Clear communication is essential for a successful day on the mountain. On the one hand, so that everyone is on the same page and understands each other. On the other hand, the safety aspect of communication is also very important. Many accidents, unpleasant situations and frustration factors can be defused or completely eliminated through clever communication. But what to do if the communication partner is out of earshot? Radios can be very helpful here. But often you can do without extra equipment - or you don't have it with you when you need it anyway.
This is because the most instinctive form of communication is usually used spontaneously: wildly waving your arms around. And sticks. This often works quite well and, above all, quickly and easily. But the danger is that the other person doesn't understand what you mean because you don't speak the same language. Wild waving around can mean many things: from "Hey, take a great photo of me!" to "Watch out, a snow slab has just come loose above you!". And when it comes to the importance of the message, there is somehow a world of difference.
