Ghost

Ghost descender is a  multiuse device. It can be used both with one or two ropes from 7,5 to 10,5 mm diameter.
It allows dinamic belay to the leader and self-locking belay to the second (indipendent if the seconds are two). It works very well for rapelling. It allows lowering and lifting manouvres simply rotating the device. It is reccomended the use of HMS connectors.
