When developing the sync, Princeton Tec started with the proven foundation of the stable asymmetrical single arm bracket, integrated essential modes to please a wide variety of discerning users, and tied it all together with an easy to use Interface. Sync allows Direct access to a red LED, spot beam, and flood beam by a twist of the power dial. For those times that require max output a further rotation of the dial activates dual beam Mode - spot and flood at the same time.
