I'm pretty sure I use a Gri Gri the right way, In fact I was complemented by the gym staff, " Finally some one who has read the instructions", but I know I have caught myself threading one the wrong way. Fortunatly I noticed, before the climber fell. That was out doors with out all of the distractions one gets in the gym.
I would prefer someone I had not observed belaying with a GriGri to belay on a normal belay device, there is a lot less room for error. |
