CRESSI Leonardo 2.0 Scuba Dive Computer Watch — Black/Grey, Single-Button, Nitrox & Air Modes

The CRESSI Leonardo 2.0 is a single-button scuba dive computer watch that supports Air, Nitrox and Gauge modes with a large edge-to-edge screen and user-replaceable battery.

Designed in Italy and built for practical performance, the Leonardo 2.0 brings straightforward dive management to recreational and advanced recreational divers. It combines a rugged housing rated to 120 meters with audible and visual alarms, USB and infrared log export, and smartphone pairing for iOS and Android. The result is a compact, durable instrument that simplifies routine dive planning, in-water monitoring, and post-dive data review without an overwhelming learning curve.

How does the Leonardo 2.0 handle different gas mixes and dive modes?

The Leonardo 2.0 accommodates traditional air dives, enriched-air Nitrox profiles, and a Gauge mode for use with separate depth/timing systems. Switching between modes is performed through the single-button interface and is clear on the display, so you can adapt to shore dives, wreck trips, or deep freshwater sessions.

• Air mode for standard cylinder mixes with automatic computations.
• Nitrox mode accepts enriched O2 percentages for adjusted no-decompression limits.
• Gauge mode functions as a depth and time recorder without decompression calculations.
• CRESSI RGBM algorithm refines surface interval and desaturation timing.

What safety and alert features should I expect during a dive?

This computer uses a combination of visual and audible signals to call attention to critical parameters such as ascent rate, depth limits, and nitrogen loading. The alarms are designed to be noticeable in demanding conditions like low visibility or colder fall water where quick recognition matters.

• Audible beeps for ascent rate and alarm conditions.
• Clear on-screen visual warnings for ceiling and limit exceedances.
• User-configurable alarm thresholds to suit personal preferences.
• Robust casing resists impacts, scratches, and shock in rough environments.

How do I manage dive logs and connect the Leonardo 2.0 to other devices?

Data export and logging are flexible: use the on-device infrared or USB transfer options to move dive histories to desktop apps, or pair the unit with an iOS or Android device for wireless tracking and review. The simple connectivity options make post-dive analysis and record keeping straightforward.

• Pairing with iOS and Android for wireless logging and review.
• Infrared and USB ports for reliable, direct data transfer.
• Compact logs include depth profiles, dive time, and gas information.
• User-replaceable battery extends field serviceability without proprietary exchanges.

How easy is it to use the single-button interface underwater?

The Leonardo 2.0 is intentionally simplified: one button cycles modes, enters menus, and confirms settings, minimizing accidental inputs and learning time. Divers transitioning from multi-button computers often appreciate the straightforward control layout, especially when wearing gloves in colder water.

• Single-button operation reduces menu complexity for quick adjustments.
• Large edge-to-edge display improves readability at a glance.
• Logical menu flow speeds configuration before and after dives.
• Ergonomic strap and housing designed for comfort and secure wear.

Who this is for: The CRESSI Leonardo 2.0 is ideal for recreational and advanced recreational divers who want a dependable, easy-to-read dive computer that covers air and Nitrox diving without excessive complexity. Its durable construction, clear alarms, and versatile connectivity suit weekend lake explorers, coastal dive travelers, and instructors who need a reliable instrument for varied fall and year-round conditions.
