The OS Series: 3
The original and iconic ‘big yellow timer’ is still the top choice for competitors around the world today. If you need a robust timer, with an easy-to-read display, and exceptional sailing functionality, then this is the one for you. The OS3 can be strapped to a mast or comfortably worn over your sailing kit. The face rotates to give you the best viewing angle and the big buttons mean you won’t be left fumbling when the race is about to begin. The OS3 also features our essential sync button, which synchronises your countdown to the race control timer, ensuring you won’t miss the gun.
