What do you need to catch a fish at a depth of 20 meters? A boat, a rod, some tackle, maybe a beer or two? Or, if you're more adventurous, a full scuba setup and a trusty spear-gun perhaps? How about trying the spear-gun without the underwater breathing apparatus. Oh, and you can't use any weights and you must stay down (for up to five minutes) until you catch your fish.
That's crazy talk, right!?!
Well, maybe not so much. I recently watched a remarkable BBC series called the Human Planet, all of which I would highly recommend. The episode on oceans was particularly interesting to my though, particularly the segment which featured a Bajau fisherman named Sulbin who was able to accomplish the feat I just described.
Unlike the (literally) breathtaking free-diving clip that John shared with you a few months back, this is the real thing from start to finish. Enjoy, and remember: dont try this at home!
