3. Operating the Dive Computer

The Mares Smart Dive Computer features an intuitive interface with two side buttons for navigation and selection.

3.1 Dive Modes

The computer offers several operational modes:

• Air Mode: For diving with standard air.
• Nitrox Mode: For diving with oxygen-enriched air.
• Bottom Timer Mode: Measures dive time and average depth without decompression calculations.
• Freediving Mode: Optimized for apnea, with specific alarms and data display.

3.2 Pre-Dive Planning

Before each dive, utilize the pre-dive planning function to simulate dives based on your gas mix, maximum depth, and bottom time. This helps in understanding potential decompression obligations.

3.3 During the Dive

The display provides real-time information including current depth, maximum depth, dive time, no-decompression limit (NDL), ascent rate, and temperature. Alarms will activate if critical limits are approached or exceeded.

3.4 Post-Dive Review

After surfacing, the computer will display surface interval time and no-fly time. All dive data is stored in the logbook and can be reviewed on the device or downloaded to a computer.
