I can hardly breath while these maniacs dive into the ice hole without adequate gear, minimal training/experience, and a clueless/inattentive/unexperienced Safety Watch... then the gold is never under the ice hole (where the diver can do an emergency surface), so they have to go to the far reaches under the ice.
Also, every time their regulator freezes, I want to go slap the stupid out of everyone that says "it looks fine to me. I think you just panicked."
