Where to see the Seatalk one option?

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?

I don't know that Raymarine makes one. But Ocean Radio has one that
purports to have a ST option. Look at this URL:

I have no real experience with them, but here are some thoughts about them
(in sailboat use).
-The technique seems to be where we are heading in the future. No movig or
wearing parts.
-On ships and in weather stations etc. this technique has been used for some
time.
-The ROWind would be very hard to calibrate when connected to most
instrument systems. One would have to go up in the mast and rotate the
transducer to get the thing calibrated.
-Most advanced (I don's know any that wouldn't) instrumet systems needs
propriatery wind transducers in order to be able to calibarte them from the
display. Also I do not know what
would happend to the true wind, one would probaly not get that.
