How long can we breathe underwater as beginner scuba diver?

The duration of a dive depends on many factors, which sometimes have nothing to do with being a beginner, but are related to how relaxed the diver is underwater. When the diver is relaxed the dive will last longer. It can also depend on the depth of the dive, with deeper dives, the time is shorter. After you complete the discover scuba diving course, the dive in the open water (after a pool session) is between 20 minutes up to 50 minutes depending on each scuba diver.
