Made of high impact, grey plastic housing. Simply align front and rear sights on an object and read off bearing. Use to take a quick bearing or position set, determine angular gain or loss on the competition while racing, check distance offshore, establish lee-bow set while cruising or racing in currents, determine drift vector, and plot a line of position. The stable, liquid-damped compass card is graduated in 5� segments. Bold graduations every 15� for easy reading. Large, contoured handle designed for sure, steady grip and angled forward for added control. Lanyard and instructions included. Solid-state LED illumination system floods the compass capsule and sight vane with soft light. The LED will last for the lifetime of the compass. Batteries, which are included, will last up to 10 times longer than with regular bulbs. Average LED “half-life” is approximately 10 years if operated continuously. Positive “push-on” switching action, with vinyl boot water protection. Battery housing has high watertight integrity.
