Hazards in Wreck Diving

Shipwrecks lure divers as much as they attract the sea life surrounding them. The spectacle of life on a wreck, an ecosystem unto itself, is often the main attraction for divers. Nearly every ocean, sea and lake holds a world of shipwreck exploration for advanced open-water divers. Each lost ship, submarine, airplane and even the odd locomotive is a time capsule waiting for an underwater explorer to visit and photograph. Never venture inside a shipwreck until you have advanced wreck-dive training from a certified, qualified dive training professional.

Swimming through a wreck with good trim, buoyancy and finning technique is essential.

Saturation Diving

What is saturation diving? When the diver breathes in inert gas, it dissolves into the body’s tissues and reaches equilibrium with the ambient pressure at the diver’s depth.

A diving bell can be locked out from a saturation chamber and lowered to the seafloor. A moon pool on the underside allows divers to exit and enter the diving bell.

As an added benefit, beach diving can be quite economical compared with boat diving. And some of the most incredible sites in the world are most easily dived from the beach
