first off:
I'm still trying to wrap my head around just how an instrument measures true wind speed on a moving boat. apparent wind I can grasp. as the comparison between gps speed and whatever is measured at an anemometer on the masthead. but true windspeed? huummm. Back when I was still flying hang gliders we had instruments that calculated your drift as you flew a steady circle, but that method doesn't seem too practical on a sailboat
.
second:
I've looked at the Garmin site, but don't see any accessory or referral to anything that I could add to my existing 43dv to give wind speeds. any recommendations? I'm not willing to spend a fortune but just looking at options. I need to get my manual out, but I'm sure even the small Garmin 43 communicates with other devices......... [edit] yup NMEA 0183 as well as NMEA 2000
