As recently posted to the AWE list, a small kite on fine line can reach fairly high altitude. At little risk or cost the upper surface boundary wind resource can be directly sampled.

KiteLab, Ilwaco, WA, has assembled a quality system around a modified* Gomberg Pocket Sled and 300 m of added fine Spectra fishing line on a plastic winder, all stuffed in a small mesh pouch that fits a shirt-pocket. An included mini-carabiner and nylon-ribbon-strap lanyard allows anchoring to all kinds of objects.

The kite easily reaches about 700 ft altitude (with the usual strict precautions!). This is an astounding aviation capability in a pocket format for $30 USD.

* The modification replaces the double tail with a Y-bridle and a single tail. It is lighter and more stable.

Shipping is from Washington State, USA, paid by buyer.
Washington state sales taxes are included in the net price.
