Product Overview

The Cressi Leonardo 2.0 is a sophisticated yet accessible underwater dive computer that blends Italian craftsmanship with practical functionality, making it an ideal choice for both novice divers and experienced enthusiasts who value simplicity without compromise. Designed and manufactured in Italy by Cressi—a pioneering brand in scuba diving, snorkeling, and freediving equipment—this dive computer delivers reliable performance in a compact, travel-friendly form. Its wide UFDS display ensures crystal-clear visibility, while the intuitive single-button interface allows effortless navigation through essential dive modes. Whether you’re exploring coral reefs or diving in open water, the Leonardo 2.0 offers peace of mind through advanced algorithms, customizable settings, and robust safety features.

Key Features

• Single-Button Interface with Three Dive Modes: The Leonardo 2.0 simplifies operation with a single-button design that enables quick and intuitive switching between Air, Nitrox, and Gauge modes—even for first-time users. This streamlined approach eliminates complex menus, allowing divers to focus on their underwater experience. The interface is consistent across all Cressi dive computers, ensuring familiarity and ease of use regardless of which model you’re accustomed to. Whether adjusting settings pre-dive or reviewing data underwater, navigation remains effortless and stress-free.
• User-Friendly Display System (UFDS): Featuring an edge-to-edge, high-definition screen, the Leonardo 2.0 presents large, legible numerical displays that enhance readability in all diving conditions. The display layout is carefully engineered with optimized contrast, digit size, and proportions to ensure clarity at a glance. Information is neatly separated by light lines, minimizing visual clutter and improving comprehension during critical moments. The back-lit screen can be activated manually via button or automatically when an alarm sounds, ensuring visibility in low-light environments.
• Advanced Algorithm with RGBM and Deep Stop: At the core of the Leonardo 2.0 is a sophisticated decompression algorithm that integrates Reduced Gradient Bubble Model (RGBM) and Deep Stop technology to enhance safety and reduce the risk of decompression sickness. This system dynamically adjusts to your dive profile, offering conservative yet efficient ascent recommendations. Combined with user-selectable conservatism levels, it provides personalized safety margins tailored to individual diving styles and experience levels.
• Complete Nitrox Management and Customization: The computer supports full Nitrox compatibility with adjustable FO2 settings ranging from 21% to 50% and PO2 limits between 1.2 and 1.6 bar, allowing divers to optimize gas mixtures for maximum bottom time and safety. A real-time CNS oxygen toxicity graphic indicator continuously monitors oxygen exposure, offering visual feedback to prevent overexposure. This level of control makes the Leonardo 2.0 suitable for recreational and technical diving applications alike.
• Smart Connectivity and Data Management: With an optional BT Interface (sold separately), the Leonardo 2.0 can wirelessly connect to smartphones via infrared (IR) communication. Using the official Cressi app—available for both Android and iOS—divers can download and analyze their dive logs, track training progress, and share experiences. This digital integration enhances post-dive review and long-term performance monitoring.
