How long does a tank of air last?
This is a common question that, unfortunately, doesn’t have a single answer. People breathe at different rates, and you breathe faster when you’re swimming than when you’re resting. Also, the deeper you go, the faster you use your air, and, you can get different size tanks. So, the answer is “it depends;” this is why divers have a gauge that tell them how much air they have at all times. As an approximation, though, a diver sightseeing in calm, warm water in the 5 meter / 15 foot to 10 meter / 30 foot range can expect the average tank to last about an hour.
This is a common question that, unfortunately, doesn’t have a simple answer. People breathe at different rates. You breathe faster when you’re diving than when you’re resting. Also, the deeper you dive, the faster you use your air. Men tend to use more air then women. The more relaxed you are under the water, the less air you use so experienced divers use less air. So, the answer is “it depends”. This is why divers have a gauge that tell them how much air they have at all times.
Since people breathe at different rates and as you go deeper you consume air faster, there isn’t any one answer. Because of this, divers carry a gauge that lets them know how much air is in the tank. However, divers in calm, warm water from 5-10 metres/15-30 feet can spend about one hour underwater with an average tank.
