Helping climbers with larger weight differences to climb together indoors and out, the Edelrid Ohm assisted braking device increases rope friction so a lighter belayer can hold a heavier lead climber.
Features
Ohm attaches at the first bolt in the safety chain; in the event of a fall, the rope is pulled into the device's braking unit and the fall is progressively arrested
With Ohm, belay normally with your preferred belay device; Ohm is not a replacement for a belay device
The Ohm makes it easier for a belayer to hold a fall and limits how high he or she is pulled off the ground; this can help reduce the distance a lead climber falls
Lowering a heavier climber is also easier to control
Ohm does not increase friction for the lead climber, nor does it negatively affect paying out the rope
