We have heard from several sources that it's not uncommon
for two beacon to be "stacked" on top of one another in a
guides exam. This scenario may be tricky to solve because you'll
receive two signals but the second signal will be difficult to
isolate. The scenario may look something like this: a reading of
1.2 meters and a reading of 1.8 meters. Be confident in the
information your beacon is providing. If you are sure that there
is not another signal in close proximity within 1 circle (from
the three-circle method technique) or one pass using micro-
search strips of 3m, you probably have some stacked signals.
Be aware! We get used to practicing for signals that are spread
out from one another on a horizontal plane. Practice searching
for multiple signals that are on a vertical plane, or stacked on
top of one another.
While no two scenarios are the same, the above provide you
with a solid framework to work through any complex scenario.
But, remember beacon searching is the easy part. Shoveling is
the ultimate crux in an avalanche rescue and the efficiency of
your rescue will greatly depend on how much power you have
to dedicate towards excavation. Be sure to check out BCA's
video on the "ABC's and D of digging."
Typical Guiding Exam
A. Stick to a disciplined signal
search, only leaving your pattern
once the received signal is less
than 20 meters. Mark the point at
which you depart from your signal
20m
search pattern.
B. Locate victim #1. If multiple burial
light is flashing use special mode to
X view additional distance readings
C. If it is tough to determine
direction of beacon #2, due to close
proximity, use micro-search strips
2 meters apart.

D. Once victim #2 is located,
use SP mode to determine
location of victim #3. If no
new signal is found in SP mode,
return to where you abandoned the
signal search and continue on,
ignoring signals #1 and #2.
