How do you make a dive float?
Why do scuba divers float?
Buoyancy Control Diving
Breathing in and filling your lungs will cause you to float up a bit. While breathing out/exhaling and emptying your lungs will cause you to sink slightly. This is perfect when cruising over coral or a wreck at slightly different depths.
What do you call diving without a tank?
Freediving, free-diving, free diving, breath-hold diving, or skin diving is a form of underwater diving that relies on breath-holding until resurfacing rather than the use of breathing apparatus such as scuba gear.
