=== Data sampling, storage and upload ===
Data sampling rates generally range from once per second to once per 30 seconds, though there have been cases where a sampling rate as low as once in 180 seconds has been used. This rate may be user selectable. Depth resolution of the display generally ranges between 1m and 0.1m. The recording format for depth over the sampling interval could be maximum depth, depth at the sampling time, or the average depth over the interval. For a small interval these will not make a significant difference to the calculated decompression status of the diver, and are the values at the point where the computer is carried by the diver, which is usually a wrist or suspended on a console, and may vary in depth differently to the depth of the demand valve, which determines breathing gas pressure, which is the relevant pressure for decompression computation.<ref name="Azzopardi and Sayer 2010" />

Temperature resolution for data records varies between 0.1&nbsp;°C to 1&nbsp;°C. Accuracy is generally not specified, and there is often a lag of minutes as the sensor temperature changes to follow the water temperature. Temperature is measured at the pressure sensor, and is needed primarily to provide correct pressure data, so it is not a high priority for decompression monitoring to give the precise ambient temperature in real time.<ref name="Azzopardi and Sayer 2010" />

Data storage is limited by internal memory, and the amount of data generated depends on the sampling rate. Capacity may be specified in hours of run time, number of dives recorded, or both. Values of up to 100 hours were available by 2010.<ref name="Azzopardi and Sayer 2010" /> This may be influenced by sampling rate selected by the diver.

By 2010, most dive computers had the ability to upload the data to a PC or smartphone, by cable, infrared or [[Bluetooth]] wireless connection.<ref name="Azzopardi and Sayer 2010" /><ref name="Perdix manual" />
