How long can a hard hat diver stay below sea level?

Decompression time is required with both systems, but – unlike the swimming diver, who will eventually exhaust the gas tanks he or she carries – the hard hat diver can stay below indefinitely, depending on depth and time constraints.

What is the maximum depth for scuba diving?

Recreational Scuba Diving has a maximum depth of 30m / 140ft. However new divers are not trained to this depth initially. Most agencies have what we call a “Level 1 diver course”, normally described as “Open Water Diver”, this will have a maximum depth limit of 60ft / 18m.
