BSAC Explorer Mixed Gas Diver

What you learn
A BSAC Explorer Mixed Gas Diver is a diver who, when diving using the equipment specific to their qualification, is competent to:

  • Conduct dives with a dive buddy, within the limitations of the lesser qualified, in conditions already encountered by both during their training or previous experience
  • Conduct dives within BSAC Safe Diving guidelines
  • Dive to a maximum depth limit of 60 metres
  • Conduct such dives with a more experienced or more highly qualified diver to expand their experience of depth or other conditions, within the limits of their mixed gas certification, beyond that previously encountered. Such dives should be under the supervision of a Dive Manager who is ideally an experienced mixed gas diver
  • Conduct dives breathing a gas mixture of oxygen percentage greater than or equal to 18 % and a helium percentage of up to 35 %, for example, 18/35. This mixture contains the maximum permitted percentage of helium gas component for an Explorer Mixed Gas Diver, within the prescribed practical tolerances based on the final mixed gas percentages
  • Plan and conduct dives requiring mandatory decompression
  • Rescue another mixed gas diver from depth
  • Conduct dives where other divers, capable of providing assistance and rescue management skills, are available at the surface.
