Why Do We Teach This?

Sharing airWhy do we teach air sharing this way? For several reasons — chief among them:

  • It gets air to the out-of-air diver faster. Having to hunt for a an alternate-air-source second stage to give to another diver wastes time.
  • It works with both conventional “octopus” alternate-air-source second stages and integrated alternate-air-source inflators, such as the SeaQuest Air Source. Thus, students need only learn one procedure that works with any alternate air source configuration.
