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?
