Cressi Leonardo 2.0 Underwater Single-Button Scuba Dive

Product Overview

The Cressi Leonardo 2.0 is a sleek, Italian-engineered dive computer that combines simplicity, reliability, and advanced functionality for divers of all experience levels. Designed for both newcomers to the sport and seasoned underwater explorers who value straightforward performance, this compact device delivers essential dive data with exceptional clarity and ease. Its modular construction ensures durability, while the expansive UFDS (User-Friendly Display System) screen presents critical information in large, high-definition digits for instant readability. Whether you’re diving on air or Nitrox, the Leonardo 2.0 offers seamless navigation and intuitive operation, making it an ideal companion for recreational diving and training alike.

Key Features

• Single-Button Interface with Three Dive Modes: The Leonardo 2.0 features a streamlined single-button control system that allows divers to effortlessly switch between Air, Nitrox, and Gauge modes—even on the first use. This intuitive design eliminates complex menus and reduces the learning curve, making it perfect for beginners while remaining efficient for experienced divers. The button also activates the back-lit display, ensuring visibility in low-light or deep-water conditions. Combined with automatic alarm-triggered illumination, this feature enhances safety and usability during every dive.
• User-Friendly Display System (UFDS): Engineered for maximum readability, the UFDS presents all dive data with carefully optimized contrast, digit size, and screen proportions. Information is logically separated by light lines, allowing divers to quickly interpret critical metrics—even in high-stress or emergency situations. The edge-to-edge high-definition screen ensures large, clear numerical displays without compromising the computer’s compact, travel-friendly form. This thoughtful layout supports fast decision-making and reduces cognitive load underwater.
• Complete Nitrox Management and Customization: The Leonardo 2.0 supports full Nitrox functionality with adjustable FO2 levels ranging from 21% to 50% and PO2 settings between 1.2 and 1.6 bar, enabling precise gas mixture planning. A built-in CNS (Central Nervous System) oxygen toxicity graphic indicator provides real-time monitoring of oxygen exposure, enhancing safety during extended or repetitive dives. These customizable parameters allow divers to tailor their experience based on depth, duration, and personal safety preferences.
• Advanced Algorithm with RGBM and Deep Stop: Utilizing a sophisticated algorithm that incorporates Reduced Gradient Bubble Model (RGBM) and Deep Stop technology, the Leonardo 2.0 optimizes decompression calculations for safer ascents. The user-selectable deep stop function adds an extra layer of conservatism, supporting improved off-gassing and reduced risk of decompression sickness. This makes the computer suitable for divers seeking enhanced safety margins during multi-level or repetitive dives.
• Smart Connectivity and Battery Efficiency: With an optional BT Interface (sold separately), the Leonardo 2.0 can wirelessly connect to smartphones via infrared communication. Using the official Cressi app (available for Android and iOS), divers can download and analyze dive logs, track training progress, and manage settings. Powered by a long-lasting CR2430 button battery, the device includes a battery saver mode that activates during inactivity and an automatic power-on feature. A clearly visible battery indicator and distinct audible alarms ensure you’re always informed of power status and critical dive events.
