Ohm II

Ohm II is a locking system for the Edelrid brand, fixed upstream on the first piton of the belay chain.

This is a system developed by Edelrid to prevent the belayer from being thrown high when the difference in weight with the climber is too great. Here is the second Ohm version with a few improvements to make it easier to use.

It therefore compensates for the difference in weight between the lighter belayer and the heavier climber. Ohm II is attached to the first quickdraw, allowing you to slow down gradually in the event of a fall, independently of the belay system. The risk of collision is therefore reduced.
