A buddy line is a line or strap physically tethering two scuba divers together underwater to avoid separation in low visibility conditions. [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.
Discomfort or stress injury related to weight distribution and support. A weight belt hanging from the small of the back of a horizontal diver to counteract suit buoyancy spread over the full length of the diver can cause lower back pain. When walking on land before and after a dive, the weight belt may exert painful pressure on the hip joints.
The dive is turned when the first diver reaches one third of the starting pressure. [19] However, when diving with a buddy with a higher breathing rate or a different volume of gas, it may be necessary to set one third of the buddy's gas supply as the remaining 'third'.
The buddy check is a procedure carried out by scuba divers using the buddy system where each dive buddy checks that the other's diving equipment is configured and functioning correctly just before the start of the dive. [1] A study of pre-dive equipment checks done by individual divers showed that divers often fail to recognize common equipment ...
The diver's mass on a typical dive does not generally change by what seems like much (see above—a typical dive-resort "aluminum 80" tank at 207 bars (3,000 psi) contains about 2.8 kilograms (6.2 lb) of air or nitrox, of which about 2.3 kilograms (5.1 lb) is typically used in a dive, although any air spaces such as in the BC and in diving ...
Diving with a buddy is known to be competent and who can be trusted to behave responsibly. [62] Training to deal with emergencies and rescue. Carrying equipment to be independent of the buddy in most emergencies. In some circumstances it may be safer to dive without a buddy. [63] Overweighting Difficulty in neutralising and controlling buoyancy.
In solo diving, a buddy bottle is a bailout cylinder carried as a substitute for an emergency gas supply from a diving buddy. A bailout cylinder for recreational scuba diving is often a small cylinder, known as a pony bottle , with a normal scuba regulator set, or a smaller cylinder with a combined first and second stage integrated with the ...
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 .
