Raymarine Hull Transmitter
Easy Installation - A typical installation can be done in just a few hours, with your rig in place and your boat still in the water. And there's no need for holes in the bulkhead or wires down the mast.
Self-powering - Solar powered with integrated lithium batteries that power the unit for life. Power consumption is so efficient that units can run autonomously for up to 300 hours.
Lightweight - The elimination of wires in the mast not only reduces spar weight but also lowers the boat's centre of gravity, giving significant and immediate performance advantage.
Portability - Using clip-in cradles, your display can be placed anywhere on your boat, allowing you to view the information where and when you need it.
Waterproof - Sealed for life and completely waterproof (submersible to 10m). This also means no condensation.
Raymarine Wireless for Racing - Receive and display precise data wirelessly from Hull and Wind transmitters, including polar data, true wind speed and angle, VMG and compass heading.
T121 Hull Transmitter.
For multihulls, advanced Micronet technology allows your displays to use wind direction to automatically determine which hull transducer supplies the information you need. No switches required.
Note: you need two hull transmitters for this configuration.
