Nockturnal was at the 2015 ATA Show in Indianapolis, Ind., for the release of its improved Helios Lighted Nock and Vane System. The Helios Lighted Nock and Vane System is designed to maintain its flight path as far as any other vane system on the market, even in a 25 mph wind. Featuring six angled vanes working in three groups of two, the Helios Lighted Nock and Vane System spins the arrow at 3,000 RPM to produce a much more consistent flight. Additionally, the smaller diameter arrow works to produce a better clearance to your rest. The Helios Lighted Nock and Vane System is available now with an MSRP of $34.99.
