3 – Uniden DFR1 Long Range Laser/Radar Detector

Overview

The Uniden DFR1 is one reliable radar detector that fulfills most needs of every driver in the highway, even with its value and it being at the lower end of the market. Many were blown away by its accurate, wide-ranging, and seemingly false-free device, especially when it costs below a hundred bucks.

The Uniden DFR1 manages well with signal detections, especially with common signals from radar guns.

It alerts the user right away through its audio alerts and then determines what band range the signal is coming from.

PROS:
  • Long Range Detection Capability
  • Can protect from X, back, and Ka-band alarms
  • Crisp and clear pop and laser alert alarms
  • Options to drive with Highway/City/City 1 modes

CONS:
  • Alert sound is high pitched, which may be disturbing for a few.

The Uniden DFR1 performs almost as well as its other much expensive brothers, the DFR6 & DFR7, only it lacks traffic sensor filters. It displays the type of frequency it detects on its display, whether it’s x, K, KA, or L.

It also indicated the signal strength (1-5) so the driver knows approximately how near or far the source of the signal is. This way, cautionary actions can be calculated even more, with even more assurance of no speeding violation.

With Whistler first-class quick signals detection you will have the most powerful detector among others which will last you for years. If you want a radar detector which is more capable than many other supreme radar detectors under $100, there aren’t many choices which are more viable than this model from Whistler.

The blue LED display ensures that you will never have issues seeing the screen of your radar detector, even in the harshest of glare.

Whistler CR75 is an excellent choice for the countryside as it features superior range when compared to other models in its category and price range.

The Whistler offers you the ability to detect quick signals that ensure that this model will not be outdated for years to come unless radar detection bands change.

The adjustable volume for this detector means that you will not have to deal with any of the issues that you get with most other radar detectors that can tend to get annoying in the car. The whole user interface of this radar detector is simply a joy to use, unlike other models.

5 – Whistler XTR-135 Radar Detector

Overview

Cheap, small, yet provides superb coverage – the Whistler XTR-135 is an excellent radar detector with a price tag under $100. For those with a higher budget, topnotch radar detectors priced at $300 are great options, too.

Design-wise, we love how compact this radar detector is because stealth mode is so easy if you don’t want anyone getting curious as to why you have a radar detector in your car. But don’t let the small size fool you; this radar detector packs in enough power to give you reliable performance on the road.

This pocket-sized device provides total band protection from all laser and radar signals. You also get full coverage on all sides of your car, thanks to its 360-degree protection.

Guaranteed, this radar detector will pick up those hard-to-detect signals whether it’s coming from the front, rear, or sides. 

As an added feature, you’ll also know the strength of the signal so you can react accordingly and reduce your speed. 

Like most radar detectors, the Whistler XTR-135 has a City Mode and Highway mode. When you’re driving on the highway, sensitivity is increased so you’re alerted immediately if there are radar or laser guns targeting the area.

On the other hand, City Mode lowers the sensitivity level when you’re driving in the city since there are a lot of false threats waiting to make your radar detector go crazy.

PROS:
  • Very compact size, good for stealth applications
  • 360-degree protection
  • Highway and City modes
  • Total band protection from radar and laser
  • Volume control

CON:
  • Smaller display than other detectors.

This radar detector also conveniently comes with a volume control option. Honestly, we don’t know why many radar detectors to this day still don’t incorporate this simple function. Controlling the volume is handy if you don’t want to be bombarded by loud alerts while you’re on the road. If you want a quiet drive, you can mute your radar detector as well. 

A reason to complain is the smaller icon display. It does take a while to get used to, but the small display is pretty much expected given the size of this radar detector. 

All in all, we like how this small radar detector is able to deliver such a performance that even bigger radar detectors fall short at. Although the small display is a bit unsettling at first, the Whistler XTR-135 provides great functionality to help you avoid speeding tickets.

6 – Cobra SPX 955 IVT Radar Laser Detector

Overview

Want the best value for your money? The Cobra SPX 955 is tough to beat in the under-$100 department. Design-wise, it’s more compact than other units in the SPX line. But more than appearances, the Cobra SPX 955 delivers reliable performance too.

There’s two ways to get alerts on this radar and laser detector: through the display or through audible alerts. I love the UltraBright Data Display on the SPX 955; it’s easy to read whether day or night.

Plus, you can adjust the brightness from “bright” to “dim” to “dark.  If you’re going stealth mode especially during night driving, switching to dark is useful.

You can set up the Cobra SPX 955 to emit voice or tonal alerts. Such unique tones and readouts help you know what’s going on even without glancing off the road – a safety feature as well.

The Cobra SPX 955 detects both radar and laser for ultimate protection against speeding tickets. It detects X, K, Ka, and even the less common Ku bands. It’s also instant-on ready so you won’t be caught off guard by hard-to-detect POP guns.

When you’re on the road, a fast response from your radar detector is crucial for you to have ample time to reduce speed.

PROS:
  • Adjustable brightness
  • Voice and tone alerts
  • Ultra-fast response
  • IVT filter system
  • IntelliMute and IntelliMute Pro

CON:
  • Device may get warm after a long time of use.

Armed with Xtreme Range Superheterodyne Technology (it’s a mouthful, I know), you get lightning-fast detection and extra range so you’re warned as early as possible. Plus, you’re protected against VG-2, Spectre I and Spectre IV+ RDDS for undetectability.

To handle annoying false alarms, the Cobra SPX 955 has several features in place. It has an IVT filter system which reduces false threats coming from sources such as collision avoidance and cruise control systems.

The other features are IntelliMute and IntelliMute Pro. The former is a mute function that lessens false alerts depending on your set engine RPMs, while the latter prevents detection by RDDs when you’re traveling at slower speeds.

Overall, the Cobra SPX 955 has a great feature set even at under $100. If you want a radar detector that’s affordable yet equipped with advanced features, this will not let you down.
