SPEED MONITORING TECHNOLOGIES

For best protection, keep these points in mind:
• Because your vehicle’s license plate or headlights are the laser gun’s
primary targets, mounting your 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 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 +/- 10mm.
• Pro Laser™ I II III
• LT1 20-20
• Ultra Lyte
Other Speed Detection Systems
Several techniques other than radar or laser are used to meas-
ure 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.
Radar Detector Detectors (VG-2)
The Interceptor VG-2, or simply VG-2, is a microwave receiver used
by police to detect signals radiated by the local oscillator of a radar
detector. Because its purpose is to identify persons driving with
radar detectors, the VG-2 is known as a “radar detector detector”.
The VG-2 is the primary tool used by the police to identify radar
detector equipped vehicles. If caught, in a state where detectors
are illegal, (see page 26), drivers risk losing their radar detector and
receiving a fine. In addition, instant-on radar is almost always used
in combination with a VG-2, leaving unsuspecting motorists vulner-
able to receiving two tickets — one potentially for speeding, the
other for possession of a detector.
Having a radar detector capable of detecting the VG-2 may alert
you to the presence of a speed trap.

It is the responsibility of the individual radar detector owner to
know and understand the laws in your area regarding the legality of
the use of radar detectors.
