Why Do You Need A Radar Detector?

Driving is an activity that is regular and enjoyable, so fun that sometimes you find yourself driving beyond the speed limits. That is an offense that could get you a speeding ticket and no one like speeding tickets. But now, thanks to technological advancements, you can avoid speeding tickets entirely.

Radar detectors filter radar signals from different bands, alerting you to speed traps along your route. The better ones even mute false alerts, saving you the stress of frequently encountering unnecessary slowdowns. Of these “better” detectors, the Uniden R3 review is top-tier and using it assures you the best possible experience.

The Uniden R3 Review

The Uniden R3 is one that ticks all the radar detection boxes. It has an extremely long range that is better than what you’d find in other radar detectors. You get alerts about speed radars on most bands, long before you even get to the trap. Its coverage is equally impressive with detection from any direction, even around curves.

As a GPS enabled device, you get regular firmware updates that are easy to download and install to your device. It also gives you the ability to automatically lockout false alerts and mute radar alerts while driving under a specific speed. 

As for its drawbacks, the lack of directional arrows and its susceptibility to false alerts, are issues that are easily ignored and overcome. Especially in the face of its affordable price, as well as its immunity from detection in locations where radar detectors are illegal.

Notable Features of the Uniden R3 Radar Detector

1) Range and Sensitivity 

In terms of range, you cannot do better than the Uniden R3. This device is seen as the detector with the most impressive range by radar detector buffs. It picks up signals from miles away, giving you a lot of time to get your driving act together. 

It also has a 360-degree coverage that sends you alerts from radar detected in any direction. That is great because you can now “see” around corners, too.

Sensitivity is another attractive feature of the R3. No matter the band, it picks up the signal and sends you an alert. This feature makes it almost impossible to avoid getting false alerts, but with this device, you can mute all known false alerts.

2) OLED Display

Uniden makes products with really bright and colorful screens, but the R3 takes that to a whole other level.

With this product, you get more adjustable brightness settings as well as four display modes. They are Dark, Dimmer, Dim, and Bright. You can select any based on the time of the day or your visual preference. There is also the auto-dim option that automatically dims your screen when it’s dark. 

3) BSM Filtering

Blind spot monitoring (BSM) is one advancement in radar detection technology that every user should be able to access easily. This filtering system helps you cut down on all the false radar alerts that are so prevalent these days.

Most radar detectors do not have this great feature, but the R3 is one of the few that does, a huge plus in its favor. With its ability to receive the latest firmware updates, you obtain adequate protection from false alerts.

4) GPS Lockouts

One feature you are going to enjoy is the GPS lockout, and this is possible because of the GPS chip in the R3. This chip allows your device to remember where every false alert encountered is located, and this makes your BSM even more effective.

The GPS lockout feature mutes these remembered false alerts or even automatically ignores them. Also, this handy feature allows you to monitor your current speed. As well as mute all alerts under certain speeds.  

5) Driving Modes

Nothing says convenience like preset modes with all the adjustments necessary for any situation. With the driving modes of the R3, you get to enjoy sensitivity settings ready-made for any driving need. These modes are City, City2, and Highway.

The City2 mode disables the X-band for you and reduces sensitivity to K-band. While Highway mode enables maximum sensitivity to every radar band.

6) Immunity from Radar Detectors

A mouthful, we know, but if you live in Virginia or Washington DC, then you need this feature. In those states, radar detectors are illegal, so patrol vehicles have detectors for finding radar detectors. The R3 is masked and not detectable to those devices. For a cop to prove that you’ve got one they have to stand right in front of your vehicle with their detector. That’s useless as you’d have detected them coming already.
