Discover Technical Diving

Course Outline

The PADI Discover Technical Diving course is a bridge from recreational to technical diving. It exposes recreational divers to tec diving and entry level tec diving skills and equips them with the information they need to decide whether or not to accept the additional risk and commitment that PADI Tec courses demand. The PADI Tec Basics course runs within recreational limits, using segments from PADI Tec 40 Dives 1 and 2. The course allows PADI Tec Deep Instructors to have students practice fundamental tec skills before enrolling in the PADI Tec 40 program. The course also recognizes students who choose not to continue their technical training.

Discover Technical Diving Course Credit

Since the PADI Tec Basics Distinctive Specialty is actually a portion of the PADI Tec 40 course, Tec Basics may credit toward this certification.

At the instructor’s discretion, the Tec Basics student may choose to move up to PADI Tec 40.

The instructor may request a repeat of some confined water sessions and practical application sessions, depending on the interval between Tec Basics certification and the start of the PADI Tec 40 course.

Tec 40 Training Dive One,Practical Applications One and Two and Knowledge Development One and Two may be credited towards the
PADI Tec 40 Diver if all performance requirements have been met.

Credit towards Tec 40 Diver is valid for 12 months from the completion of the Tec Basics Distinctive Specialty.

Confined Water Skills (two primary and one stage/deco cylinder)

  • Working in a team, assemble and inspect the basic technical diving rig following the taught rigging philosophy and to meet individual/environmental needs.
  • Demonstrate the proper weight required for the dive.
  • Demonstrate neutral buoyancy while wearing the basic technical dive rig underwater in water too deep in which to stand by hovering for 1 minute without sculling or kicking.
  • Within 30 seconds, independently close the cylinder valve to a regulator that is experiencing a simulated free flow.
  • Assist a team mate by closing the correct valve to a regulator that is experiencing a simulated free flow.
  • Within 30 seconds, independently close the isolator valve in response to a simulated manifold leak. This skill is not required if using sidemount configuration.
  • Respond to a simulated out of gas emergency by signalling a team mate, switching to the teammate’s long hose second stage, then swimming 30 metres/100 feet using the long hose regulator and maintaining contact with the team mate.
  • Respond to a teammate’s simulated out of gas emergency by, on signal, providing the teammate with the long hose second stage, switching to the short hose secondary, then swimming 30 metres/100 feet as the teammate uses the long hose regulator, maintaining contact.

Open Water Dive (two primary and one stage/deco cylinder)

  • Working in a team, plan the dive following the A Good Diver’s Main Objective Is To Live procedure, and perform predive checks following the Being Wary Reduces All Failures procedure.
  • Working in a team, perform a bubble check, descent check and S-drill.
  • Independently don, remove and re-don a stage/deco cylinder on the bottom.
  • Perform gas switches to stage/deco cylinders correctly following the NO TOX procedure.
  • Shut down both manifold valves and the isolator valve, and switch second stages to maintain a breathing supply, beginning with any valve chosen by the instructor, within 60 seconds (or within 40 seconds if there is no isolator valve).
  • Deploy a lift bag or DSMB from the bottom in water too deep in which to stand.
  • Swim at a steady pace at a constant depth for sufficient time to determine the SAC rate.
  • Using only neutral buoyancy, maintain a simulated decompression stop for eight minutes.
  • Remove and replace stage/deco cylinder at the surface in water too deep in which to stand
