SPEED MONITORING TECHNOLOGIES

ARE DETECTORS LEGAL?

Check with your country's laws regarding radar detector
ownership and use.
It is the responsibility of the individual radar detector user to
know and understand the laws in your area regarding the legality
of the use of radar detectors.
POP™ Mode
POP™ Mode is a feature on some radar guns operating on K and
Ka bands. When the gun is in POP™ Mode and
activated, a brief burst of energy, less that 1/15 of a second, is
transmitted and the vehicle's speed is quickly acquired. A
detector without POP™ Mode detection capability cannot respond
to this brief transmission.

Laser Facts

It's well documented that many radar guns cannot reliably
provide the speed of a targeted vehicle that is traveling in a group
of vehicles. In contrast, a laser gun can target a specific vehicle out
of a line of traffic and determine its speed. The advantage of laser
over radar in terms of target identification is the result of the laser
gun's narrow beam. A radar gun's
transmission can cover more than a four-lane highway at a
distance of 1,000 feet, compared with a laser gun's transmission
which covers about 3 feet at the same distance.
