What is Technical Diving?
Technical scuba diving involves going beyond recreational scuba diving limits and includes one or more of the following:
- Diving beyond 40 metres/130 feet
- Required stage decompression
- Diving in an overhead environment beyond 40 linear metres/130 linear feet of the surface
- Accelerated decompression and/or the use of variable gas mixtures during the dive
- Use of extensive equipment and technologies
In technical diving the surface is often inaccessible in an emergency, so tec divers use extensive procedures, equipment and training to manage the added risks and potential hazards.
Why would I want to be a TEC diver?
Many spectacular, untouched wrecks lie at depths well below 40 metres/130 feet. Deep reefs have organisms you don’t find in the shallows. Some people enjoy the challenge and focus tec diving requires. Still others love being involved with cutting edge technologies. These reasons make tec diving rewarding.
However, you can be an accomplished, avid top-notch diver your entire life without making a tec dive. Tec diving does require significantly more effort, discipline and equipment, which means it’s not for everyone.
What you will learn:
You’ll learn about the advantages of diving with a sidemount configuration and how to set up a tec sidemount harness. You’ll get hands-on training during one confined water session and four open water dives where you’ll start with two tanks and add at least two more.
- Gas matching procedures to include dissimilar volumes
- Gas management utilizing independent cylinders
- Psychological considerations of technical diving
- Equipment considerations including:
- Cylinder options
- Regulator options
- Buoyancy compensator/harness options
- Proper weighting
- Equipment configurations
- Communication (light and hand signals)
- Problem solving in a sidemount configuration
- Diving in tight or confined spaces
- Water entries/exits
- S-drills specific to sidemount diving
Skills and Scenarios:
- Demonstrate various propulsion techniques such as the frog kick, modified frog kick, modified flutter kick, backwards kick, helicopter turns, and hand pulling if appropriate for the environment.
- Demonstrate adequate buoyancy control; ability to hover at a fixed position in water column without moving hands or feet
- Demonstrate adequate trim; ability to maintain proper position during the descent, bottom, and ascent portion of the dive
- Demonstrate the ability to perform the following exercises while maintaining trim and buoyancy in the water column:
- Unclipping and attaching sidemount cylinders
- Perform gas switches with and without a mask
- Demonstrate the ability to safely manage gas in independent cylinders
- Demonstrate conservation, awareness, and back referencing techniques
- Deploy a lift bag
