Re: ST80 Shows No Difference Between True/ Apparent Wind
I don't know...but is this model pre-seatalk? Anyway, it sounds like someone disconnected the wire or connection to your knotmeter when they removed the mast and didn't replace it. I'd look for a dangling wire behind the unit display..it might be right there or if you have a junction box ( block) near the mast..where the wires connect when they enter the cabin.
