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:
• How to select and use two deco gasses to increase diver safety
• Review of the basics of decompression theory
• Explanation of common decompression models and the differences between them
• Review of the benefits of using enriched air or oxygen as a decompression gas

• Anticipating and managing common problems in decompression diving
• Review of different equipment configurations using multiple stage bottles
Skills and Scenarios:
• Recalculation of decompression requirements due to lost deco gas
• Gas switching using team protocols
• Lift bag deployment
• Using a safety lift bag for surface assistance
• Dealing with a convulsing diver at depth
• Refinement of configurations
• Narcosis test at depth
• Emergency scenarios simulations including, but not limited to: exceeded bottom times, gas sharing during a no-mask ascent,free-flowing regulators, loss of deco gas, and switching to a back-up wing or buoyancy device.
