Tec45

TecRec Course Technical-Diving-Philippines

Tec45 Course Outline

The Tec45 subcourse of the TecRec ‘Tech Deep’ program introduces Tec 40 divers to the first stages of full, technical deep decompression diving. Certified Tec45 divers are qualified to make multistop decompression dives that employ EANx and oxygen for accelerated decompression.

The expectation is that a Tec45 diver intends to continue on in technical diving. Accordingly, the course not only develops the knowledge and skills to make open circuit technical dives as deep as 45 metres/145 feet, but also begins developing the knowledge and skills the diver will need at the Tec50 level and beyond.

Tec45 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 or Wetnotes
  • 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 mid-water 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.
