I gave up a long time ago. It's not a linear adjustment. i.e. On my boat
between approximately 4.5 - 5.5 Kts. it matches the SOG. Below 4.5 its
reads low. Above 5.5 it reads high.
I'm not really sure how this can be as the the little spinning wheel is sort
of a generator. The faster it spins, the higher the voltage it will put
out. The output voltage is scaled to Kts. It should be a straight forward
calibration, but it is not. As I said, I gave up. I just use the SOG since
I'm on a lake.

PS Moving to Las Vegas tomorrow. The boat will follow in Jan. or Feb.
depending when I get a slip at Lake Mead. (4-5 month waiting list)
