An avalanche transceiver emits a pulse which can be tracked by another device in search mode. With modern triple-antenna/digital devices we can very easily search and locate a casualty. Probes are long, thin poles which can be pushed into the snow to assess how deep and in what position the casualty is buried.
What must you remember in the event of an avalanche?
When winter mountaineering in places like scotland, what must walkers and backpackers remember?
Scotland is a unique environment, because the weather and snow pack changes at a phenomenal rate.
Lots of spare clothing that can cope wet and windy weather is important. Don’t forget gloves; you will require at least three pairs (and perhaps a fourth for emergencies). I never leave home without a pair of good quality goggles with a low light lens.
A well packed rucksack is also critical – try to envisage in what order you will need your items, so that you don’t have to repack on the top of a mountain while the wind loads your backpack with spindrift!
