Notable Features of the Whistler CR90 Radar Detector

1) Laser Detection 

The Whistler CR90 is well-built to identify Laser Atlanta Stealth Mode, Laser Ally, POP Mode, and other types of laser used by cops. The Whistler CR90 can protect you in every direction from radar detector and laser speeding devices. In term of sensitivity, this device tends to be more effective than other models in the market.

2) Effective Alert System

With the Whistler CR90, there is never a false alert generated. The beeping sound is clear and also the voice alerts to ensure that you maintain focus as you drive. The radar detector also notifies you when you over-speed and once a threat detected, giving you more than enough time to adjust yourself.

3) Traffic Flow Signal Rejection

One area where many people find the performance of radar detectors to be unsatisfactory is the issue of false alarm filtering. This issue is most vulnerable to radars that are released from new cars which does not assure a drive without any false alert.

However, there has been an attempt to reduce that with TSFR, which allows the radar detector to ignore the signals that come from planted traffic equipment.

4) Audio Alarm

The Whistler CR90 has an Audio Alarm feature that will notify you to slow down before you reach the Speeding Checkpoint. The Audio Alarm is also supported with a Visual Alarm that means you will be notified by two alarms simultaneously before you arrive at the nearest Radar source.

5) Regular Updates

The Whistler CR90 Electronics is constructed to provide regular updates. This update includes the software update for Radar Detection sensors, GPS data, and Audio Alarms.

6) GPS

The radar detector comes with an inbuilt GPS. When you merge the GPS technology with the radar detectors, their union is something great.

The Whistler CR90 has the GPS, which keep tabs on the detected speeding checkpoints on the map as well as other drivers, who are making use of the same radar detectors. This inbuilt GPS also helps the device to filter the false alert warnings that may arise due to conflicting signals. The use of GPS makes the detection prowess of the Whistler CR90.

7) Long Range

The Whistler CR90 Radar is capable of detecting laser and radar sources from far distances. We found out that the CR90 detector has a success rate of over 90%, which is way better than any radar detector device. The Whistler CR90 can detect different kind primary Radar such as the Ka, K, and X that are used by the Police Department.

8) Stay Alert

The best thing we found about the Whistler CR90 is the Stay Alert Feature. When you enable this feature, it beeps every minute, prompting the driver to press a button as an indication that he/she is active.

In a situation you doze off and miss clicking the button, the radar detector will let out a loud sound that can wake you up. This feature comes in handy during long distance, night drives.
