Laser Facts - Whistler XTR-475 Owner's Manual

SPEED MONITORING
POpTM Mode
POP™
Mode is a feature on some newer 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:
M
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. For best protection, keep these
points in mind:
• Because the vehicle's license plate or
headlights are the laser gun's primary targets,
mounting the Whistler detector on the
dashboard can improve laser detection at short
range.
• Do not follow closely behind any vehicle. If you
can't see past a vehicle ahead of you, chances
are your detector won't either.
• The receiving range of your laser detector will
not be the same as a radar detector. Laser guns
are most often used at short range.
Whistler Laser-Radar detectors receive all current
laser guns which operate at a laser wavelength of 905
+/-10nm.
