14.3.1 Pinpoint Location
and Flux Lines
Depending on the burial depth of the victim
the pinpoint search begins earlier or later,
but normally around level A3 and below.
During this phase
hold the beacon verti-
cally above the snow surface!
After determination of the first maximum,
use an avalanche probe to pinpoint the
victim.
If the victim is buried at a great depth, use
a
pinpoint method
such as
“pinpoint
in a circle”
or
“pinpoint over a cross”
.

Detailed information about pinpoint search
methods can be found in the specialized
literature.
The three-dimensional shape of the mag-
netic flux lines around the buried beacon
does not permit an absolutely precise
location. You must use an avalanche probe
or a pinpoint search method to quickly
locate and rescue a victim!
Bracketing Method in the
Analog Search Mode:
Rules
●
Maximize tone
Search for the strongest signal
on a straight line.
●
Reduce tone
Reduce the volume until it can just
about be clearly heard.
●
Search at right angles
Turn through 90° from the first search
direction.
Remember
●
Hold the beacon vertically
●
Move swiftly
The volume will only change
when you move.
●
Search quietly
With low volume the differences
in volume can be clearly heard.
