The Dive Logbook – Why It’s Important and What to Record

A dive logbook is more than just a collection of memories – it’s an essential part of your dive training and progress as a diver. Many divers, especially beginners, often ask: Why should I keep a logbook and what should I record in it?

Why a Dive Logbook Is Important

Your logbook documents all your dives, shows your experience, and helps when taking advanced courses or doing special dives. Some courses, such as Rescue Diver (min. 9 dives), Divemaster (min. 40 dives to start DM training), Instructor (min. 100 dives), or Solo Diver (min. 100 dives), require a minimum number of logged dives. A logbook may also be required when renting dive equipment.

What Should Be Recorded in a Dive Logbook?

Date and Location: When and where did the dive take place?
Dive Site: On our boat, you’ll always find the day’s dive sites listed on the blackboard at the coffee station.
Depth and Duration: How deep did you dive and for how long?
Air Consumption: Start and end pressure of your tank. (How to calculate air consumption?)
Buddy and Instructor: Who did you dive with?
Highlights: Marine life seen, currents, wrecks, etc.
Stamp and Signature: Especially important for training dives.

Digital Logbook vs. Classic Logbook

Today, many divers keep digital logbooks using apps like Divelog, SSI, or PADI. Modern dive computers often have Bluetooth features that automatically transfer your dives to your smartphone, making digital logging almost effortless. Even older dive computers can store up to 999 dives. Still, many divers love their classic logbooks as a personal keepsake.

Who Fills Out the Logbook?

During courses, your instructors and divemasters help you fill out and stamp your logbook. For fun dives, you’re responsible for your own logbook, but our team is always ready to assist.

Fun divers who still keep a classic logbook can find the dive site names and the stamp at the coffee station on our boat. Once everything is filled out, they can get their guide’s signature. During courses, instructors explain and assist with completing the logbook.
