Ohm II Oasis-Night

The Ohm II Oasis-Night is a belay device manufactured by Edelrid, which is attached upstream to the first carabiner in the Safety chain.

This is a system developed by Edelrid to prevent the belayer from being thrown into the air when the weight difference between them and the climber is too great. Here is the second version of the Ohm, featuring a few improvements to make it easier to use.

It therefore helps to compensate for the difference in weight between the lighter Belayer and the heavier Climber. It Ohm II attaches to the first Quickdraw, allowing the climber to slow down gradually in the event of a fall, independently of the belay device. The risk of collision is therefore reduced.
