Dive history

Suunto D4i 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.

To access dive history:

1. Press MODE until you see MEM.
2. Switch between History and Logbook with DOWN or UP.
3. When you are viewing the history or logbook, you can press MODE to go back and select the other one. Press MODE a second time to exit.

History

When you have entered the dive history view, you can switch between Scuba History and Free Dive History with DOWN and UP.

Scuba dive history shows you a summary of the following:

• Dive hours
• Total number of dives
• Maximum depth

The scuba dive history records a maximum of 999 dives and 999 diving hours. When these limits are reached, the counters reset to zero.

Free dive history shows the following:

• the deepest and the longest dives of all free dives
• the cumulative dive time in hours and minutes
• the total number of dives

The free dive history records a maximum of 999 dives and 99:59 diving hours. When these limits are reached, the counters are reset to zero.

Logbook

To access the logbook:

1. Press MODE three time until you come to MEM mode.
2. Press UP to choose Logbook.
3. Press DOWN or UP to scroll to the log you wish to look at and press SELECT.
4. Press SELECT to scroll through the pages.
5. Press MODE to exit.

Each log has three pages:

1. Main page

• maximum depth
• date of dive
• type of dive (indicated by first letter of dive mode, such as A for Air mode)
• dive start time
• dive number – from oldest to newest
• gas percentage(s) of the first used gas mix
• total dive time (in minutes in all modes)
• Surface time and warnings page

• maximum depth
• surface time after previous dive
• average depth
• consumed pressure (if enabled)
• warnings
• OLF% (if applicable)
• Dive profile graph

• water temperature
• tank pressure (if enabled)
• depth/time profile of the dive

Press UP to step through the dive profile graph or keep UP pressed to auto-scroll.

The dive profile graph shows point by point dive information such as depth, decompression info, ceiling and ascent time.

The End of Logs text is displayed between the oldest and most recent dive.

The logbook capacity depends on the sample rate.

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).
