At the risk of starting a "mine is better than yours" debate I own a Valentine One. Unsurpassed laser range, huge range on all other bands. It has
saved me on laser already as well as Ka. It's expensive at $399, but what is a ticket and the commensurate raise of your insurance worth? If you think you drive fast enough where speeding might cost you money, get the best you possibly can afford. The top three detectors as far as range and sensitivity are: Valentine 1, Escort 8500 X50, and the Bel RX-65. Bel and Escort are the same company, the two detectors mentioned are virtually the same internally but each have unique features. I have tried all three (they all have 30-day return guarantees-more than enough for evaluation purposes), and chose the Valentine One.
I didn't see a Province/State Listed for you so here's a few things you might consider as well:
-what type of radar is used in my driving area? (X, K, Ka, Laser)
-is any of it instant on or is it all constant on?
-are radar detectors legal in my Province/State? Where RDs are illegal, quite often RDD (radar detector detectors) are employed.
There are other things to consider as well, so go to this website- radardetector.net . They have the most comprehensive knowledge base that is generally accurate. You will find fans and detractors of all brands. So go to this particular link first http://www.radardetector.net/NEW-USE...ing-15422t.php
it will answer the basic questions first and is very informative. If you are considering a Cobra, read that forum especially to see what most people think of them. Oh, and don't get the ones that run on batteries, they don't constantly scan for radar in order to conserve battery power.
As stated in above posts, your eyes help as well, remember that a detector is a driving aid
. And they CAN alert you before the last second if you have chosen correctly. I drive approximately 100,000 km a year, and it has definitely been worth every penny. Matter of fact, it would be worth it at twice the price, but that's just my opinion.
