C.A.M.P. belay devices are light and simple. The Shell is most suitable for general belaying. The Ovo excels on multipitch lead climbing where it can be rigged to auto-block belays for one or two seconds (the Ovo Kit includes all of the mandatory gear for this configuration). Every C.A.M.P. belay device is designed to easily manage double rope rappels with a wide range of rope diameters.
