Slowly rotate the Tracker horizontally in
your hand, but move rapidly during the
signal search. Do not abandon your search
path until you have captured a strong,
steady signal. Ignore irregular signals,
which can sometimes be caused by
electrical interference.
Coarse Search: The coarse search is the portion of the search from where
you have detected a steady signal to where you are close to the victim.
Once the signal is consistently detected, rotate the Tracker slowly on a
horizontal plane until the center direction light
The Tracker is now pointed in the direction of the strongest signal. The four
lights on either side of center tell you which way to rotate the Tracker to
engage the center light. The distance indicator
meters, how far you must travel (1 meter = 1.1 yards or 3.3 feet). If the
number on the distance indicator is increasing, you are on the same axis
as the victim's signal, but moving in the opposite direction. Turn 180
degrees, engage the center search light again, and continue your search in
the direction the Tracker is pointing. If you are stationary, but the distance
is significantly changing, you are probably detecting the signal of another
rescuer. Make sure all rescuers are in search mode before continuing.
You may find that, while following the directional lights, your route
follows an arc. This is because the Tracker follows the shape of the
electromagnetic signal coming from the transmitting transceiver's antenna.
The distance displayed is the distance to be traveled along that signal, not
the straight-line distance from you to the victim.
