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 you cannot
see through. If you can't see past a vehicle ahead
of you, chances are your detector can'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 wave length of 905nm
+/- 50nm including but not limited to the following:
• Ultra Lyte
• LTI 20-20
• LTI TruSpeed® S
• Laser Ally
• Pro Laser™ I II III
• Laser Atlanta® Stealth Mode
