The world of SCUBA is full of abbreviations and acronyms, and it can sometimes be difficult for new divers to remember everything. Like any new sport or passion, the knowledge comes slowly with time as you gain more experience and take more courses – and of course through lots of repetition! Here’s a fairly comprehensive list of 45 to get you started. Do you know all of these? How many did you get correct and can you think of any extra’s that we have missed?…
