiscence & Consumer Marks
If you encounter an alert you recognize to be false, press the Mute/Dim button on the entrance of the unit or the Mute button on the ability wire. You’ll then see “Mute On” seem on the show. Press one of many buttons once more to save lots of that GPS location and frequency to the R8’s reminiscence. If you cross that location once more, the R8 will show the alert and the frequency on the OLED show, but it surely received’t make a sound.
Consumer Marks (additionally referred to as “location marking” in radar detector lingo) work equally, however you’ll use them for areas with a identified, recurring radar supply. When passing by this space, press the Mark button to save lots of that location. The R8 will difficulty a voice immediate the subsequent time you’re close to that saved location. One factor to notice: you can’t save a brand new location if there’s a earlier Consumer Mak inside a 1,600 ft radius (I’ve by no means run into a difficulty with this).
Reminiscence Quota
The R8’s up to date platform helps a Reminiscence Quota function, which the R7 doesn’t have. Reminiscence Quota enables you to set the person variety of Mute Reminiscence and Consumer Marks. In whole, the R8 can save as much as 2,000 factors between the 2, however you’ll be able to allocate that a method or one other in 50-point increments.
For instance, I’ve my Mute Reminiscence set on the most of 1,750 allotments, that means I’ve 250 for Consumer Marks. I are inclined to encounter extra Mute Reminiscence areas right here in Detroit, so I need the best allotment potential. Though, if I ever want extra room for Consumer Marks, I might drop that allotment for Mute Reminiscence in 50-point increments.

Is The Uniden R8 Price The Cash?
It is a legitimate query, contemplating the Uniden R8 is among the costlier radar detectors available on the market. Finally it comes all the way down to what you’ll realistically want and use in your each day drive.
In case you are engaged on a devoted finances however are nonetheless occupied with a Uniden radar detector, each the R3 and the R4 are good choices (this useful information will clarify the distinction between the 2). The R3 and R4 are somewhat smaller in dimension and have a number of much less options however nonetheless provide glorious detection vary and reliability. Though I really like my Uniden R8, I nonetheless use my R3 and R4 right here in Detroit.
When you don’t thoughts spending the cash, the R8 gives you essentially the most situational consciousness with the least quantity of effort. That is what I admire most concerning the R8. With the directional alert arrows, voice notifications, Gatso detection, and All Risk function, I’ve a good suggestion of what’s occurring round me. Then, with the R8’s new Auto Sensitivity mode, I don’t have to fret about messing round with something whereas I drive.
For extra perception, flick thru the Radar Detector discussion board, which has a whole dialogue part devoted to Uniden radar detectors. There are tons of individuals on there (myself included) who may help you make the very best determination.
In any other case, if you’re offered on the Uniden R8, you’ll be able to seize it on Amazon for about $700.
