This seems crazy. I know almost nothing about spearfishing, but would assume that good visibility in the water is a necessity for identifying a fish and being able to propel a spear directly towards it. I’ve opened my eyes during plenty of duck dives at Ocean Beach and didn’t see much more than the nose of my board. There wasn’t anyone surfing when this guy slowly made his way into the ocean, although three people did paddle out once the spearfisherman made it past the break. I felt I should have told the surfers about the guy snorkeling around them with a really sharp projectile object, but I guess that’s just part of the fun of surfing Ocean Beach.
