Diver navigation
(Redirected from Diving compass)
Diver navigation refers to the methods used by underwater divers to navigate underwater. It is a crucial skill in scuba diving, cave diving, and technical diving where divers must navigate through unfamiliar environments.
Overview
Diver navigation is often more challenging than navigation on land due to the unique conditions present underwater. These include limited visibility, the absence of familiar landmarks, and the three-dimensional environment. Divers often use a combination of natural navigation techniques and tools such as compasses and underwater navigation devices.
Natural navigation, also known as pilotage, involves using physical landmarks or features in the environment to navigate. This can include things like the direction of the sunlight, the slope of the sea floor, or distinctive features like coral formations or shipwrecks.
A compass is a common tool used in diver navigation. The diver sets a course on the compass and follows that course underwater. The compass can also be used to return to the starting point by reversing the course.
There are several types of underwater navigation devices available to divers. These include dive computers with built-in compasses, underwater GPS systems, and sonar-based systems. These devices can provide accurate navigation information and can be especially useful in conditions where visibility is poor or in complex environments like caves or wrecks.
Training
Training in diver navigation is typically part of basic scuba diving certification. Divers learn to use a compass, to navigate using natural features, and to estimate distance underwater. More advanced training is available for divers who wish to dive in more challenging environments like caves or deep wrecks.
