In-water direct supervision is required for Dry and Deep, in AOW.
Indirect supervision means, "Be present and in control of the activities, but not necessarily directly
supervising all activities. Approve dive activities, oversee the planning, preparation, equipment
inspections, entries, exits and debriefings, and be prepared to quickly enter the water." Even though indirect supervision may meet the standards, that does not mean it is necessarily a good idea in terms of quality training and safety.
