Missing from my basic open water:
- WHERE to go diving that is appropriate to a 'beginning diver'
- How to tell if you are renting junk.
- How to tell if the dive shop people are actually experienced divers.
- How to tell if the boat captain is inept/unqualified/drunk before you put your gear on the boat.
- How to tell if the boat is appropriate for a 'new' diver
- What is the difference between a 'six pack' boat and larger boats. (Captain requirements, equipment, inspections etc. It seems to me a 'beginning diver' will be better off on a larger boat if that boat has a good crew and not too many 'beginning divers'.)
- How much to tip / whom to tip
- How to find a dive buddy that is appropriate to your ability / desires / goals
- What 'emergency equipment' you should have for what situation (dye marker, inflatable marker, first aid kit)
Missing from every course after that; sign language !
At a minimum I think no one should be allowed to do any course beyond basic open water until after they can PROPERLY finger spell in English. I can't believe some of the disco dancing I see underwater and then on the surface the 'buddy' says "how come you didn't understand I wanted you to grab that moray eel for a picture?"
