Suggestions for a handheld wind meter
 
I did a search for handheld anemometers and they run the gamut from cheap to really expensive. Can anyone suggest one that you have found reliable, and on the low end of the cost spectrum, say, not more than $30 US. I was surprised at the reviews on Amazon with what seemed like a high failure rate of the less expensive ones. I know, you get what you pay for. :D
Still, maybe there are a few good cheap ones out there. I can always hope. :)

Afew of my freinds use a smart phone for wind speed at the field. For my self I have a small light weight ribbon on the antenna of my radio. I am always asked what direction the winds blowing at the ground by these same guys. If the wind is heavy at ground level you know it is much worse up above. For me if the wind is moving tree branches hard I go home.

If you have a smart phone this is the way to go.

I don't use a smart phone so that's out. I've been around long enough to know when it's time to either quit flying or don't start based on what I see, but I thought it would be interesting to have a definitive reading on the windspeed, a new toy to play with as it were.

Well this is the one that I have and I swear by it, had it for a few years and have never been let down by it. It is not int he price range you mention though. Sorry

The 1000 is a good base unit

Back in the mid 1980's I built up an anemometer out of a high quality brush type DC motor, a small fan, an analog meter (Calibrated to MPH) and a piece of 6 inch diameter tubing. Calibrated it against the digital speedometer on my pedal type bicycle. It's dead accurate. I spent about a dollar plus a junk box of parts for it. Still have it, still use it regularly.

And when those small hand held anemometers became available, my old piece of :censor: was compared to those professional ones. Found out at low wind speeds under about 10 MPH, at least one of those $100 professional units was off by a factor of two.

It's also been checked against our club house anemometer with the spinning cones. Dead accurate. I also designed and built a microcontroller LCD display for our club house anemometer that shows MPH and peak gusts. Its common to find those gusts hitting two or three times the instantaneous wind MPH. I finally had to replace the sapphire bearings inside this unit after some 5 years of operation outdoors. Cost about $15 or so.

This is very accurate, within a few percent. And, very rugged.

Before heading out to fly, log on to this:

Best wind forecast app I've seen yet.

The other thing you can do at the field even with out a smart phone is simply call the ATIS closest to your flying field. I call DFW ATIS for the wind direction, wind speed @ density altitude.

The one that yakfishingfool mentioned seemed too good of a deal to pass up so I ordered it today.
Thanks to all for your responses.

I've got one the same but mine came from Hobbyking: http://www.hobbyking.com/hobbyking/s...dProduct=23869

It works very well.
