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

360° Total Band Protection

  • On the contrary to marketing gimmicks by competitors, only the following bands are used for radar enforcement:
    • X-band (rarely, more commonly seen in rural areas)
    • K-band (also used by traffic signals)
    • SuperWide Ka-band (most commonly used by police)
    • Laser
      • Detects Laser Atlanta Stealth® mode, Laser Ally® and the new LTI Truspeed® S
  • Don't fall for gimmicks claiming they cover 9 or 12, or more bands
  • POP™ Mode Detection allows the CR85 to respond to brief bursts of radar
  • High Gain Lens provides an increased field of view and longer range of detection
  • Safety Warning System™ keeps you informed of highway safety where transmitters are located

CR85 Technology Prevents False Alerts

    • Most commonly used band by police

  • 3 City Modes/Highway Modes

Good value as a city driving companion

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.
