Suunto D4f has a detailed logbook and dive history available in memory mode.
The logbook contains a sophisticated dive profile for each recorded dive. The time between each data point saved in the log is based on the configurable sample rate (see Sample rate).
The dive history is a summary of all recorded dives.

The logbook capacity depends on the sample rate. With the default setting (2 sec), the capacity is approximately 3.5 hours.
If the memory is full, when new dives are added, the oldest dives are deleted.
The contents of the memory remain when the battery is changed (providing that the battery has been replaced according to the instructions).
Repetitive dives on the same day are considered part of the same dive series.
Within each series, the dives are given numbers. The first dive of the series is DIVE 1, the second DIVE 2, and so on.
