WINDEX is the standard wind indicator around the world. Windex have a light, balanced vane with large fin area and low-friction SAPPHIRE jewel suspension. These features make the Windex respond quickly and accurately at wind speeds as low as 0.2 knots (0.1metre/second).
The tacking tabs can be adjusted to the apparent wind direction for port and starboard tacking. The Windex vane and tacking tabs feature reflective markers under the vane making them highly visible at night.
