The Plumett NS50 can deploy a climbing line and grappling hook to a height of 30 metres without making the explosive noise that is normally emitted by air powered devices. Designed for covert operations it is particularly useful in urban environments and in mountainous regions where echoing noise attracts attention.
It can also be used by swimmers as it is submersible to a depth of 30 metres and can withstand immersion in seawater.
