Outsiders might not consider diving the sporting world’s most demanding endeavour. But divers know how strenuous and grueling strong currents, cold water and other challenging conditions can be. So it’s no wonder that more of us are incorporating fitness into our dive training.
The average diver sightseeing at 30 feet in warm, calm seas can expect an average tank of air to last about an hour. But as any diver can tell you, our sport is anything but average. Deeper dives, stronger currents and chilly water can drastically reduce bottom time. New divers, a little panicky and prone to “panting” rather than easy breathing, have been known to suck a tank dry in 15 minutes.
