Training: Underwater navigation
Underwater navigation is a crucial skill for any diver, allowing them to safely and efficiently explore the underwater environment. One of the most important tools in underwater navigation is the compass, which is used to determine direction and help divers stay on course. In addition to using a compass, divers can also use natural references such as the sun and the sea floor to navigate. When diving, it is important to first familiarize oneself with the compass and how it works. A compass is a device that uses a magnetized needle to indicate magnetic north. The compass should be adjusted for magnetic deviation before diving, which is the difference between magnetic north and true north. This can be done by using a deviation card, which can be found in most diving manuals. Once familiar with the compass, divers can begin to navigate using it. One of the most basic methods is to use the compass to determine direction, and then swim in a straight line towards a specific destination. This...
