I thought I'd ask the group for any experiences with non-mechanical (no
bearings, roating cups etc) wind transducers. The technology seems
reasonably well established (ultrasonic, heated wire etc) in commercial
and military applications and there are a couple of ones with NMEA
output as well as one with Seatalk as an output option. Has anyone had
any experience good, bad or indifferent with them and are there any
reliability issues with them?

Discussion seems to be a little off topic. Obviously nobody is using
one or has direct experience.

Summary:

Raymarine in spite of what Doug says does not have a non-mechanical
transducer for sale. If so part no please! Certainly nothing on their
web site.

Non-mechanical transducers are used in a number of commercial/military
applications but not prevelant in recreational boating.

My application is for a wind system to fit im with my Raymarine ST60
system. I have seen enough dud mechanical transducers to not want them
on my boat. Therefore I'll wait.
