Tec Diving Courses

Technical diving (sometimes referred to as Tec diving) is a form of scuba diving that exceeds the conventional scope (in terms of depth, bottom time and type of diving) of recreational diving, although the vast majority of technical divers dive for recreation and no other purpose. Technical divers require advanced training, extensive experience, specialized equipment and often breathe breathing gases other than air or standard nitrox.

Diving beyond recreational limits typically falls into two categories.

  • Recreational depths but with extended bottom time
  • Deeper depths.

Recreational depths but with extended bottom time

Think of Thistlegorm but a 2 hour dive, Rosalie Moiller for longer than 15 minutes on the wreck. Being able to look around the deck of the Carrier Oriskany, without just getting to it and then heading to the surface straight away. Closer to home; more than 30 minutes of bottom time on M2 or Aeolian Sky.
