...Non-divers are always the first to make unsupported statements on what a shark is going to do and how diver response is useless....Several divers have put shafts into large great whites and survived. A South African diver shot a 10' attacking gw in the head and killed it...A few weeks ago, a gw bit a Hawaiian diver across the torso. He repeatedly stabbed the fish with his knife, driving it away. Despite a serious injury, he survived. and..., thick kelp can be your best friend!...
... I speared a 9' Blue at point blank range that attacked me off Santa Cruz island and eventually won the battle. The spearshaft didn't even clear the gun; it was so close...My point: Be prepared to fight and you can survive. I carry a large gun and 2 knives: one on each side. If I am hit, I may be able to reach one or the other...
...Sadly, the Mexican diver above was one of 3 killed in that bay over the past 3 years.
