Requirements 45/50

Equipment Reguirements

Tec 45 and Tec 50 Equipment Requirements

 The following lists the equipment that is required (as noted) for the Tec 45 and Tec 50
 course. Students in the Tec 40 course may use this equipment, but are only required to use
 the equipment specific to the Tec 40 course listed above.
• Double cylinders of at least 12 l/70 cf each, with isolator manifold.
• The isolator manifold is not required for divers using sidemount configuration.
• Divers known to have a very low gas consumption rate may, at the instructor’s
 discretion, use lower capacity cylinders than specified here, provided the diver
 will have ample gas to assist a team mate in a gas sharing emergency.
• 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.
• Stage/decompression cylinder(s) (1 for Tec 45, 2 for Tec 50) 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 (if students will
 use dry suits, they should be trained/experienced in their use in recreational diving
 prior to using them for tec training or diving).
• Argon dry suit inflation system (as needed for environment)
• 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
 (double wings) or, when using light weight cylinders, the use of a dry suit is permitted.

Note: A lift bag/DSMB is not considered a reliable method of backup buoyancy control.
