Key Features
- Single-Button Interface: Effortlessly switch between Air, Nitrox, and Gauge modes with one button—no complex menus or multiple controls. This intuitive design ensures quick setup and easy operation, even for first-time users.
- Wide UFDS Display with High-Definition Clarity: The edge-to-edge screen delivers large, easy-to-read numerical values in a compact form. The display uses a “User-Friendly Display System” (UFDS) that separates information with light lines, enhancing readability in low visibility or high-stress situations.
- Complete Nitrox Compatibility: Customize your dive with adjustable FO2 levels from 21% to 50% and PO2 settings ranging from 1.2 to 1.6 bar. A visual CNS oxygen toxicity indicator helps monitor exposure, supporting safer extended or repetitive dives.
- Advanced Dive Algorithm with RGBM and Deep Stop: The integrated algorithm incorporates Reduced Gradient Bubble Model (RGBM) calculations and optional Deep Stop functionality, offering enhanced safety for divers seeking conservative decompression profiles.
- Backlit Display with Smart Activation: The screen illuminates automatically when alarms sound or can be manually activated via the button, ensuring visibility in dark or deep-water environments.
- Extended Battery Life and Monitoring: Powered by a long-lasting CR2430 button battery, the Leonardo 2.0 includes a battery saver mode that activates when not in use and powers on automatically when submerged. A clearly visible battery indicator and distinct audible alarms keep divers informed.
- Smartphone Connectivity via BT Interface (sold separately): Pair the computer with the Cressi app (iOS and Android) using an optional infrared (IR) BT Interface to download and review dive logs, track training progress, and analyze performance over time.
- Saltwater-Calibrated Gauge Mode: Engineered for accuracy in real-world conditions, the depth gauge is calibrated specifically for saltwater use, ensuring precise depth readings during typical ocean dives.

The inclusion of audible alarms and visual alerts ensures critical information—such as depth limits, ascent rates, and oxygen exposure—is never missed, promoting safer dive practices. Whether used standalone or paired with the Cressi app for post-dive analysis, the Leonardo 2.0 delivers a balanced mix of functionality, safety, and ease of use.
Important Notes
The CR2430 battery should only be replaced by an authorized Cressi service center to maintain watertight integrity and ensure proper function. The optional BT Interface for smartphone connectivity is sold separately and connects via infrared. While the computer supports data download and training tracking through the Cressi app, the app requires a compatible smartphone and the IR interface accessory. The 2-year limited warranty covers manufacturing defects and is valid when purchased from an authorized dealer. Always perform pre-dive checks and follow standard safety procedures when using any dive computer.
