The Sena NAUTITALK Bosun quad pack contains 4 marine mesh headsets for crew communication. Bosun is part of Sena's mesh range, not a separate network technology.

Communication on the water

Current specifications list Mesh Intercom 3.0 with six Open Mesh channels and Group Mesh for up to 24 participants. Published range is up to 800 metres on open water; actual coverage depends on conditions and user positions.

Shared channel or selected group?

Open Mesh is a shared conversation for compatible users on the same Mesh version and channel. Group Mesh is a closed conversation for selected members. On supported headsets you switch between these conversations, rather than hear both at once. Check the model manual for controls; do not assume CAST button sequences apply.

Microphone mute is supported: remain in the selected conversation and listen without transmitting your microphone audio. This is different from turning the intercom off.

For communication with legacy Mesh 2.0 products, Sena documents a Mesh 2.0 setting in the Sena Marine App. Check firmware, a common Mesh version and the intended mode before combining equipment.
