The Davis Spar-Fly Wind Indicator combines needle bearing balance, high impact plastic, and marine grade metals for exceptional sensitivity and durability. Spoiler holes in the vane reduce lift and increase accuracy. Spar-Fly is unaffected by angel of heel. Its V-shaped silhouette and bright red color can be easily seen from the deck. The adjustable nose weight offers fine tuning for the perfect balance. Can be top-mounted to a flat surface, or side-mounted with included bracket.
Replacement vanes (sold separately) are also available. Weighs only 1.25 oz. (35 g).
