For those who are starting leading, such as those on our Alpine Autonomy courses, an auto locking belay device is a great piece of kit. It allows a lead climber to belay up to two climbers on separate ropes. Our technical store in Windermere stocks the Cassin Piu, which is engineered to provide solid lock-offs when belaying and smooth abseils. The thick walls also help prevent over-heating and ensure greater durability. For ropes 8-11mm. The retail price is £16.99, though see the discounts page for offers.
