What is Dry Diving?

Dry diving is exactly as it sounds. A hyperbaric chamber is the perfect environment to test a diver's ability at depth, but in a safe and water-free environment.

Decompression illness DCI can result from a diver's inability to handle nitrogen narcosis.

If a diver is underwater the first time they experience narcosis, they can panic and risk DCI.

A dry dive can prepare a diver mentally for what can happen underwater.

What happens in Dry Diving?

Two dry dives are available: to a depth of 40 metres or 50 metres.

For the 40m dive:

  • The divers fill in a self-declaration medical form. Any questions ticked YES must be covered by a Dive Doctor's clearance form. (These can be done at LDC with enough notice).
  • Divers change into scrubs (provided).
  • After a briefing, divers (maximum of 10) enter the chamber accompanied by an LDC supervisor.
  • The chamber is compressed to 40m.
  • After maximum bottom time is reached, decompression begins.
  • At the end of the session there is a post-dive briefing plus time for questions and logbook stamping.

For the 50m dive:

  • The divers fill in a self-declaration medical form. Any questions ticked YES must be covered by a Dive Doctor's clearance form. (These can be done at LDC with enough notice).
  • Divers change into scrubs (provided).
  • After a briefing, divers (maximum of 6) enter the chamber accompanied by an LDC supervisor.
  • The chamber is compressed to 50m.
  • After maximum bottom time is reached, decompression begins.
  • Divers decompress on a 100% oxygen.
  • On coming out of the chamber there will be a post-dive briefing and time for questions and logbook stamping.

Please remember that like a wet dive, a dry dive does carry a risk of DCI, although an extremely minimal one as the environment is carefully controlled. Please report any abnormal symptoms immediately.
