More on Underwater Compass
Underwater compasses are essential for navigation on dives where visual landmarks are limited. They help divers maintain a bearing, return to a starting point, or follow a pre-planned route—especially in low visibility or sandy environments. Compasses may be worn on the wrist, attached to a console, or clipped to gear. Proper training in compass use includes learning to account for current, drift, and kick cycles while swimming a heading or reciprocal course.
