Learn how to manage 4 tanks

If you’ve looked into technical diving, you realize that tec divers always wear more than one tank. Sidemount is an increasingly popular way to configure multiple cylinders for technical diving. You can enter the world of tec diving with the Tec Sidemount Diver course and apply what you learn to other TecRec courses. Your instructor may offer to integrate this course with the Tec 40

  • Gain insight into basic tec diving techniques
Learn How to
  • Gas matching procedures to include dissimilar volumes
  • Gas management utilizing independent cylinders
  • Psychological considerations of technical diving
  • Equipment considerations including:
    • Cylinder options

  • Problem solving in a sidemount configuration
  • Diving in tight or confined spaces
  • Conservation
  • Water entries/exits
  • S-drills specific to sidemount diving
  • Some of the required skills you will have to demonstrate include:
  • Demonstrate various propulsion techniques such as the frog kick, modified frog kick, modified flutter kick, backwards kick, helicopter turns, and hand pulling if appropriate for the environment.
  • Demonstrate adequate buoyancy control; ability to hover at a fixed position in water column without moving hands or feet
  • Demonstrate adequate trim; ability to maintain proper position during the descent, bottom, and ascent portion of the dive
  • Demonstrate the ability to perform the following exercises while maintaining trim and buoyancy in the water column:
    • Unclipping and attaching sidemount cylinders
    • Perform gas switches with and without a mask
  • Demonstrate the ability to safely manage gas in independent cylinders
  • Demonstrate conservation, awareness, and back referencing techniques
  • Deploy a lift bag
