Dive Computer Data Limitations

Some models store more information than others, even between manufacturers. For example, some air integrated Suunto models store pressure data constantly, every time a depth sample is taken. Others only store the beginning and ending pressure, not readings at the samples in between.

This page has been created to address some common queries and will be expanded over time.

Atomic Aquatics

Air Temperature

The Cobalt does not currently store the Air Temperature. MacDive will default to 0c/32f for this value.

Suunto

Pressure Data

Some Suunto models store pressure readings every sample, while some only store the beginning and ending pressure. The following models fall under this category:

• Cobra
• Vytec DS

You will see the beginning and ending pressure, but you will not see the per-sample SAC/Air graphs.

But Suunto Dive Manager shows the air pressure!

SDM simply interpolates this data based on the start/end pressure - it is not real or accurate. MacDive chooses not to do this, so you won't see it.
