Believe it or not you can do the PADI Discover Scuba Diving course (aka resort dive, try dive) 1-1 with an instructor, or a DM with DSD Instructor status - even if you cannot swim. I know many Pro's who find that (cough) a little surprising, but given the level of supervision being provided...
So I wonder if Ecu has done repetitive DSD's? There was a guy in Tioman doing this just last week. He probably didn't even realise, just thought he had a 'private guide'.
Other stuff mentioned is just so wrong on many levels, where to begin?
- Panicking in divers ... I'd say the biggest trigger in students is breathing with their face submerged. Most are naturally happy, but some just flip. Nothing to do with being able to swim.
- Task loading. You have a lot to think about while diving, and can only deal with so much before going nuts and killing yourself. Donning 30kg of gear and jumping in the sea and not being able to swim doesn't really help matters.
- Flipper was a dolphin. the things on your feet are called fins.
I think it's called a discovery dive. It's just for someone to feel how it is to scuba dive in a controlled environment--a gateway drug, if you will, so that the person will eventually take an open water course. When I took my course, one in our group did the discovery dive instead because she couldn't bloody make up her mind. I think it's done in just deep enough water to submerge a person. I think it's likened to a thrill ride or something.
And not to be pedant but:
http://en.wikipedia.org/wiki/Swimfin
Swimfins, swim fins, fins or flippers are worn on the foot or leg and made from finlike rubber or plastic, to aid movement through the water in water sports activities such as swimming, bodyboarding, bodysurfing, kneeboarding, riverboarding, and various types of underwater diving.
EDIT: aw, dammit; JR8's post on the discovery dive came in first.
