PADI Technical Diver 40/45/50 Courses

Technical (TecRec) diving means going beyond recreational scuba diving limits. But, TecRec divers will tell you that it’s really about the challenge and adventure of exploring places that no one else has ever seen. Tec diving is not for everyone, but it does attract experienced divers who want to go beyond their current limits and are willing to accept the added risks, training, investment and commitment it demands. If this is you, then PADI TecRec courses are your ticket to extreme adventure.

In technical diving the surface is often inaccessible in an emergency, so TecRec divers use extensive procedures, equipment and training to manage the added risks and potential hazards. Although founded on extensive open-circuit scuba technology, TecRec diving has been revolutionized by the development, availability and reliability of closed circuit re-breathers (CCRs). CCRs have numerous benefits and provide TecRec divers with significantly more time underwater.  


  • Diving beyond 40 meters/130 feet

  • Required stage decompression

  • Diving in an overhead environment beyond 40 linear meters/130 linear feet of the surface

  • Accelerated decompression and/or the use of variable gas mixtures during the dive

  • Use of extensive equipment and technologies

If you are interested in Technical Diving but not sure where to begin, give us a call at In2Deep or send us an email and we will schedule a time to meet with you to discuss the different tech diving possibilities to see what interests you the most.  

In addition, all certified divers participating in training are required to have Divers Alert Network (DAN) Diving insurance. Please provide proof of insurance prior to your class.

TEC 40:


PADI Tec 40 course introduces divers to limited decompression diving within accepted recreational depth limits. Although the student who clearly intends to continue through Tec 50 is encouraged to complete Tec 40 in complete tec diving gear, the limits of the Tec 40 qualification allow more flexibility. Therefore, to accommodate divers interested in very limited tec diving, the Tec 40 equipment requirements are only a bit beyond those of the standard recreational kit.




  • Certification as PADI Advanced Open Water (or equivalent)

  • Minimum age of 18 years old

  • Certification as PADI Enriched Air Diver (or equivalent)

  • Certification as PADI Deep 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 metres/60 feet

  • 6 dives must be deeper than 30 metres/100 feet

  • Have a medical form signed by your physician




Each section of the course will require 3-4 days of diving (including pool and open water sessions), 2-3 academic sessions, and 2 or more equipment configuration sessions.



Depth Range:

  • Dive 1: 0-30

  • Dive 2: 30-60

  • Dive 3: 50-90

  • Dive 4: 85-130




  • 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 40 metres/130 feet.

  • Use a single cylinder of decompression gas with up to 50 percent oxygen (EANx50) to add conservatism to the required decompression.

The Tec 40 course consists of knowledge development, three practical application sessions, one confined or limited open water dive, two open water no stop dives (simulated decompression) and one open water decompression dive.

Required Materials:

  • Tec Deep Crew-Pak

  • Key Skills Video

Required Equipment:

  • Double Cylinders at a minimum 72 cu ft each (more preferred)

  • Primary & secondary regulators for doubles

  • One with a seven foot hose for air sharing

  • One with an SPG

  • Stage/deco cylinders with regulator, SPG & staging kit properly labeled

  • Back-up deco gas as required

  • BC, back plate & harness (dual bladder wings preferred even with drysuit diving)

  • Dive computer (single or multi-gas), and either back-up computer or timer & depth gauge

  • Back-up decompression information (computer, dive tables, etc.)

  • Exposure protection (dry suit use requires prior dry suit diving experience)

  • Weight system (if needed)

  • Lights as necessary, including primary and backup

  • Jon line (for current diving environments)

  • Safety reel

  • (2) Slates, (1 wrist-type)

  • Compass

  • Z-knife and back-up cutting device

  • Spare clips, pull-ties, tank wrap bands & other rigging accessories

  • Back-up mask (optional)

  • Lift bag (100lbs min)

We look forward to getting In 2 the Deep with you!
