Belayer requires significantly less hand braking force to arrest a fall Lowering a heavier climber is much easier to control OHM is attached at the first bolt in the safety chain
When there is a significant weight difference between belayer and lead climber, the assisted-braking resistor increases rope friction. If a fall occurs, the OHM boosts rope friction to help a lighter belayer hold a heavier lead climber easily.
Minimum weight belayer: 40 kg For single ropes from 8.9 - 11 mm
CE marking: CE 0123, Weight 470 g
Should a lead climber fall at the first bolt, the OHM significantly reduces the risk of a possible ground fall Rope handling when belaying a lead climber not affected (no additional friction when paying out rope) Recommended weight difference (lead climber > belayer): 10 - 40 kg
