Why is my SAC not calculated?
For the SAC (Surface Air Consumption) calculation the following values are needed:
  • Duration
  • Start Pressure
  • End Pressure
  • Tank volume
  • Average depth

Die Calculation is as follows:
(start pressure-end pressure) * tank volume / ((average depth / 10) + 1) / minutes

Example:
Start Pressure: 200 bar
End Pressure: 50 bar
12 liter Tank
Average depth: 15 meter
Duration: 60 Minutes

(200-50) * 12 / ((15 / 10) + 1) / 60 = 12 liters per Minute

If one of the above values is missing, the SAC can not be calculated

Why is not all data imported by the UDCF import?
UDCF was invented to exchange dive data between different programs for decompression calculation purposes. Since buddies, weights, memos and other fields from logging programs are not relevant for decompression calculations, they did not get any fields in the UDCF-specification and can therefore not be imported.

Why does the import function tell me, that certain dives have been skipped?
divelogs checks if a dive already exists, based on the date and time. If you have several dives on the same date and didn't enter a time, divelogs will think that these dives are the same. You can avoid this by giving all your dives distinct date-time-combinations

Where can I get an interface for downloading dives from my dive computer?
You can always buy the original manufactureres interface, but they are usually very expensive. It is always worth looking for third party interfaces for your dive computer that are much cheaper and mostly work as good as the originals. There are also some DIY instructions for interfaces on the internet, that can easily be found using your favorite search engine.

Do my personal details get handed over to someone?
No personal data is shared with anyone else. Only your username and your dives are displayed (if your logbook is public). If we have your consent, completely anonymised temperature data is shared with science institutions to analyse the oceans temperature increases due to climate change

Why does the Surface interval seem to be wrong?
This can happen, if you are in the water between two dives. The dive computer may switch to dive mode for a moment and reset the counter for the surface interval, resulting in a shorter time than it really was.
