I have carried on of the original roll up snorkels in the round half cover in my BC pocket for years. Signal mirror (wetnotes) too. Haven't ever used them, but they are there. The new Lifeline Nautilus is now clipped beside my snorkel. (Some of my buddies use it to call the boat at the end of their dive.) Much smaller and more convenient than a GPS and marine radio in a UK 1200 light housing. When diving in the Pacific or out so sight of land, I carry a PLB in a dive canister. Hope to never need it either. Guess I am getting off topic...
Guy I knew in California said snorkels were mandatory for beach diving in one spot, so he bungee'd it to the back of his double 104's!
