Ohm 2023
Description
Assisted-braking resistor for increasing rope friction when there is a large weight difference between the belayer and lead climber. In the event of a fall, the OHM increases the amount of rope friction so that a lighter belayer can hold a heavier lead climber without difficulty.
- 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
- 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
- Minimum belayer weight: 40 kg
- For single ropes from 8.9–11.0 mm

When I first tried the OHM in the climbing gym I was totally impressed with it. I experienced such a big difference between the use of the OHM and without it. For me as a small belayer it was quite convenient to belay and hold a fall. In a climbing gym I prefer the OHM when there is a big weight difference between the climbers.
