Description
spar-fly
spar-fly combines needle bearing balance, high impact plastic, and marine grade metals for unsurpassed sensitivity and durability. Spoiler holes in the vane reduce lift and increase accuracy. Spar-fly is unaffected by angel of heel. Easily seen from the deck because of its v-shaped silhouette and bright red color.
weighs only 1.25 oz. (35 g).
