This may be attained by accurate variety of ballast fat, which needs to be the minimum to allow neutral buoyancy with depleted fuel supplies on the surface at the conclusion of the dive Unless of course You can find an operational necessity for better damaging buoyancy throughout the dive.[forty one]
The often quoted warning against Keeping a single's breath on scuba is usually a gross oversimplification of the actual hazard.

The breathing apparatus will generally enhance useless space by a small but important sum, and cracking force and flow resistance within the desire valve will induce a Web work of breathing increase, which can decrease the diver's ability for other do the job. Work of breathing along with the effect of lifeless Room could be minimised by respiratory relatively deeply and little by little.
