Better stabilization, accuracy and defense against crosswind
Does not have a helical twist to catch air
The Nockturnal Helios Lighted Vanes are the world's first lighted vane system. This combination of a lighted nock and lighted vanes offers better stabilization, visibility, more RPMs, accuracy and defense against crosswind. Slips over the shaft to illuminate vane. The six-vane system is composed of three sets of two vanes curved towards each other and has an airfoil design. This allows them to spin quickly and reduce noise because it does not have a helical twist to catch air. Simply slide over the back of your arrow, align with supplied Helios Nock turn-off hole and apply a bead of fletching glue to secure. 1-1/8" dia. makes clearance from drop-away rests much easier to achieve and works with all shoot-through rests as well. This size will fit arrows with an S Nock. Per 3. Made in USA. Avg. wt. with lighted nock: 54 gr. Available: Standard Nock. Colors: Green, Red.
