The Whistler CR85 - It Just Makes Sense

It's the age old question... Do I keep getting speeding tickets, or do I not keep getting speeding tickets? It can be kind of hard to decide sometimes. There are only a handful of ways to better spend your money than on a speeding ticket. I don't know, like a new video game, a fancy dinner, new shoes, go see a movie, a down payment on a new car... Yeah, but only a few things that are better than a speeding ticket. 9 out of 10 of the people here at Sonic Electronix agree, after heavy debate, that speeding tickets aren't a good thing. As for that 1 person who disagreed, they weren't even there for the vote. But you know, it's up to you to decide really. The average cost of a speeding ticket is $200 plus the increase on your insurance... Or you know, there's always this CR85 radar detector that can help prevent all of that. It really is a tough choice; speeding tickets... Or nice things... But we'll let you decide, we know you'll make the right choice.

CR85 360 Degree Radar Protection

This feature means that the unit displays that strength of the received signal.
Brightness Control
If the brightness of the unit can be conveniently adjusted and controlled, it will be listed here.
Turn-on/off Select Bands
Many radar detectors can detect many different bands of signal. This feature designates if the user can select what bands he or she has on or off.
Unit Mounting
Different radar detector are attached to the vehicle in different ways. The most common is for it to be suction-cupped to the windshield. This allows the unit to be moved from one vehicle to another with ease. Another mounting option is called remote-mounting. A remote mount unit is directly installed into your vehicle.

Other ways to mount your radar detector include Velcro and adhesive.

Suction cups
Power Source
The power source is the method in which the unit receives power. Some units will be powered by batteries, while others will need to be plugged in to an AC or DC power source.
12V DC Car Adapter
Direct Power Accessory
If there is an optional accessory to the unit that will provide power, it will be listed here.
Travel Case Included

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.
X Band
X Band is a frequency used for detecting speed from a police radar.
K Band
K Band is the most popular radar frequency band that is used today. It is able to detect speeds from a stand still location, or from a moving vehicle
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.
This feature specifies if the unit will detect lasers.
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.

Good value as a city driving companion

December 12, 2013

This detector has frequency display and selectable bands. It's price makes it a good value considering those features above. I use this as my everyday city radar/laser detector. Would recommend a escort redline or V1 for extreme highway driving tho.
