TECHNICAL DIVING Technical Guidelines

What is technical diving?

Technical scuba diving is defined as diving other than conventional commercial or research diving that takes divers beyond recreational scuba diving limits. It is further defined as and includes one or more of the following:

  • diving beyond 40 metres/130 feet deep
  • 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

 

Because in technical diving the surface is effectively inaccessible in an emergency, tec divers use extensive methodologies and technologies and training to manage the added risks. Even with these, however, tec diving admittedly has more risk, potential hazard and shorter vital error chains than does recreational scuba diving.

In Water Skills to be proficient in:

  • Buoyancy, Trim, and General Comfort – These need to be instinctive such that divers do not need to think about them.

  • Awareness of Surroundings – This is critical in technical diving as we need to rely on our team more than in recreational diving.

  • Position in the Water  – When on deco, students need to be able to hold their position in the water so that they can see their teammates. They should not have to swim around to keep their position. Divers need to be very comfortable in the water.

Technical diver mentality:

The most important thing a diver can do to prepare for a technical diving class is to prepare their mind.

  •  Open Your MindCome to class prepared to learn and ask questions. Instructors do not like it when students don’t ask the “Why” type questions. Limit the “internet” learning you do, unless it comes from your instructor.

  •  Stay Awake A good technical diving class will consist of long days. Stay awake during lectures and certainly don’t fall asleep underwater. Drink plenty of water and eat healthy.

  •  Be Prepared to Hear NoMany times people have bad days and may not meet the performance requirements for the course. Technical diving students need to realize that they may need more time to truly master technical diving skills before getting their certification cards.
