Understanding currents and tides

Article Abstract:

Scuba divers should learn the basics of currents and tides to make their progress in the water much easier. Currents usually alter their force and direction from hour to hour without any warning. Swimming against a current forces scuba divers to exert more energy and burn oxygen much faster. Scuba divers should orient themselves frequently to stay on course and make progress without exerting too much effort.

The final ascent

Article Abstract:

The greatest risk of decompression injury to a racer might transpire in the final 20 feet phase of a diving race when bubbles grow fastest and the diver runs the greatest risk of arterial gas embolism. Hal Watts, owner of Forty Fathom Grotto near Ocala, and a very experienced instructor gives safety tips to avoid such a disaster.
