Diving Girl

• Air sharing – the act of multiple divers sharing one air supply.
• Buoyancy – the right buoyancy allows the diver to move about underwater comfortably. Amount of equipment, buoyancy compensators, and amount of air in the lungs all come to play in maintaining buoyancy. More air in the lungs makes for more buoyancy, while less air makes for less buoyancy.
• Diving signals – diving signals may vary, but its purpose is to be able to communicate with other divers. It should be clear among a group of divers what the diving signals to be used are before the dive.
