Here is what you need, for a ski tour on the glaciers. If you hire me as a guide, I can provide you everything that is in red in the list. I you need some of those things, please let me know in advance.
When the words are blue you can use the link in order to understand better, what I'm speaking about.
Beacon (Transceiver)+ extra battery (If you use my transceiver 3 battery AAA should work, anyway we will double check before to start)
