WOULD U DUMP YOUR GEAR AT SEA

[MAXFACTOR]

ok folks,  I have a question. 

I was reading an article which is attached,

SITUATION.  Jan 26, 2007   AUSTRAILIA...   2 divers who did a night dive, had they're 18 ft. run about slipped its anchor and floated away.  When they surfaced they were alone and  lost at sea...at night with no one even knowing where they are.  They were found alive the next day after a search was called for.

I don't understand why they would dump all they're scuba gear except they're fins and they're wet suits.  Can someone please tell me if I'm the only one who thinks that was stupid.

ie: presumably they had air,  use of bc would be helpful, compass, a bit more protection with tank incase of shark, knife in bc if they had one....  etc etc...   
would anyone on this board dump they're gear like these guys did? 
I sure as heck wouldn't.
What do you think?
