Notes

Slippage in the REVERSO 4 has the effect of limiting the forces at work. The difference between GRIGRI and REVERSO 4 can be significant: up to 30% less force on the anchor.

The climber experiences a softer catch with the REVERSO 4 in these configurations.

The impact on the belayer is reduced, the force is weaker due to rope slippage. However, control of the rope, and thus stopping the fall, remains dependent on the belayer being very alert.

Advice:

The belay device should be suited to the situation.

Slippage in the REVERSO 4 increases climber displacement: one must be especially vigilant where there is a risk of hitting the ground or a ledge. This slippage can make stopping a fall particularly difficult for the belayer: gloves must be used, especially with a new skinny rope.
