SPEED MONITORING
Laser Facts (Continued)
• 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 ± 50 nm including but not
limited to the following:
• Ultra Lyte
• LTI 20-20
• LTI TruSpeed® S
• Pro Laser™ I II III
• Laser Ally
• Laser Atlanta® Stealth Mode
Other 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:
• Pacing - A patrol car drives behind you and
matches your driving speed.
• Vascar/Aircraft - The time it takes a vehicle to
travel a known distance is measured.
