Technical Diving

Let’s start by what is the definition of technical diving?


Technical diving is defined as any diving that involves the use of ‘non standard’ sports diving kit and gas, when standard kit is classed as a single tank, with or with out a pony cylinder and with air, 32% or 36 % as a breathing gas mix.

So what does this include?

Again this has a variety of definitions in the main this is considered to be and one or combination of the following:

  • Twin set diving
  • Side mount diving
  • Diving on a rebreather
  • Wreck penetration
  • Cavern and Cave diving
  • Ice diving (there may be no clear exit point)
  • Beyond sports diving depths (35 – 40 metres depending on the agency)
  • Unusual nitrox gas – A nitrox mix that isn’t the standard 32% or 36%, 
  • Trimix mixed gas – adding a third gas like Helium into the breathing gas mix

So what can we offer as a club?

For those already trained. There are several disciplines covered by the above definitions of technical diving; For the diver who has completed the ADP – Accelerated decompression course, a twin set course, or one of the mixed gas courses, we run some deeper diving trips each year as well as regular trips to Chepstow to keep your skills up.

For those into cavern and cave diving – we have some cave divers in the club, who regularly head out on trips to challenge their need to be under ground. As well as running regular above ground caving trips!

For those who are rebreather divers we have around ten rebreather divers in the club, They are mostly on inspirations but have experience of different units. We support each other, and will have refresher dives in quarries to practice skills on a regular basis.

Ice diving is something we look into each winter – as we have our own open air pool which we keep full and we keep waiting for enough ice to be able to run a course.

For those who wish to train, we have access to instructors within the club currently who can train you some of the technical courses that BSAC have to offer, and access to regional coaches to cover those we cannot cover in house. We also have access to instructors outside of BSAC if you want to train with another agency, but wish to join the club and come along on the dives we offer. If you want more details on any of the above come down and see us on a Wednesday night.
