Since climbers began taking whippers, belayers have been catching big falls. When the belayer is lighter than the climber, they deal with the danger of being lifter off the ground or pulled into the rock. As Edelrid states, “The Ohm is an innovative, new solution for the problems experienced by climbing partners with a significant difference in weight. That is to say the risk for a heavier lead climber if their partner has difficulty controlling their falls and the risk for a lighter belayer if their partner’s falls pull them off the ground, hurling them against the wall.

“The Ohm is an assisted-braking resistor that you install at the first bolt in the safety chain. In the event of a fall, the OHM increases rope friction so that a lighter belayer can hold a heavier partner without being suddenly pulled off the ground and thrown against the wall. The OHM still enables smooth paying out and taking in rope when climbing and belaying and has no negative affect on handling. The OHM was developed for use at both climbing walls and outdoor sport climbing venues.” For more on this great new piece of gear see here.
