Escort Radar Detector - 8500 x50

The Escort Radar Detector 8500 x50 claims to be “the most advanced and sophisticated detector ever!”

The 8500 can detect all radar bands currently used in North America for speed detection These include X, K and Ka bands. The unit als features detection diodes for detecting lasers. The Escort Radar Detector also has a ZR3 laser jamming system which gives powerful protection from laser detection. It also has the technology to dectect pop radar.

When a radar is detected an audio alerts warns you with a beep.

Ever wondered how do speed cameras work ?

There are various types of speed cameras. Most use radar, or loops which and buried in the road. Once they detect you are going over a certain speed they flash and then flash again. This is to measure how far you have moved between flashes. This then allows the speed camera to work out your speed.

Another common type snaps the motorist using a “radar gun” These are either hand-held or set up inside police vehicles. These send out radio waves that bounce of a vehicle. From the waves bouncing back to the radar detector the distance and speed can be calculated.

The minimum trigger speed is the speed limit plus 10% plus 2mph according to the London centre for transport studies.
