Assisted Locking Belay Devices are a recent innovation for single rope belay. Assisted locking belay devices will/should lock when a fall is taken. They may be used to ascend rope during a rescue or climber assist. They are great belay devices for climbing walls, ropes and challenge courses where participants are belaying. Caution should be taken to back up novice belayers when they begin to lower the climber. Most of these belay devices are not recommended for beginner climbers and belayers. These assisted lock belay devices are best for reducing shock loads to the belay system when holding falls that generate extremely high loads (In excess of factor 1).
