Avalanche Beacons
Avalanche beacons are probably the most essential piece
of equipment for anyone who plans on exploring the backcountry during
the winter. The inherent risks involved with this sort of outdoor activity
makes a location device necessary in the event of an emergency. Many
people over the years have owed their lives to these devices.
Avalanche beacons are manufactured in a few basic configurations. The
number of antennas on a beacon can be an important factor to consider
when purchasing. The most basic is the single antenna variation, which
can have quite a long range assuming the receiving and transmitting
beacons are lined up. However, when out of alignment, the range is significantly
shortened.
Two and Three antenna avalanche beacons are generally the preferred
devices of professionals. These devices use the multiple antennas to
more accurately locate the buried signal. These beacons also offer the
added security of a directional indicator, allowing for a faster rescue
of the victim.
