The 'Belay-tionship' with your climbing partner is something that is built up over a number of years. After all those hours spent down the wall and on the crag you've finally built up enough trust to let them hold your rope in virtually any climbing situation. What if however there is a substantial weight difference between you and your partner? That's where the EDELRID OHM comes in.

The Ohm was named after George Ohm and is the unit used to measure electrical resistance. The EDELRID OHM adds resistance into the belay system, ensuring the belayer gets a softer catch and the climber a softer fall. You can see where we got the name from now...

Now EDELRID are giving you the chance to save your 'Belay-tionship' by giving away an OHM to one lucky climbing duo. All you need to do to be in with a chance of winning is have a read about the OHM and answer the simple question.

OHM (RRP: £110)

The OHM is an assisted braking resistor, designed to add friction into the belay system when there is a large weight difference between the belayer and climber. In the event of a leader fall the OHM slightly cams the rope, adding a small amount of friction into the belay system. This allows the lighter belay to easily hold a heavier leader fall.

Key features:

• The OHM has no moving parts, it works solely on rope angle. This ensures smooth operation and a long lifespan
• Lowering a heavier climber is much easier to control
• The OHM attaches to the first bolt, replacing the quickdraw
• If the leader falls at the first bolt, the OHM significantly reduces the risk of ground fall
• Rope handling when belaying is not affected, paying out rope is just as easy as if the OHM wasn't present
• The reccomended weight difference between the climber and belayer is 10 - 40 kg
• Minimum belayer weight is 40 kg
• Suitable for use with 8.9 - 11.0 mm ropes
