Why professional divers keep detailed journals of their dives and how to create a journal that actually helps you.
A dive journal is a document of your development, a treasure of your memories, and a tool for improving your level at the same time.
Basic data
The date, site, maximum depth, duration, water temperature, and visibility conditions.
Technical notes
Air consumption, lead used, and any problems with ear equalization or buoyancy.
What you saw
Marine creatures observed, new sites, and exceptional scenes.
You can use a special paper notebook or a digital app. What matters is regularity in recording after every dive.
The diver who records learns twice as much as the one who does not.
