Be the one ready to help a fellow diver should the need arise by becoming a PADI Emergency Oxygen Provider.
Breathe easy—knowing that you know how to recognize illnesses treatable by emergency oxygen. Being the best buddy you can be means being prepared – especially in a time of need.
Water may cover seven tenths of the Earths surface, but if it weren't for exposure suits, diving would be limited to a relatively narrow band straddling the equator. That would indeed be unfortunate as some of the best diving lies well north and south of the tropical waters and also in lakes, at altitude and at deeper depths that constantly remain cool. Without protection from the cold, some of the best diving would be inaccessible.
Of the exposure suit types available, the dry suit has opened the door to comfortable diving in the coolest waters.
