Weight belts are the most common weighting system currently in use for recreational diving. [17] Weight belts are often made of tough nylon webbing, but other materials such as rubber can be used. Weight belts for scuba and breathhold diving are generally fitted with a quick release buckle to allow the dumping of weight rapidly in an emergency. [7]

[37] A buddy line is commonly a short length of about two meters with a floating element between divers to reduce risk of snagging on the bottom. A buddy line is a means of communication.
Some dive computers have relatively large font displays, and adjustable brightness to suit the ambient lighting. [43] [44] [45] An open circuit breathing apparatus produces exhalation gas bubbles at the exhaust ports. Free-flow systems produce the largest volumes, but the outlet can be behind the viewports so it does not obscure the diver's vision.
The diver wears a full-face mask or helmet, and gas may be supplied on demand or as a continuous free flow. More basic equipment that uses only an air hose is called an airline or hookah system.

Pressure conversion between msw and fsw is slightly different from length conversion between metres and feet; 10 msw = 32.6336 fsw and 10 m = 32.8083 ft. [1] The US Navy Diving Manual gives conversion factors for "fw" (feet water) based on a fresh water density of 62.4 lb/ft 3 and for fsw based on a sea water density of 64.0 lb/ft 3 .
