Anemometer accuracy #4

I'm a bit concerned about the current 'home AWS' style anemometer. I can't say I feel like it will be up to the test of measuring gusting winds around 80 km/h on big fire weather days, or 100+ if @joshuass takes them out for storms.

The other point is that we need to have them 'looking clean and professional' if we want to be promoting their use within the fire agencies, and they cheap looking plastic doesn't exactly scream hi-tech.

The option I'm currently looking at is this: http://www.davisnet.com/product/anemometer-for-weather-monitor-or-wizard/

Same sensor as the Davis systems with a horizontal bar to mount. This could allow for quick north alignment.

At a cost of $145, they would be by far the most expensive component, but it's arguable that they need to be and the total cost would still be less that $200 (hopefully)- keep in mind that this is still cheaper than a GoPro!!

The other option is doing a little more research in to marine anemometers for yachting at that sort of thing. e.g http://www.nuevonova.com/simrad-is20-wind-mast-head-unit/ or http://www.airmar.com/productdescription.html?id=156 (though quite expensive, you get the idea.)
