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.
