TecRec 45

What is it?

The Tec 45 course picks up where Tec 40 leaves off . Building on the Tec 40 program, the Tec 45 module covers the skills, equipment and planning needed to dive to a maximum of 45 metres/145 feet.

What Will we do?

  • Use decompression software and dive computers to plan and execute single and repetitive decompression dives not deeper than 145ft. (no time limit to amount of decompression)
  • Use a single cylinder of decompression gas of EANx or oxygen to accelerate or add conservatism to the decompression stops
  • Learn to prepare for and respond to foreseeable technical diving emergencies.
  • Master the basic skills and procedures you’ll need as you move into deeper technical diving

How long will it take?

  • 3-4 days
    • 8 Hours (minimum) classroom and practical
    • 1 Confined or limited Openwater dive (8-30ft)
    • 3 Openwater Dives (40-145ft)


  • PADI Rescue Diver or equivalent
  • First Aid and CPR within the past two years
  • PADI Tec 40 certification (or equivalent)
  • 18 years old
  • Obtain a dive medical signed by a physician

If not Tec 40 Certified:

  • 50 logged dives with:
    • 12 dives were made with enriched air Nitrox deeper than 18 meters/60 feet
    • 6 (with or without EANx) dives were deeper than 30 meters/100 feet


  • Double cylinders of at least 70cf each, with isolator manifold (not required for sidemount).
  • Primary & secondary regulators for back mounted doubles, one with seven foot hose, and one Submersible Pressure Gauge (SPG). Sidemount: One seven foot hose and two SPGs.
  • 1 Stage/decompression cylinder with regulator, SPG, mounting hardware and proper labeling/markings. (O2 clean prefered)
  • BCD and harness – backup buoyancy control*
  • Depth gauge/computer and backup depth gauge/computer
  • Timing device and backup timing device (can be included in above)
  • Exposure suit appropriate for environment and dive duration.
  • Weight system (if needed)
  • Jon Line
  • Surface Marker Buoy (SMB/DSMB)
  • Surface Signaling device (whistle, mirror etc.)
  • Reel/Spool (100ft min)
  • Lift bag 100 lb. lift (min)
  • Knife/cutting device and backup
  • Slate
  • Backup mask
  • Compass
  • Primary Dive Light
  • Back up Dive Light
  • Oxygen Analyzer (instructor may supply)

* Student must have a reliable means for controlling buoyancy and maintaining decompression stops in midwater with a failed primary BCD. This is usually accomplished with a backup BCD (double wings) or dry suit.

Price Include:

  • Certification
  • Gases
  • 2 – boat charters

Students are responsible for: *

  • All Equipment to include tanks
  • Dive Accident Insurance

* Traveling to Honolulu or missing equipment? Discuss with your instructor.
