2. Neutral buoyancy - Wikipedia

   en.wikipedia.org/wiki/Neutral_buoyancy

   Balance of forces on objects with negative, neutral and positive buoyancy A neutrally buoyant diver does not need to fin to maintain depth. In scuba diving, the ability to maintain neutral buoyancy through controlled breathing, accurate weighting, and management of the buoyancy compensator is an important skill. A scuba diver maintains neutral ...

3. Buoyancy compensator (diving) - Wikipedia

   en.wikipedia.org/wiki/Buoyancy_compensator_(diving)

   A buoyancy compensator (BC), also called a buoyancy control device (BCD), stabilizer, stabilisor, stab jacket, wing or adjustable buoyancy life jacket (ABLJ), depending on design, is a type of diving equipment which is worn by divers to establish neutral buoyancy underwater and positive buoyancy at the surface, when needed.

4. Diving weighting system - Wikipedia

   en.wikipedia.org/wiki/Diving_weighting_system

   They may be used by divers or on equipment such as diving bells, submersibles or camera housings. Divers wear diver weighting systems, weight belts or weights to counteract the buoyancy of other diving equipment, such as diving suits and aluminium diving cylinders, and buoyancy of the diver. The scuba diver must be weighted sufficiently to be ...

5. Diver trim - Wikipedia

   en.wikipedia.org/wiki/Diver_trim

   Scuba divers with good trim and neutral buoyancy. The trim of a diver is the orientation of the body in the water, determined by posture and the distribution of weight and volume along the body and equipment, as well as by any other forces acting on the diver. Both static trim and its stability affect the convenience and safety of the diver ...

6. Human factors in diving equipment design - Wikipedia

   en.wikipedia.org/wiki/Human_factors_in_diving...

   The material and pressure rating of cylinders affects convenience, ergonomics, and safety. Aluminum alloy and steel are the two commonly available materials that are most often used for scuba cylinders. Their strength to weight ratio allows the manufacture of scuba cylinders that are near neutral buoyancy when empty.

7. Doing It Right (scuba diving) - Wikipedia

   en.wikipedia.org/wiki/Doing_It_Right_(scuba_diving)

   Buoyancy compensator, which is adjustably positive, and compensates for the combined effect of the other equipment. In keeping with the minimalist philosophy, buoyancy compensators should be only as large as is necessary to provide neutral buoyancy at any point in the dive, and should allow easy, confident and reliable dumping.
