More on Underwater Navigation
Navigation is a vital skill for safe and efficient diving. It includes natural navigation using terrain features and compass navigation using headings and reciprocal bearings. Divers learn to recognize cues like sand ripples, coral formations, sunlight angles, and current direction. Compass skills allow precise travel even in featureless environments or poor visibility. Effective navigation reduces stress, extends dive enjoyment, and helps avoid surfacing far from the boat or entry point.
