I'm having difficulty re-calibrating my Autohelm ST50 Wind instrument. In large part this is because I don't have the owner's manual. Raymarine don't show the manual on their website and haven't yet responded to my email enquiry.
Does anyone on this forum know how to calibrate the ST50 wind instrument? If you have the manual, could you send me a copy of the sections on operation and on calibration.
Calibration steps are available
