Période

1970's

Canada

Taken from acquisition proposal, Reference 1: This device represents the early use of avalanche beacons in Canada. Served in a number of avalanche rescues, this was used by the Parks Canada staff in the mountain rescue program.

Fonction

An avalanche rescue beacon (radio transceiver), is a radio transmitter-receiver device used to detect people buried in snow. This analog device broadcasts a pulsed signal as an audible tone which is picked up by users with other beacons and heard wearing the supplied earphone.

Technique

Taken from acquisition proposal, Reference 1: This second generation SKADI also operates at the frequency of 2.275 kHz and uses an earphone. As above, the invention of the first practical avalanche beacon is owed to a research team led by Dr. John Lawton at Cornell Aeronautical Laboratory in Buffalo, New York who, influenced by avalanche expert Ed Lachappelle in 1968 developed the Skadi. This analog device broadcasts a pulsed signal as an audible tone and picked up by other beacons. As a second generation model, it likely went into production about 1972-74. In Europe, the first avalanche rescue beacon was commissioned by the Swiss Army in 1968 and developed by the Autophon company. Using the newly introduced European standard frequency of 457 kHz, development of the Barryvox VS68 took almost 2 years and soon thereafter found civilian use. The standard of 457kHz was adopted in 1986 by the International Commission on Alpine Rescue (IKAR), in 1996 by the American Society for Testing and Materials (ASTM), and also by the American National Standards Institute (ANSI).
