Sena Nautitalk Open - Marine Mesh Intercom - Single

NTT-OPEN-01 Sena Nautitalk Open - Marine Mesh Intercom (Single)

The Sena Nautitalk Open is an open-ear bone conduction Mesh intercom headset for crews who need to stay in touch without blocking their ears. Sound is carried through the cheekbones, so you hear the skipper on the intercom and the winch, the announcement and the wake behind you at the same time. It is built for professional onboard teams: charter crew, marina staff, sailing schools and anyone working a shift on deck. Sold as a single headset.

Key Features

• Open-ear bone conduction: nothing in or over your ears, full awareness of what is happening around you
• Mesh Intercom 3.0 and 2.0: Open Mesh with 6 channels and virtually unlimited participants; Group Mesh for private groups of up to 24
• Swivel beamforming microphone: filters engine and wind noise; swivel it up when you are not talking
• Salt and sun rated: 72-hour saltwater spray tested, UV-resistant materials, IPX5 against spray and rain
• Light enough for a whole shift: 41 g on a flexible frame that sits under a cap or helmet
• Bluetooth 5.2: phone pairing plus over-the-air updates and configuration through the Sena Marine app

Works With

Nautitalk Open talks to other Nautitalk headsets on the same Mesh channel, so it mixes into a crew already running Bosun, Crew or Easy headsets. If you need a waterproof headset that floats, the Bosun is the one.

FAQs

Why is the range shorter than the Bosun? The Open is designed for communication across a vessel, not between boats. 200 m covers a superyacht from bow to stern with room to spare; if you need boat-to-boat range, look at the Bosun or N2R.

Is four hours enough? It is sized for a working shift. Charge it between watches over USB-C.
