These key features make the Cressi Leonardo a powerful and versatile dive computer suitable for a wide range of diving activities.

Dive Modes and Settings

The Cressi Leonardo dive computer offers three distinct dive modes to cater to various diving styles and preferences. These modes allow you to tailor the computer’s functionality to your specific needs, ensuring an optimized and safe diving experience.

• Air Mode⁚ This mode is designed for standard air dives, providing essential dive data such as depth, time, ascent rate, and decompression status. It’s the most common mode for recreational divers using compressed air.
• Nitrox Mode⁚ This mode is specifically for dives using oxygen-enriched air mixtures (Nitrox). It allows you to input the oxygen percentage (FO2) of your Nitrox mix, enabling the computer to accurately calculate decompression times and partial oxygen pressure (PO2) during your dive. This mode is ideal for divers who want to extend their bottom times or explore deeper depths.
• Gauge Mode⁚ This mode provides basic depth and dive time readings, making it suitable for freediving, shallow dives, or situations where you only require a simple depth gauge. It doesn’t offer decompression calculations or other advanced features.

Beyond its dive modes, the Leonardo also provides customizable settings to personalize your diving experience. You can adjust parameters like⁚

• Units of Measurement⁚ Choose between metric (meters and Celsius) or imperial (feet and Fahrenheit) units for depth, temperature, and other measurements.
• Dive Time⁚ Set your desired dive time and receive an alert when you reach that limit.
• Ascent Rate⁚ Configure your preferred ascent rate and receive an alarm if you exceed it. This helps ensure safe decompression.
• Sound and Vibration Alarms⁚ Adjust the intensity and type of alarms (sound and/or vibration) for various events, such as reaching your dive time limit or exceeding your ascent rate.

By customizing these settings, you can optimize the Leonardo’s functionality and ensure it aligns perfectly with your individual diving habits and preferences.
