Anemometer Options [RE-wrenches]

[David Blittersdorf]

A plug for my companies products. We make professional wind measuring equipment 
for the wind energy industry.  Check out the Wind Explorer for data logging for small 
wind turbines. I have one on my 10kw Bergey and install one on all the 10kw turbines 
we help install. The anemometer is rugged and low cost ($85.) and lasts for many 
years. Our equipment carries a 2 year warranty.

I have been in the wind energy measurement business for over 20 years and there is 
alot of junk out there. We have not pushed our products in the homeowner side of the 
wind business as there is resistant to paying for quality products. You will not have 
buyer's remorse with our products. Check out our web site.
