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 wavelength of
800-1000nm.
Laser Tips
If you are the targeted vehicle, a laser gun can often
determine your speed within a few seconds after you receive
an alert. In this situation, there is generally no time to safely
adjust your speed. However, if you are traveling near or
behind the targeted vehicle and receive an alert, response
time should be sufficient. Any laser alert, regardless of
duration, requires immediate action.
Radar Facts
A radar gun operates by transmitting radio waves at certain
frequencies which reflect off objects and are picked up by
the radar gun’s receiving section. When a radar beam reflects
off a moving target, a measurable frequency shift occurs. The
radar unit converts this shift into miles per hour to determine
your vehicle’s speed.
Radar Facts - Continued
This laser/radar detector receives signals from traffic radar
guns at X Band (10.500 - 10.550 GHz), K Band (24.050 - 24.250
GHz), and Ka Band (33.400 - 36.000 GHz).
Note:
Your radar detector is designed to alarm if an officer
is transmitting on any one of the above radar bands.
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 police measure the time it takes
your vehicle to travel a known distance.
Radar Detector Detectors: VG-2, Spectre
The Interceptor VG-2 or simply VG-2, is one type of
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,
these devices are known as a “radar detector detector”
(RDD). An RDD is the primary tool used by the police to
identify radar detector equipped vehicles. If caught in a
state or country where detectors are illegal, drivers risk
losing their radar detector and receiving a fine. In addition,
instant-on radar is almost always used in combination with
an RDD, leaving unsuspecting motorists
