Raymarine Wireless Wind Kit including Heading Sensor for STNG

Best of all, when the sun comes out, the integrated solar panels automatically recharges the built-in battery pack. With no wires inside your mast, you’ll benefit from a much simpler installation and reduced weight up high in your rig. The T120 wind transducer also offers a performance increase over conventional wired transducers with improved response and increased accuracy.
Also included is Raymarine’s award-winning EV1 Evolution Heading Sensor. The EV1 is entirely self-calibrating and measures the movement of the boat with is 9-axis sensor system. With its built-in Evolution R4 software, the EV1 further refines the values for wind speed, wind direction, course over ground, speed over ground and cross track error by calculating out the detrimental effects of vessel yaw, pitch, roll and heel on these values.
It also provides an ultra-stable heading and position source for other onboard electronics including autopilots, radar systems, chart plotters and instruments. Finally, the included Wireless Remote Display enables you to calibrate the system and see all of your instrument data from anywhere onboard.
Small and portable, the remote can be worn on a lanyard, or snapped into its included storage bracket and used like a fixed instrument which can display any data item including data history as a line graph. Like the masthead transducer, the Remote Display is also solar powered and recharged by the sun.
