Open water diving, on the other hand, is a form of underwater exploration that involves the use of scuba gear, including tanks, regulators, and buoyancy control devices (BCDs). It allows divers to venture deeper and stay submerged for longer durations compared to freediving.

Key Characteristics of Open Water Diving

  • Scuba Gear: Open water divers rely on scuba equipment to breathe underwater, granting them access to greater depths and extended dive times.
  • Certification: Open water divers typically undergo training and certification to ensure they can safely operate scuba equipment and navigate underwater environments.
  • Exploration: Open water diving often centers on exploring submerged wrecks, coral reefs, and marine ecosystems, offering a unique perspective on underwater landscapes.

Freediving in Open Water for Beginners

Now that we have a clearer understanding of open water and freediving, let’s explore the world of freediving in open water, particularly for beginners.

Freediving Basics

Breath-Holding Techniques

Freediving relies heavily on breath-holding techniques, and beginners must learn to control their breath efficiently. This involves proper inhalation, exhalation, and relaxation exercises to extend breath-hold times safely.


Equalization is a critical skill in freediving. It involves equalizing the pressure in the ears and sinuses as you descend. Failing to equalize properly can lead to barotrauma, which can be painful and even dangerous.

Safety Buddy

For safety reasons, freedivers should always have a buddy when exploring open water. A safety buddy can assist in case of emergencies and provide support during the dive.
