The TackingMaster is a wrist-worn tactical navigation device. It is ideal for regatta sailors in order to immediately recognise minor windshifts and course changes. No bigger than a wristwatch, you only a compass to adjust it on board. Simply set the wind direction and course. The TackingMaster provides tactical support for sailing into the wind and on broad reach courses, helps you find the correct side on the starting line and is easy to use. Comes with a wrist strap and a protective case.
