Why Saltwater Makes You Float – Buoyancy Explained for Beginner Scuba Divers

Описание: Why are objects more buoyant in saltwater vs freshwater? This is one of the most important scuba diving buoyancy principles beginner divers need to understand.

In this video, Marcel van den Berg, a PADI Platinum Course Director at Sairee Cottage Diving on Koh Tao, Thailand, clearly explains the science of buoyancy for scuba divers. You’ll learn why saltwater provides more lift than freshwater, and how this affects your weighting, buoyancy control, and dive performance.

When an object is neutrally buoyant, it displaces a volume of water equal to its own weight. But saltwater is denser than freshwater, so the same object displaces heavier water in the ocean—making it float. Understanding this concept is vital for safe, confident diving.
