Laconia Diving Mani Gytheio Monemvasia
Laconia Diving Mani Gytheio Monemvasia. Scuba diving is a mode of underwater diving where the diver uses an apparatus.This is completely independent of surface supply to breathe underwater. The name “scuba”, an acronym of “Self-Contained Underwater Breathing Apparatus“. It was first used by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas usually compressed air. It allows them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver through a diving regulator. They may include additional cylinders for range extension, decompression gas or emergency breathing gas . Closed-circuit or semi-closed circuit rebreather scuba systems allow recycling of exhaled gases.
