Donna was just 40 and very fit and healthy, often in the gym or cycling and actively training for her next marathon. She was a qualified dive master with experience of all conditions, over 300 dives, and had spent a year in Indonesia instructing. She was cautious and professional. I believe she was PADI trained but not absolutely sure about that.
Nick, thank you for your contribitions to this Board. You are helping others to learn to avoid dive accidents. Thank you.
Donna sounds like an expereienced diver.
Donna also exercised and was in good shape. Did she have any underlying medical conditions that you are aware of? I ask, because this information might be helpful in ascertaining what happened.
Did Donna have a buddy on this dive?
