I see a lot of sketchy and unsafe belaying here. No different than back home really. I’m not sure why some people take such a casual approach to this because the belayer is literally holding the climbers life in their hands. BTW, I wanted to make sure I was using the word “literally” correctly. I think I am. In my search, I found this: http://theoatmeal.com/comics/literally It’s pretty damn funny.
The Petzl Gri Gri is one of the most popular belay devices here. It is common to see people misusing the device according to the manufacturers instructions and using belay techniques based on outdated practices. Please use the “hand down” method (brake hand thumb toward device) and NEVER TAKE YOUR BRAKE HAND OFF THE ROPE!
