Apnea Dives
Diving Log shows the dive time for scuba dives in full minutes. When a dive is shorter than 5 minutes, Diving Log will automatically switch to minutes:seconds (mm:ss), which is better for apnea (free) dives. The dive profile will show the x-axis in seconds instead of minutes. You can enter dives shorter than 5 minutes in mm:ss format or as decimal value (e.g. 0.5 = 30 seconds).
If you want to display the dive time in mm:ss in the print reports, you can use this formula:
Date$(DateHMS(0,0,LogDivetime*60),"%02i:%02s")+" min"
