I dropped by a dive club the other day to go on a dive with my buddy, when a group of newly certified divers entered. As they started chatting, they started discussing the difference between fins and flippers.
Now that struck me as weird..cos to my knowledge, both fins and flippers are supposed to be synonymous, and I have seen experienced divers make fun of nondivers and newly certified divers when they unknowingly start looking for "flippers" instead of fins!
So my question is why do we divers call it fins...and not flippers...and is there really a difference?
Every time i hear the word flippers it reminds me of dolphins...lol..For me the word is too "dolphiny"
Its almost the same situation as when nondivers mistakingly call air tanks..."oxygen tanks"
. In this case, its obvious why the divers make fun of the beginners who make this mistake. but its not so clear cut when it comes to fins and flippers 
Any input?
