Scuba Basics

Scuba certification involves classroom work and in-water practice. The in-water practice will give you hands-on experience with scuba equipment and there are some important concepts you will need to learn in order to dive safely. These include:

  • An understanding of air, what it is composed of and how your body uses it
  • Understanding air pressure and the physics of diving
  • Understanding air consumption
  • Understanding the physiological processes which occur when breathing pressurized air, including ingassing and outgassing
  • learning the risks involved in recreational scuba diving
  • health concerns and strategies for planning repetitive dives
