The trend from 2012 continue and most accidents where under direct supervision of Instructors or Guides.
- To be fair a 20% where non trained divers and without supervision, however students during training where 60% of total, which brings into question the current programs and Instructors training capabilities, besides of individual Instructor ability and teaching experience.
- Solo diving % as usual was way less than team diving, even presumable less practiced in comparison.
- Poor gas analysis and switching techniques claim again complacency.
Conclusion : Bringing it to the point, how easy is to become a Cave Instructor versus to really understand the risk management skills, candidate preparation and mentorship need to safely introduce divers into overhead diving.
Rising the minimum requirement bar seems a predictable solution.
