Course Outline

Tec Sidemount offers the same benefits as the PADI Sidemount Diver course but gives you the opportunity to dive with 2+ cylinders for extended dive times. 

The Tec Sidemount Diver course is a great way to get started into technical diving because the skills you learn in this course will train you to handle multiple cylinders on a single dive. You can combine what you learn in the Tec Sidemount Diver course with other open-circuit tec courses that you take, or certifications you’ve already earned, to take advantage of sidemount’s cylinder configuration and handling advantages.

You will:

  • Don and doff their sidemount cylinders whilst in the water. 
  • Conduct a buoyancy check at the surface. 
  • Donor and receiver to an out of air diver. 
  • Switch regulators to keep gas balanced in their independent cylinders. 
  • Neutral buoyancy swimming using various finning techniques. 
  • Valve shutdowns exercise combined with gas switches (safety drill). 
  • Twin partial cylinder removal and swim neutrally buoyant. 
  • Neutral swim with one cylinder removed (hand-held). 
  • Simulate a regulator free flow and breathe from regulator using (valve fluttering). 
  • Maintain the correct trim of the sidemount cylinders (especially when buoyant). 
  • Sidemount bungee failure, replace with spare.
