overall do you recommend this anny?
I don't have it, but it's sounding like to me if uninterrupted data is important to you, a tradition back-up would be prudent.

i know. i am looking at a sonic for the few days when the traditional anny gets coated with freezing rain.
seems like this one is not heated so is a moot point.

maybe i am better with a 2ndary unit as the ecowitt sonic. cheaper to play around with and heated.
just lose the consolidated data in WU and weatherlink but manageable for those few days a year i guess.

I am not sure I would rely on it for a main/only wind set at this point. I am especially concerned about the low temperature specification. I have also seen a couple of phantom wind gusts in excess of 70 mph during prevailing winds of less than 20 mph. It was raining heavily, but hello, this is a weather station and should not be affected... #-o

I have it mounted on a ground mounted tripod with my ISS to see wind currents near the rain gauge. For that purpose it seems to be working well. For that matter, so did the regular VP2 wind set.

I got it more out of curiosity about sonic anemometers and I regard this as a test. I liked the direct connection to the ISS transmitter.

My main anemometer is a RM Young mounted on a mast well above the roof line.

How does your RM compares to the Davis mechanical anemometer?

See my website and click the Wind link in the navigation area. You can see charts and data comparing the two.

Any recent feedback from those who have purchased the Davis Sonic Anemometer? I purchased on earlier this year, but I'm strongly considering returning it to the seller. The unit periodically reports anomalous wind gust spikes when it rains. Unfortunately, that's when we are most likely to experience strong winds during heavy rainfall events. Given what I've seen, I have zero confidence in the reliability of the data when it's raining.

We're currently experiencing the effects of Tropical Storm Beta here in Southeast Texas, but it's really just a rain event. This is a 40 mph tropical storm at best, but just look at the wind gusts reported yesterday and today. I am 100% certain that the circled gusts are nowhere near the actual wind speeds at the time.

Seems to be a common flaw with a few "plate" type ultrasonics on the market.

Personally, there must be a reason why the 2D ultrasonics that cost thousands of dollars don't have "plates" for water to pool on:

and the fact wind direction, is also not horizontal.

...which is why even more expensive 3D ultrasonic anemometers also don't use plates. ;)

Unfortunately even the best of engineers haven't figured out a bird proof/wasp mud dabber/snow/freezing rain and drop proof device.

Nice to have a variety, of course.

for me the worst is a heavy, wet snow at a high rate, little wind around freezing temperatures.  Especially if the front moves through with sub zero F temps after to freeze the stuff on hard as rocks.

Also a widow maker with heavy stuff that needs shoveling.

Mother Nature can be cruel.
