I cannot fathom that you dove 330 feet down to spear a fish. You must have nerves of steel.
Some day I will get certified. Right now, I just throw on a mask and snorkel and hold my breath. With that said, I would still like to try spearfishing sometime in Florida.
Not really nerves of steel or any such bravado. I'm best friends with a commercial diver and captain and he does all the hard stuff.
Here is a video of a 50lb gag I took in 200' or better.
