The Cressi Compass with Strap and Hose Mount is a modern instrument that enables easy reading in all conditions. The magnetic compass card moves extensively in all directions, so that reading is accurate even if the instrument is not held perfectly level. The face is luminous and divided into 10° intervals. Reading can take place by looking at the instrument from above or, more easily, through a Gun-Sight Accurate special window that enables more precise tracking of your heading. Compass is equipped with a red lubber line for proper orientation. A rotating ratchet bezel with a double pointer for direction makes marking your heading and reciprocal heading quick and easy. A wide anatomical band, allows the compass to be attached to the wrist. Compass measures 2.36" (6 cm) in diameter, is 1.14" (2.9 cm) high and weighs 3.25 oz (92 g).
