I got into diving pretty full on, spearing fish, catching Crays... pretty good fun, than I wanted to go deeper and deeper, did the swan down south, did the key Biscayne and a few other ones Gemini and a heap around 35 metre plus. retrieved stuck pots on the cray boat in swell in caves and ledges heaps of adrenaline than I nearly died (couple of times/air/overconfident/narced/big Swell)
now i just surf, don't dive so much other than a bit of free diving.
So yeah to summarise maybe get into diving, it's good fun
there is so many sub catagories
