if you really wanted to be "safe" according to petzl Wink
This does not help your argument at all.

of course if the new RC stance is that the gri gri is now suddenly a hands free device ... now thats something ...
You are confusing belaying hands free with having a loaded locked off gri-gri hands free. They are NOT the same!


A loaded grigri is 100% safe to go hands free provided the cam isn't forced open.


Forcing a cam open takes a fair bit of force that is very unlikely to occur when loaded. Like many such situations if you want to make it super safe tying off helps.

ummmm ... that petzl diagram was very specific for descending (rappelling) on a gri gri ...

so you are saying that its 100% safe for one to go "hands free" on a gri gri if the cam is engaged ...

so for example is my climber is resting on the rope, the cam is fully engaged, i can let go of the brake hand ?????????

of course if you are swinging around theres absolutely no chance anything will happen at all will there now Wink

im gonna go ask petzl about it ... i suspect theyll know if its "100% safe"
