The Wireless Hull Transmitter converts the signals from connected depth, speed and compass transducers to wireless data used by Raymarine wireless Micronet instruments. Simple, color-coded connections allow for easy connection of sensors, while a built-in lithium battery allows the system to run for up to 300 hours on its own. Connect it to your boat's DC power system or charge using an optional solar panel.
For multihull vessels, install 2 Hull Transmitters and 2 sets of transducers in the boat and let Raymarine's advanced Micronet wind information determine which tack the vessel is on, for accurate depth and speed information even at all times.
