Underwater Navigation
Underwater navigation involves finding your way while underwater, typically using methods and tools suited for the environment. Divers often rely on natural landmarks, such as coral formations or the ocean floor, to guide them. They may also use underwater compasses and dive computers that provide information on depth and direction. Another technique involves using a method called "dead reckoning," where divers track their distance and direction based on last known points. Understanding currents and visibility conditions is crucial, as these factors can significantly affect navigation and safety while exploring underwater.

Underwater navigation refers to the techniques used by divers and submarines to determine their position and direction while submerged. Unlike surface navigation, underwater navigation lacks visual landmarks. Divers often rely on compasses, underwater maps, and natural references like currents or topography. Advanced technologies like GPS can be used from the surface or with specialized equipment. Divers also employ navigation patterns, such as swimming in a straight line or using a "U" shape, to keep track of their route. Understanding buoyancy and underwater visibility conditions is essential for safe and effective navigation beneath the surface.
