I am operating autohelm st30 speed, st50 echolot and st50 wind together. on the wind display , the wind direction shows only in the same direction, on windspeeddisplay shows the boatspeed in knots. i have no glue how it works.
SOURCE: autohelm st50 how to calibrate??? wind instrument
I had one. Don't think you calibrate it. Reading is relative to it's mounting base. To change the direction reading, you would need to rotate the base.
