Cressi Leonardo Underwater Single Button Diving Computer Review
An elegant expression of simple, functional design, the Leonardo 2.0 is a must-have for divers entering the sport and for those who "just want to dive".
The Leonardo 2.0 is a completely modular, rugged computer with a wide UFDS display, which provides the proverbial ease of navigation and Cressi computer menus.
It has complete Nitrox management, depth gauge mode, and a reset option. The algorithm incorporates RGBM and Deep Stop.
Menus and navigation system are identical to the rest of the Cressi diving computers, with ease of reading, access to information, and model parameter modification.
A single-button interface makes it effortless to set Air, Nitrox, and Gauge modes the first time a diver picks the computer up, and an edge-to-edge, high-definition screen gives large numerical displays in a computer that is still compact and travel-friendly.
Easy configuration, navigation through the various menus, and access to a large amount of information displayed intuitively.
Features a “User-Friendly Display System”: the information display, screen contrast, proportions, and digit size have been carefully chosen for ease of use.
All the information presented is separated by light lines to facilitate reading even in stressful or emergency situations. The back-lit display can be activated by a button or when the alarm sounds.
Extended battery life through a combination of systems: battery saver mode when the computer is not used with automatic power-on. The clearly visible battery life indicator and distinct audible alarms deliver critical information as well as peace of mind during the dive.
Gauge calibrated in salt water for maximum precision during typical use.
The dive computer can be linked to a smartphone using the BT Interface (sold separately). It communicates with the dive computer via an IR connection. Use the Cressi app (available for Android and iOS) to download diving sessions and monitor training.
The device is powered by a long-lasting CR2430 button battery which can be replaced by an authorized Cressi center by verifying perfect watertightness.
The Leonardo can also be fully reset after each use, making it possible to give it to another diver.
The Leonardo 2.0 is developed and made in Italy by Cressi, a brand pioneer in scuba diving, snorkeling, and freediving equipment. The product is covered by a 2-year limited warranty.

The Cressi Leonardo Underwater Single Button Diving Computer stands out for its simplicity and functionality.
