Product Overview
The Cressi Leonardo 2.0 is a streamlined, single-button dive computer designed for divers who value simplicity, reliability, and Italian engineering. Ideal for beginners and recreational divers who “just want to dive,” it combines essential functionality with intuitive operation. Built with a rugged, modular design, it features a high-visibility UFDS display and supports three core dive modes—Air, Nitrox, and Gauge—making it versatile for various underwater activities. Developed and manufactured in Italy by Cressi, a pioneer in diving equipment, the Leonardo 2.0 delivers trusted performance backed by a 2-year limited warranty.
Key Features
- Single-Button Interface: Effortlessly switch between Air, Nitrox, and Gauge modes with one button, allowing quick setup even for first-time users. The intuitive menu system matches other Cressi dive computers, ensuring consistency and ease of navigation.
- Wide UFDS High-Definition Display: Features an edge-to-edge screen with large, clearly separated numerical readouts. Light lines divide information sections, enhancing readability in low visibility or high-stress situations. The backlit display activates manually or automatically when alarms sound.
- Complete Nitrox Management: Customize your dive with adjustable FO2 (21%–50%) and PO2 (1.2–1.6 bar) settings. A real-time CNS oxygen toxicity graphic indicator helps monitor exposure, supporting safer Nitrox diving.
- Advanced Algorithm with RGBM and Deep Stop: Incorporates a proven decompression algorithm that includes Reduced Gradient Bubble Model (RGBM) and optional deep stop functionality for enhanced safety during ascent.
- User-Friendly Display System (UFDS): Optimized for clarity, with carefully calibrated contrast, digit size, and screen proportions. Information is logically organized to reduce cognitive load underwater.
- Smartphone Connectivity (Optional): Pair with the Cressi app (iOS and Android) via the separately sold BT Interface and IR connection to download dive logs, track training progress, and analyze sessions.
- Long-Lasting CR2430 Battery: Powered by a durable button cell battery with extended life. A visible battery indicator provides timely warnings, and authorized Cressi centers can replace it while verifying watertight integrity.
- Resettable Design: Fully resettable after each use, allowing the computer to be safely passed between divers—ideal for rental operations or shared gear.

Benefits & Use Cases
The Leonardo 2.0 is ideal for recreational divers seeking a dependable, no-frills computer that prioritizes clarity and ease of use. Its single-button operation makes it especially suitable for beginners or divers who prefer minimal menu complexity. The ability to customize Nitrox settings and monitor oxygen toxicity supports safer enriched air diving, while the deep stop and RGBM algorithm add an extra layer of decompression safety. Divers traveling frequently will appreciate the compact, travel-friendly form factor and saltwater calibration, ensuring accuracy in ocean environments. The optional smartphone integration allows for post-dive analysis and training tracking, making it a solid choice for those looking to improve their skills over time. Rental centers and dive instructors can also benefit from the reset function, enabling secure reuse across multiple divers.
Important Notes
Battery replacement must be performed by an authorized Cressi service center to maintain watertight integrity and warranty coverage. The BT Interface required for smartphone connectivity is sold separately and not included with the dive computer. Always ensure the device is properly reset and configured before each dive, especially when used by multiple divers. While the computer is designed for ease of use, users should complete appropriate training before diving with Nitrox or using advanced features. The product is calibrated for saltwater use; accuracy in freshwater may vary slightly.
