What is the purpose of a dive log?

The purpose of a dive log is to document dive profiles and incidents for safety. Keeping an accurate and detailed record of each dive is essential for divers, particularly in professional settings where safety is a priority. A dive log typically includes information such as the dive site, depth, duration, conditions, and any incidents that may have occurred. This comprehensive documentation enables divers to review their performance and experiences, identify patterns, and gather valuable data that supports safe diving practices.

Moreover, having a well-maintained log can be crucial during dive planning and post-dive analysis. It serves as a historical record that can inform future dives and help in recognizing conditions, like fatigue or recurring issues with gear, that might affect divers' safety. The data within the log also assists dive supervisors in making informed decisions regarding dive operations and risk management.
