Features
Transceiver Checker – SAH confirms that a transceiver is switched on and working using a sound and visual display. By holding down both function keys within 10cm of a transceiver, self and group checks can take place in close proximity without the need to spread team members’ meters apart. Transceivers both transmit and receive a signal, so ensuring your transceiver is working is one of the most important safety features as they are the quickest way to be found or to search for a buried skier, boarder or climber after an avalanche.
Slope Angle – Using an in-built inclinometer SAH gives you a quick and accurate reading of the slope angle. Place the device either directly onto the slope or onto a ski pole (or similar) with the screen facing upwards. Notoriously hard to calculate, slope angle is essential to know when it comes to avalanche risk assessment. Research has shown that 70% of avalanches occur on slopes greater than 30° and up to 50°.
Thermometer – SAH quickly measures ambient air in Centigrade and Fahrenheit when you scroll through the display. Temperature, like slope angle is difficult to accurately guess. A rapid change in temperature is a big warning sign. A rise of more than 8°c in 12hrs significantly increases the risk of an avalanche. When the temperature drops beneath -25°c weak layers frequently develop. Snowpack stability and avalanche risk are hugely influenced by changes in temperature caused by warm air, cold air, rain, snow and sunshine.
Altimeter – SAH identifies your altitude in metres when you scroll through the display. Weather forecasts give information on snowpack conditions at specific heights. Knowing your altitude will allow you to quickly match this information. The altimeter feature will also help to determine your location, assist with route planning, enable you to calculate height gained and lost during ascents and descents which all aids decision making and assessment of avalanche risk when combined with SAH’s other functions.
24hr Clock – SAH shows the time in 24hr mode when you scroll through the display allowing you to see the time without having to remove gloves or find your watch/mobile phone under layers of clothing. Time awareness in terms of backcountry planning and safety is critical and is an additional factor/consideration when it comes to decision-making.
Power Monitor – SAH shows the devices remaining battery capacity when you scroll through the display. As an added safety feature the battery icon will start to flash once the capacity drops below 20%. The Lithium battery is charged with a USB to Micro USB charging cable (supplied).
Elastic strap and ski pole clip included.
