To what depth and duration are candidates typically taken during pressure training?

The typical depth and duration used for pressure training is at 60 feet of seawater (FSW) for 10 minutes. This specific training depth is considered optimal for acclimatizing candidates to the pressure changes they will experience underwater. A duration of 10 minutes is long enough to allow trainees to experience pressure without risking excessive narcosis or other negative effects associated with prolonged exposure at deeper depths. This combination ensures that trainees are adequately prepared for potential underwater operations while maintaining a manageable level of physiological stress.

The other options represent either greater depths or longer durations that may lead to complications or exceed safe training parameters, as the purpose of pressure training is to provide a safe and controlled environment to help candidates adjust to underwater conditions.
