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.

Famous quotes containing the word equipment:
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
“At the heart of the educational process lies the child. No advances in policy, no acquisition of new equipment have their desired effect unless they are in harmony with the child, unless they are fundamentally acceptable to him.”
—Central Advisory Council for Education. Children and Their Primary Schools (Plowden Report)
“Pop artists deal with the lowly trivia of possessions and equipment that the present generation is lugging along with it on its safari into the future.”
