Equipment
Various pieces of equipment have developed to assist divers navigating underwater.
- Magnetic compasses, set either in a diver's console or wrist mounted. Various forms exist.
- Scuba sextant, or Nav-finder, to enable a diver to plot an ongoing course during a dive.
- Compass boards
- Hand-held sonar
Periodically reports are issued suggesting the development of underwater GPS technology, but no system is currently available on market. It is generally thought that the difficulty of locating satellite by signals from underwater at present is not capable of being overcome by existing technology.
