I have had the masthead units repaired at Raymarine.
Not real cheap, but less than a new one

My ST60 wind instrument got hit by lightning, so I bought one from
Ebay. But it still does not work. It could be the mast head sensor.
Does anyone know if the sensor is reparable? If not is the sensor for
the Raymarine newer ST60 wind instrument compatible with the older
Autohelm instruemt?

Thanks,
