The only true team event in freediving. Diver 1 descends, usually assisted by a stone or marble slab attached to a rope, while Diver 2 waits on the surface. Diver 1 reaches the target depth and is hauled to the surface by Diver 2 using only muscle power. No diving mask, suit or fins are permitted, only nose clip. Static apnea (STA) max. time
A single cylinder puts the diver in a position of dependence on the buddy for alternative breathing gas in case of an emergency cutting off the main air supply, unless the option of a free ascent is acceptable. Diving with multiple cylinders is done for three basic procedural reasons, or a combination of the three.

Free-flow diving helmets avoid the dead space problem by supplying far more air than the diver can use, and eliminating the oro-nasal compartment. This makes the whole interior of the helmet effectively fresh air, as it is adequately flushed during and after each exhalation at the cost of significantly higher gas usage in open circuit systems.
The diver is prohibited from using a dolphin kick; doing so will result in disqualification of the day's dive. [1] For AIDA International officiated freediving competitions, bi-fins was previously included under the umbrella term of constant weight (CWT) in competition. Prior to 2019, competitors wanting to use bi-fins in competition would ...
