Edelrid OHM

The Edelrid OHM is an innovative, new solution for the problems experience by climbing partners with a significant difference in weight. What that means is the risk for a heavier climber if their lighter partner has difficulty controlling their falls, and the risk for a lighter belayer if they are pulled off the ground and hurled against the wall. This problem is particularly inherent within climbing couples, where men tend to be significantly heavier than women. You can, of course, use a weight bag to balance the weight difference, but they are highly impractical to take everywhere with you and restrict freedom of movement. Autoblocking belay devices also assist with braking, but without a weight bag, the belayer still faces a sudden pull and the leader a heavy fall.

The Edelrid OHM is an assisted-braking resistor that increases rope friction, allowing the lighter belayer to safely catch falls. The climber attaches the OHM to their harness with the rope run through it, and, when they reach the first bolt, they simply clip the OHM to the anchor like they normally would a quickdraw. In the event of a fall, the rope is pulled into the device's braking mechanism, which reduces the braking force needed to be applied by the belayer and prevents them from being suddenly pulled off the ground, decreases the fall height of the leader, and allows for safe, dynamic arresting.

The OHM is not designed to affect rope handling. It enables smooth paying out and taking in rope when climbing and belaying and has no negative affect on handling when used both in indoor gyms and for outdoor sport climbing.

The OHM benefits both climber and belayer. The belayer can feel safe knowing they won't be hurt and have much more control of their partner's fall, and the lead climber can climb to their limits knowing they will not face a severely harsh fall every time they climb. Compact and light, the Edelrid OHM has been designed to be easy to carry and easy to use both indoor and out, so belayer and climber can perform to their full abilities without restrictions.

Features

OHM

Full Features List

• Fall and pull heights are greatly reduced, allowing climbers of different weights to climb as if there were no difference
• Belayer requires significantly less hand braking force to arrest a fall
• Lowering a heavier climber is much easier to control
• Clips onto the harness with the rope fed through, then is attached to the first bolt in the safety chain, exactly as a quickdraw is
• Rope handling when belaying a lead climber not affected (no additional friction when giving slack)
• Recommended weight difference (lead climber > belayer) 10 - 40 kg

OHMy good

well, it allows me to climb with my 12 years old son :-) My weight is 75 kg while his about 40 and everything works fine. Sometimes OHM seems to be oversensitive (extremely overhanging walls, really high first clip) and you have to shake the rope to release it.
