WATCH: GoPro footage shows a Florida man's close encounter with a shark

They say "live every week like it's Shark Week!" That's questionable advice, but if you are going to live by that creed at least strap a GoPro to your head? A Florida man was scuba diving while his daughters relaxed on the boat, when the anchor came loose and drifted three miles away...just as the sharks began to circle.

He used his high visibility yellow backpack as a flag attached to the top of his spear gun and blew his whistle as hard as he could to try to get the attention from other boaters- all while keeping his eye on the shark.

Watch video above for full story.
