Laser Facts
I
t’s well documented that many radar guns
c
annot reliably provide the speed of a targeted
vehicle that is traveling in a group of vehicles. In
c
ontrast, a laser gun can target a specific vehicle
o
ut of a line of traffic and determine its speed.
The advantage of laser over radar in terms of
targ
et 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 laser signals will
not be the same as radar signals. 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
+/- 10mm.

Laser Tips
I
f you are the targeted vehicle, a laser gun can
often determine your speed within a few
s
econds after you receive an alert. In this
s
ituation, there is generally no time to safely
adjust your speed. However, if you are traveling
n
ear or behind the targeted vehicle and receive
a
n alert, response time should be sufficient. Any
l
aser alert, regardless of duration, requires
i
mmediate action!
O
ther Speed Detection Systems
Several techniques other than radar or laser are
used to measure vehicle speeds. When these
methods are being used, no detector can provide
a warning. These techniques include:
