Yes, I'll have to look into it. Fun to play with those features! Still, it won't correct for deviations caused by the bad air.
Not to get too technical, but all modern marine wind systems use sophisticated damping algorithms to greatly reduce that effect. It introduces a small amount of hysteresis, but thats an OK tradeoff.Not to get overly technical, but the wind vane on the electronic sensor is only 6 inches long and has low rotary inertia. Thus it responds rapidly to turbulence with very little damping, which results in the display in the cockpit exhibiting rapid oscillatory motion which is difficult to "average" optically. My windex is 16 inches long and damps out optically the small turbulence induced oscillations due to the distance from the eye. So I see a much more stable direction cue than if I had glanced at the Raymrine display. YMMV.
That's what I thought too. I looked in the manual last night and could not find a reference to it. There was reference to calibration and dampening options if the boat has the H5000 Computer installed. There may be an option for how often the angle and windspeed are updated, say every second, every 5 seconds etc. That will take some of the variation due to turbulence out of the reading.A damping factor can often be applied in the software of the instrument to hide those small oscillations. I know there's an option for that in our B&G menus, so I presume Scott's has it too.
I wonder if you would have to wire it backwards to get the proper wind direction?Yes, I'll have to look into it. Fun to play with those features! Still, it won't correct for deviations caused by the bad air.
Or maybe one must sail astern....I wonder if you would have to wire it backwards to get the proper wind direction?
Maybe in Australia it would work that way.
Well, no. The instrument has a setting where you tell it to adjust 180 degrees. You can mount it sideways and adjust it 90 degrees if you want!I wonder if you would have to wire it backwards to get the proper wind direction?

Check the Installation manual instead of the Owners manual. Our current Zeus3 and previous NSS8 both mention the option there.That's what I thought too.

You have to remember it’s not turbulence. It’s a angle deflection and speed delta based on apparent wind speed and angle. Turbulence might oscillate around a mean, and you could null all that out. Deflection you can’t.That will take some of the variation due to turbulence out of the reading.
I did a survey here at this marina, all the sailboats have them facing forward. Four ospreys in the trees across the creek but not interested with sitting on mastheads. I just did a list for repairs when we haul next week and transducer fixing is on it.Well, no. The instrument has a setting where you tell it to adjust 180 degrees. You can mount it sideways and adjust it 90 degrees if you want!
So, based on recent comments, it seems like I will leave it alone!
Thats actually an Airmar product.Cheaper to buy this weather station, wind, direction, humidity, temperature, and GPS. https://www.weathershack.com/product/new-mountain-nm150wx.html
And no little whirly cups for birds to break.
