Dive log

The log may either be in a book, locally hosted software, or web based.

The log serves purposes both related to safety and personal records.

Information in a log may contain the date, time and location, the profile of the dive, equipment used, air usage, above and below water conditions, including temperature, current, wind and waves, general comments, and verification by the buddy, instructor or supervisor.
