Direct Power Accessory
If there is an optional accessory to the unit that will provide power, it will be listed here.


Number of Detected Bands
This number indicates the number of bands the radar/laser detector protects against. The term band includes different radars, lasers, and safety signals, among others. The higher the number, the greater the protection.
Ka Band
Ka Band operates within the frequencies 26.5-40 GHz. This is the newest introduced radar band and it is becoming more and more popular. It rarely has a false alert.
Pop Alert
Some radar guns operate in a POP mode so they can get a speed reading of a target vehicle extremely fast, resulting in most radar detectors not being able to consistently signal an alert. There are very few radar guns in service in the U.S. capable of POP mode operation. If your radar detector is Pop Alert capable, you may notice an increase in Ka-band false alerts when POP mode radar detection is switched on.

March 30, 2014 - My Review of the Whistler CR90 radar

March 30, 2014

Whistler CR90 radar The Whistler CR90 Portable Radar Detector is in my budget for realistic affordability. I received my detector March 21, 2014, and it works as well as any radar in its price range. I am not a speed-demon but on-the-side-of-caution, I am grateful when I do need it. There are many price-ranges that do determine a radar’s performance. Simply stated, “The more advance technology a company puts into its product will cost more”. With that said, I choose to use my budget as a ruler to determine the best radar for me. I have read forums by customers and professional critics about radar detection quality. Given all the environmental conditions and variables driving conditions, the consensus is “If the radar detects too late - - than it did not do its job (talking about detectors under $200)”. For those with a need-for-speed then the best up-to-date technologically advanced radar is worth the price. For me, The Whistler CR90 meets my needs for city and interstate driving (even with false alarms, etc., it is in my price-range). This radar is up-dateable via USB with a PC; but not for Mac users like myself. For what-reasons, the majority of radar detectors are non-compatible with Mac for updates. My get-around is to use someones PC to periodically update my detector. Last but-not-least suction cups to hold my detector onto the windshield; my preference is no suction-cups. Look-around for bargains, clearance. Companies will throw-a-bone and include a mount to securely attach to your rear-view mirror. Two things: 1) make sure the mount WILL PROPERLY FIT the rear-view mirrors cylindrical shape stem (research, call the company, etc.); 2) if mount not included, buy it separately. In conclusion, I consider this Whistler CR90 a value-buy worth looking into (also I got the Rogue Radar Mount R2011-103-WHIST-CYL-RM). Both the radar and the mount are well made products, and because they both serve the designed purpose, I give a five star for its practical application and cost.
