TecRec 40

What is it?

This course introduces divers to limited decompression diving within accepted recreational depth limits (130ft). The course should be complete Technical diving equipment if you wish to continue on through the Tec 45 and Tec 50. However, it is easy to accommodate divers interested in very limited technical diving since the Tec 40 equipment requirements are only a bit beyond the standard recreational rig.

What will we do?

  • Use decompression software and dive computers to plan and make decompression dives with not more than 10 minutes of total decompression and not deeper than 130ft.
  • Use a single cylinder of decompression gas up to 50 percent oxygen to add conservatism to the required decompression
  • Learn how to calculate your Surface Air Consumption and apply that to Gas supply requirements.
  • Learn the techniques and procedures that apply to Technical Diving
  • Learn proper emergency procedures.

How long will it take?

  • 2-4 Hours classroom and practical
  • 1 Confined or limited Openwater dive (8-33ft)
  • 3 Openwater Dives (30-130ft)

Prerequisites:

  • Be a PADI Advanced Open water diver (or equivalent)
  • Be a PADI Deep Specialty diver (or equivalent)
  • Be a PADI Enriched Air diver (or equivalent)
  • Have a minimum of 50 logged dives, of which at least
    • 10 dives must be on enriched air
    • 12 dives must be deeper than 18 meters/60 feet
    • 6 dives must be deeper than 30 meters/100 feet
  • Obtain a dive medical signed by a physician

Equipment Needed:

  • Double cylinders of at least 70cf each, with isolator manifold (not required for sidemount).
  • Single cylinder confguration options:
    • A single cylinder with a dual outlet valve (H valve or Y valve)
    or
    • A single cylinder with single outlet valve and a bailout cylinder.
  • 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.
  • BCD and harness – backup buoyancy control*
  • Dive computers:
    – Two multi-gas dive computers capable of switching between all gases used during the course
    or
    – One computer with a dive timer (must display at least dive time, maximum depth, current depth and ascent rate) and a backup dive plan
    or
    – Two dive timers (must display at least dive time, maximum depth, current depth and ascent rate) with a dive plan and backup dive plan
  • Exposure suit appropriate for environment and dive duration.
  • Weight system (if needed)
  • Jon Line
  • Surface Marker Buoy (DSBM/SMB)
  • Surface Signaling device (whistle, mirror etc.)
  • Reel/Spool (100ft min) x2
  • Lift bag 100 lb. lift (min)
  • Knife/cutting device and backup
  • Wetbook/slate and pencil
  • Backup mask
  • Compass
  • Primary Dive Light
  • Back up Dive Light
  • Oxygen Analyzer (instructor may supply)
  • Dive planning software capable of planning all course dives

* 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:

  • E-Learning
  • Certification
  • Gases
  • 2 boat charters (if required)

Students are responsible for: *

  • All Equipment to include tanks
  • Dive Accident Insurance

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