How much gas is in a scuba tank?

Can you breathe 100 oxygen?

How deep can you dive with air?

There are depth limitations too, as nitrogen becomes narcotic the deeper you go. This becomes increasingly debilitating, so the maximum depth for recreational diving is 130 feet (40 m). Air itself becomes toxic as we go beyond 184 feet (56 m). Best used for: All recreational diving down to 130 feet (40 m).

How deep can you dive on air?

A recreational diving limit of 130 feet can be traced back decades. The deepest your typical recreational scuba diver can go is 130 feet.
