Windex alternative..Help
 
Recently saw a windex alternative in a magazine, It looked like a GPS antenna with no moving parts. Had an opening through the middle that sensed wind direction and speed as the air passed through the opening. Looked pretty cool. I think it also had a temperature sensor built in but not sure of that part.. Anyway, I have been trying to find out more info and cannot now remember the manufacturer or what it was even called. I've so far been frustrated in my web search. Anyone seen this wind sensor before? I need a link to further info if you know who makes it. Anyone out there who has installed one of these and can provide feedback or review would be nice.

Thanks,
Steve

Also, the other real problem with those that I see, if the electrical system fails, you don't even have the physical indicator to look at. If a TackTick or Raymarine wind instrument fails, for lack of electricity, wiring issues, etc... you can still look up at the masthead and see what the wind angle is. :D

And here I thought a Windex alternative was a plastic disc on a stay, two lines on the disc representing the maximum pointing angles, and a fluttering piece of cassette tape below the disc showing the apparent wind angle. Oh, hell, forget the disc...the tape alone is probably enough.

Here's another: http://www.airmar.com/

As the guy at my nearby electronics dealer said " I could set you up with a suite of ST60 instruments for the cost of the ultrasonic mast top transducer alone"

Why invent the wheel???

Just get a windex and get it done...remeber, it indicates apparent

what's wrong with cassette tape?

I use silk tapes, they last longer
