Which items are typically recorded on smooth logs?

• A. Date; Purpose of dive; Air/Water temp; Dive site members
• B. Date; Depth; Repet group; MDV signature
• C. Depth; Water salinity; Air quality; Pilot's name
• D. Time of day; Weather; Fuel level; Vessel speed

Answer: (B)

Smooth logs are meant to capture the essential, verifiable details of a dive for training records and certification. The date pins the entry to a specific session; depth records how deep the diver went, a primary safety and training parameter; the repetition group shows where the diver stands in their training progression; and the MDV signature provides a qualified supervisor’s authentication that the entry is accurate and approved. Together, these elements create a concise, auditable record that supports qualification tracking and safety oversight. Other details like the purpose of the dive, environmental conditions, or crew presence aren’t standardized components of smooth logs because they’re less critical for certification and verification.
