CRESSI Leonardo 2.0 Underwater Single-Button Dive Computer - Easy

In this review the CRESSI Leonardo 2.0 is presented as a straightforward, entry-level dive computer ideal for anyone learning to scuba or divers who want a simple wrist instrument to track dives. The single-button interface and wide, high-definition display make setup and in-water reading noticeably easier than many multi-button units, while full Nitrox management and adjustable conservatism give room for progression. For divers who value simplicity, readability, and reliable basic features, the Leonardo 2.0 delivers a focused package without unnecessary complexity.

Key Features

• Single-button interface: Makes switching between Air, Nitrox and Gauge modes quick and intuitive, reducing menu confusion for new divers.
• High-definition wide display: Large numeric readouts are easy to read underwater, improving safety and convenience during dives.
• Adjustable Nitrox settings: FO2 is adjustable between 21% and 50% with PO2 limits from 1.2 to 1.6 bar, supporting common recreational Nitrox mixes.
• Conservatism and safety aids: Three user-adjustable conservatism levels, a user-selectable deep stop and a CNS oxygen toxicity graphic help divers manage risk.
• Audible and visual alarms: Distinct alarms make it easier to notice important warnings even in noisy or busy dive conditions.
• Replaceable battery indicator: A CR2430 powers the device and a battery life indicator helps plan service and replacement to avoid surprises.

Who It's For

The Leonardo 2.0 is best for beginner to intermediate recreational divers who want a clear, no-frills computer that covers Air, Nitrox and Gauge modes. Dive students, frequent vacation divers, and those who prefer a simple single-button control will appreciate the familiar Cressi menu logic and readable screen.

Advanced technical divers who require multi-gas switching, dive logging with smartphone syncing, or more durable large-format displays should look elsewhere. Also, anyone who needs a very compact wristband may want to check sizing if they prefer a smaller profile.
