The Expand Mesh system is engineered to give you true full duplex, crystal clear, hands-free wireless intercom communications in a marine environment. The Expand Mesh headsets are a step up from the 2Talk bluetooth headsets. They utilize Mesh technology; the latest wireless networking tech, which creates a web of connected headsets, where each headset acts as a node in an unlimited communication mesh. As a result, a system is not limited to just 2 or 4 headsets, but can connect virtually unlimited numbers of headsets. When using the Expand Mesh you can communicate hands-free with other Sena Mesh Intercom™ users up to 0.25 mi (400 m) away, or up to 1 mi (1.6 km) away with 6 or more users. The Expand Mesh features both Group Mesh Mode and Multi-Channel Open Mesh Mode, which supports 9 channels letting users switch between different groups on different frequencies. Sena’s Mesh platform offers flexibility by allowing users to come in and out of range while keeping the rest of the group connected without interruption Features: • Full-Duplex, Wireless, and Handsfree (full-time talking and listening) • No Push-to-Talk (PTT) buttons, cords, base stations, or belt packs • Full Digital Mesh Communication - No Master/Slave or pairing required • Fully Expandable - Unlimited number of headsets can be added • 9 Separate Mesh Communication Channels • Open Mesh or Private Mesh capability • Bluetooth 5.2 for connection to smart phones, Siri, MP3, etc. • Dual Stereo Earpieces - Listen to stereo music or mono intercom • Up to 500 Meter 2-way communication range (with 2 headsets) • Up to 1.1 mile range with 6 headsets minimum (using Mesh hopping) • Lithium Ion Rechargeable Battery (with included USB-C cable) • Up to 10 Hour talk time • Can be connected to 2-Way Ham, FRS, GMRS, or VHF radios (with separate adapter) • Fully weatherproof - Works rain or shine • Totally secure behind the neck design - can't be knocked off - glasses and lanyards are not a problem
