The St40 wind manual has a flow chart for user calibration.
It isn't at all obvious to me what the outcome of the "Align
Transducer" step is.

I'm hoping that someone out there has successfully aligned their ST40
or perhaps a benevolent Raymarine tech can advise.

I understand that the intent is to align the masthead sensor to the
boat, I just don't understand what reading I am meant to see on the
display after pushing buttons in some non-obvious way.

THanks in advance
