What is the Ohm?

The Ohm is named after Georg Ohm and is the unit used to measure electrical resistance. The Edelrid Ohm does just that, it adds resistance into the belay system. You can see where Edelrid got the name from now.

What does the Ohm do?

, 56 kb
Most people will have experienced the situation where there is a significant weight difference between you and your climbing partner, classically the lighter belayer had to put up with being dragged up to the first bolt every time the heavier climber took a fall. Not anymore, the Ohm adds resistance into the belay system by replacing the first quickdraw, it works with a large range of single rope diameters (8.9-11mm) making it an extremely versatile device.

Due to the Ohm's intelligent design it only engages when the climber falls, so paying out slack and clipping is still as easy as it ever was.

Not only that, the Ohm also makes it easier for the lighter belayer to lower the climber, by adding just the right amount of friction into the system whilst still giving the belayer the same control as if the Ohm wasn't present.

Watch this short video to see the Ohm in action.

Ive used one of these for 5 months now, climbing walls & Spain, the weight difference between us is massive and it is brilliant. This mainly being used with a traditional friction device rather than gri gri. the...
most jamming problems can be circumvented by giving 1 meter more slack. The device is built with that in mind: without the extra slack there is no possibility for the Ohm to brake before the belayer is pulled of the...
We've had the Ohm for a few months and are still getting used to it.  The following is from a belayer's perspective - I've never tried leading with one myself as my climbing partners tend to be heavier than me. I'm a...
My climbing partner bought one of these as she is somewhat lighter than I am. It does what it says but there are a couple of caveats: it's much harder to give a dynamic belay when you fall off (in fact we haven't...
