What should a scuba dive log include?

A useful core record includes the site, date, depth, duration, conditions, buddy, and equipment. Notes, ratings, marine life, photos, dive center details, and gas information add helpful context.

When should I fill in my dive log?

Log the dive as soon as practical after surfacing, when the site, conditions, equipment, and memorable moments are still easy to recall.

Should I use a paper or digital dive logbook?

Either can work if you use it consistently. A digital logbook adds search, sorting, maps, analytics, photos, and portable exports, while some divers also keep paper records for signatures or personal preference.

How do I keep a digital dive log from getting trapped in one app?

Export a copy on a schedule. DiveAtlas can export CSV, Subsurface XML, and UDDF as separate files so you can keep an independent archive.

How to Keep a Scuba Dive Log: A Practical Guide

1. Record the objective details first

Begin with information that is easiest to forget or confuse later. Capture the location and site, date and time, maximum depth, total duration, water temperature, visibility, entry type, buddy, dive center, and the equipment or gas details relevant to your record.

If you use a dive computer, copy the numbers from the computer rather than reconstructing them later. The logbook is a record of what happened, not a second computer.

Date, time, maximum depth, and duration
Temperature, visibility, entry type, buddy, and dive center
Equipment or gas details that you actually used

2. Add context while the dive is still fresh

A logbook becomes a memory aid when it includes more than numbers. Note the marine life you saw, navigation landmarks, conditions, photos, a rating, and a sentence about what made the dive distinctive. Short, specific notes are easier to maintain than a perfect essay.

Write the note you would want before a return trip: current, surge, a useful compass heading, or the fact that the house reef was better in the afternoon. Those details fade faster than depth and time.

3. Use the same core fields every time

Consistency makes your history searchable and comparable. Choose a small required set for every dive, then use optional advanced fields only when they matter. A quick routine after the dive is more valuable than a complicated template you postpone.

A practical default is: site, date, depth, duration, buddy, and one sentence of notes. Add gas, tank pressure, SAC or RMV, and safety flags when the dive actually used them.

4. Decide what paper still does well

Paper logbooks remain useful for instructor or dive-center signatures, for divers who prefer handwriting, and as a backup when a phone should stay dry. A digital logbook is stronger for search, maps, photos, analytics, and portable exports.

Many divers keep both for a while: paper for signatures and a digital record for the searchable history. You do not have to pick one forever on the first dive after certification.

5. Organize and back up the growing logbook

Use consistent site and buddy names, search or sort old records periodically, and export a copy in a portable format. DiveAtlas supports CSV import and export, plus separate Subsurface XML and UDDF export options, which can help you keep an independent copy of your records.

Export after a trip, not only after a device upgrade. A file you can open later is more useful than a screenshot of a stats screen.

6. Review trends without treating them as limits

Personal statistics can make a long dive history easier to understand, but they are descriptive rather than prescriptive. Your deepest or longest logged dive is a record, not a target. Follow your training, dive plan, computer, conditions, and professional guidance.

How DiveAtlas stores the same workflow

Quick Log is built for the core fields. Advanced Log adds gas, tank, pressure, SAC or RMV, and safety flags without forcing those fields on every recreational dive. The map, analytics, and memory screens stay attached to the same record, so a later search can find the dive by site, buddy, country, depth, or duration.
