Dangerous water - could be...... i wouldnt go much further unless you want accusations of advocating overhead (or other diving) without training.jviehe:Ive found that in a lot of these safer caverns, that are big and high flow, the most important thing is not to panic. You cant surface but you could swim out if you keep your head. Beyond that, staying within your limits will keep you safe. ANything more challenging than that requires special techniques and gear. Im treading in dangerous water here becuase Im making it sound easy, but I beleive people can figure out things for themselves. But, for those who cant, get trained.
Cavern training is useful for overcoming psychological problems and dealing with multi-tasking, not to mention making you aware of your buoyancy, trim and kicking - its not a course just for those who want to dive springs. It isnt impossible, but it isnt a cake walk either.
