Every dive is unique—and if you want to remember the details months later and keep track of your underwater adventures, keeping a logbook is the way to go.

We’ve got a few ideas for how you can make your dive log as personal and memorable as the dives themselves.

Most training agencies and a wide range of apps offer digital logbook options where you can document your dives online.

But you can also go the old-school route and keep things analog. Grab a nice notebook and jot down your thoughts—either right after each dive or at the end of your dive day.

Make sure to always write down the name of the dive site—everything else is totally up to you. Personally, I get really emotional after wreck dives, so I like to write those thoughts down right away (shows book).

You can also note the fish or coral you spotted along the way.

And if you’re ever unsure about what species of fish you saw—like which kind of bream it was—just check out DiveDict.com to find everything you need.
