Technical Diving
| The PADI Diving Science and Technology Tec Deep Course takes a diver from recreational to Full Tec certified diver, qualified to make multi-stop decompression dives using air, EANx and Oxygen with up to two gases for accelerated decompression. The course is divided into three sub courses. Tec 40, Tec 45 and Tec 50. |
 |
Tec 40
The Tec 40 sub course of the PADI DSAT Tec Diver course is a limited entry level technical diving program that bridges the gap between recreational diving and full blown technical deep decompression diving.
Certified Tec 40 divers are qualified to make limited decompression dives using equipment that is marginally more extensive than that used in mainstream recreational diving. Before starting the Tec 40 course, the diver must be:
1. Certified as an Advanced Open Water diver.
2. Certified as a PADI Enriched Air Diver
3. Certified as a PADI Deep Diver or show proof of at least 10 dives to 100 feet or more.
4. Have a minimum of 30 logged dives with at least 10 deeper than 60 feet.
5. Minimum of 18 years old.
This course is for divers that want to do extended range dives with 10 minutes or less of DECO using one stage bottle of EANx 40% or less for accelerated decompression.
Equipment Required
This course is designed to use most of the same gear you are using for your recreational dives with a few additions. You will need your mask and fins, BC(harness preferred) and:
1. A single high capacity cylinder with a Y or H Valve (available as rental) or a 30 cu ft pony bottle to be used as a second “back” gas.
2. Two (2) fully independent regulators. Primary (right post) regulator must have a 7 ft second stage hose.
3. Two (2) methods of determining your decompression requirements. Either two (2) dive computers or 1 computer and tables and a reliable timer.
4. Compass
5. Stage/Deco bottle of at least 30 cu ft with a regulator. This bottle will be attached to your BC Harness and must be rigged with straps and clips for easy mount and dismount.
6. Lift bags (2) and a reel.
Course Schedule
We will be covering theory for Tec Deep Decompression Diving including:
Technical diving risks and responsibilities
Equipment set up and use.
Gas planning EAD review, oxygen limits, SAC and gas supply planning, oxygen toxicity and exposure.
Emergency Procedure
Thinking like a technical diver.
Gas and decompression planning, desk top software.
Managing oxygen exposure ,CNS, OTUs
This course will include 3 classroom sessions, 1 pool session and 3 boat dives. These modules will be arranged to accommodate students and instructor.
Tec 45 Course
The Tec 45 course picks up where Tec 40 leaves off and takes your training as a tec diver further and deeper. It is the second subcourse in the full PADI Tec Diver course
What You Learn
The skills and equipment and planning need to dive to 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.
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 deeper technical diving
The Scuba Gear You Use
You use basic tec diving equipment
The Learning Materials You Need
You'll use the Tec Deep Diver Crew-Pak, which introduces you to:
-
tec diving lingo
-
emergency procedures
-
decompression and stage cylinder handling
gas planning
-
The pak includes a manual, dive planning checklist and dive planning slate. The optional Equipment Set-up and Key Skills video on DVD is a great tool to help you practice at home in between your tec diving adventures. You'll continue to use the Tec Deep Diver Crew-Pak through the Tec 50 course.
Prerequisites
You must be:
A PADI Advanced Open Water Diver (or hold a qualifying certification from another organization)
A PADI Rescue Diver (or hold a qualifying certification from another organization)
A PADI Enriched Air Diver (or hold a qualifying certification from another organization)
A PADI Deep Diver (or hold a qualifying certification from another organization)
PADI Tec 40 (or hold a qualifying certification from another organization)
Have a minimum of 50 logged dives, of which at least:
- 12 dives were made with enriched air nitrox deeper than 18 metres/60 feet
- 6 (with or without EANx) dives were deeper than 30 metres/100 feet
At least 18 years old
Have a medical statement signed by a physician
Tec 50 Course
The Tec 50 course completes your training as an entry-level tec diver, taking you past the limits of recreational diving.
What You'll 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
