TecRec Course Technical-Diving-Philippines

Tec40 Course Outline -

The Tec40 subcourse of the TecRec ‘Tech Deep’ program is a limited, entry-level technical diving program that bridges the gap between recreational diving and full technical deep decompression diving. Certified Tec40 divers are qualified to make limited decompression dives using equipment that is more extensive than that used in recreational diving

All technical courses can be completed on sidemount configuration if combined with the Tec Sidemount course

Perfect for -

  • Recreational divers looking for entry into technical diving
  • Limited non-accelerated decompression, with one deco tank
  • Deco gas >50% O2

Tec40 Prerequisites -

  • Advanced Open Water Diver
  • Nitrox and Deep Diver
  • 18 years or over
  • 30 Logged Dives (inc 10x Nitrox & 7x >30m)

Tec40 Course Content -

  • Knowledge Development and exam
  • 3xPractical Applications
  • 4x Open Water Dives(3 cylinders)

Course Duration

4 days* with classroom, practical workshops and 4 dives

Day 1 – Classroom theory, equipment workshop and practical applications
Day 2 – Skills training dives 1 – 2
Day 3 – Classroom theory and practical applications
Day 4 – Technical dives 3 –  4

*A 5 day program is recommended if you prefer a more relaxed training program or more time to refine skills.

Pre-study of course materials/completion of knowledge reviews can shorten the course duration. This is highly recommended. You may obtain your own copy of the TecRec ‘Tech Deep’ manual in advance, or I can email handouts/reviews.

The course is performance based, not time based. Performance requirements for each section must be satisfied to allow progression and certification.

Proper decompression procedures keep technical divers safe

Tec40 Training Dives -

 Tec40 Equipment Requirements

  • Double cylinders of at least 12 l/70 cf each, with isolator manifold.
  • The isolator manifold is not required for divers using sidemount configuration.
  • Primary and secondary regulators for back mounted double manifolds, one
  • with two metre/seven foot hose for air sharing and one with SPG. Note: In sidemount configuration, one regulator must have the two metre/seven foot hose, and both regulators must have an SPG.
  • 1x Stage/decompression cylinder with regulator and SPG, with proper labels/markings.
  • Tec diving BCD(s) and harness (backmount or sidemount)
  • Two multigas enriched air capable dive computers, or one multigas enriched
  • air computer and a back up single gas computer with dive tables, or one single gas enriched air computer and a backup timer and depth gauge with dive tables.
  • Exposure suit appropriate for environment and dive duration
  • Weight system (if needed). Note: Students and staff should weight for the contingency of decompressing with near-empty primary cylinders and empty or absent stage/deco cylinders
  • Jon line (as needed for environment)
  • Inflatable signal tube, whistle and/or other visual and audible surface signaling devices. Note that a sausage type DSMB may double for the inflatable signal tube.
  • Reel and lift bag (bright yellow preferred) or DSMB. A suitable DSMB has sufficient buoyancy to help steady a diver during a drifting decompression, and is unlikely to spill when deployed from the underwater.
  • Knife/cutting device and back up
  • Slate
  • Back up mask (optional)
  • Compass
  • Lights (optional – as required for dive environment)
  • Backup buoyancy control – the 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)

Assessment of Technical Dive Training Readiness

In preparation for the course and before beginning open water dive training, there will be an informal assessment of the potential student’s skills and comfort level in water, along with a general assessment dive knowledge. If the potential student appears to lack dive readiness appropriate for the training level, remedial training will be offered before training progresses.
