What is TecRec Deep Diving all about?
Technical diving is scuba diving’s “extreme” sport, taking experienced and qualified divers far deeper than in mainstream recreational diving. Technical diving is marked by significantly more equipment and training requirements to manage the additional hazard this type of diving entails. Tec diving isn’t for everyone, but for those who hear its challenge call, the PADI TecRec courses are the answer.
The Tec Diver course is an integrated sequence of three subcourses: Tec 40, Tec 45 and Tec 50.
You can complete them continuously, or you can complete each level separately with a time span between them. This gives you learning efficiency, instructional integrity and schedule flexibility.
To qualify for training for Tec 40 you must:
- Have an Advanced Open Water Certification
- Have a Deep Specialty Certification
- Have an Enriched Air Nitrox Certification
- Have 30 logged dives including 10 deeper than 18m
What will I learn?
- Use decompression software and dive computers to plan and make decompression dives with no 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
To qualify for training for Tec 45 you must:
- Be certified as a Tec 40 diver
- Have 50 logged dives 12 deeper than 18m/60ft and 6 deeper than 30m/100ft
What will I learn?
During your training you will learn the skills and equipment and planning need to dive:
- There would be no time limit to amount of decompression
- Prepare for and respond to foreseeable technical diving emergencies
- Master the basic skills and procedures you’ll need as you move into a maximum of 45 metres/145 feet
- The knowledge to plan and execute single and repetitive decompression dives using a single stage cylinder of EANx or oxygen to accelerate or add conservatism to the decompression stops.
- Deeper technical diving
To qualify for training for Tec 50 you must:
- Be certified as a Tec 45 diver
- Have 100 logged dives 20 deeper than 18m/60ft and 15 deeper than 30m/100ft
What will I learn?
During the Tec 50 course, you
- Make actual decompression dives as deep as 50 metres/165 feet
- Use enriched air nitrox and/or oxygen for decompression
- Use desk top decompression software to create custom dive tables and plan your dives
- Qualify to make technical decompression dives independently
It is preferable that you bring with you your own personal mask, fins, boots and wetsuit, however, we can of course arrange for the rental of these items
· Double cylinders (minimum 12 litre/70 cubic feet each, with larger preferred) with isolator manifold
· Primary and secondary regulators, one with two metre/seven foot hose (approximately) for gas sharing, and one with SPG
· Stage/decompression cylinders with regulator, SPG, mounting hardware and proper labelling/markings. Two per diver will be required
· Backup decompression cylinders as appropriate and required for the environment
· BCD and harness – redundant buoyancy control is required (double bladder BCD or dry suit if suitable for weight of equipment worn)
· Depth gauge/computer and backup depth gauge/computer
· Timing device and backup timing device
· Trimix decompression information (tables/trimix computer) and backup decompression information
· Exposure suit appropriate for environment and dive duration. (If you use a dry suit, you should be trained/experienced with its use in recreational and technical diving prior to using it for trimix training or diving.)
· Argon dry suit inflation or other inflation system as needed
· Weight system (if needed)
· Jon line (if needed for current diving environments)
· Inflatable signal tube
· Lift bag (bright yellow or per local community practice preferred)
· Dive knife / cutting device and backup slate, backup mask (optional)
· Compass, lights (optional)
