Every once in a while a product comes along that revolutionises a certain aspect of everyone's favourite sport. The Edelrid Ohm is one of these. Edelrid are now giving two lucky climbers the chance to win one of these amazing devices. But before you enter have a read and see why the Ohm has become so successful.
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?
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.
