There was a Nexus multi (wind, depth, temp, speed) instrument on the boat when we bought it. We added a dedicated wind instrument and another multi at the helm. The new instruments matched right up with the old and work great. Nexus is owned by ComNav and they make the best autopilot around (favorite of the fishing fleet in PNW and Alaska). I'm going to install one to replace the old Autohelm 7000 that is dying on me.
