Slope Angel Halo
Transceiver Checker – SAH confirms that a a a a transceiver is switched on and and working using a a a a a sound and and visual display By holding down both function keys within 10cm of a a a transceiver self and group checks can take place in close proximity without the need to spread team members’ metres apart Transceivers both transmit and receive a a a a signal so ensuring your transceiver is is working is is one of the the the most important safety features as they are the the the quickest way to to be be found or or or to to search for a a a a buried skier boarder or or or climber after an an avalanche Slope Angle – Using an in-built inclinometer SAH gives you a a quick and accurate reading of the the the slope angle Place the the the device either directly onto onto the the slope or or onto onto a a ski pole (or similar) with the the screen facing upwards Notoriously hard to to calculate slope angle is essential to to know when it comes to to avalanche risk assessment Research has shown that 70% of avalanches occur on slopes greater than 30° and up to 50° 44
