An elegant expression of simple, functional design, the Leonardo is a must-have for divers entering the sport and for those who "just want to dive".

Leonardo is the first computer designed, developed, and produced 100% in Italy by our owned subsidiary, Cressi Elettronica.

It 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 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 program 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 of 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 the 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. Power-saving processor and CR2430 battery is replaceable by the user without tools. The clearly visible battery life indicator and distinct audible alarms deliver critical information and peace of mind during the dive.

Gauge calibrated in salt water for maximum precision during typical use. The Leonardo can also be fully reset after each use, making it an excellent choice for rental departments.

• Anti-impact technopolymer case. This composition allows a great lightness, resistance to the blows, and to the aesthetic aging. The computer case is extremely flat, with a very hydrodynamic cornerless section and its dimensions are relatively contained, with a vision of the model digits.
• Extra-flat profile (maximum height 14 mm) with a completely rounded design, very hydrodynamic and avoids possible snagging. Even the anchorage of the strap follows the profile of the box.
• Two highly integrated low-profile pushbuttons with a minimised backlash to ensure that the O-rings are watertight when working perfectly perpendicularly and to prevent the entry of particles or small grains of sand that could block them.
• Case diameter only 48 mm.
• Large screen UFDS (User-Friendly Display System) 38 mm in diameter vs 48 mm total box. The distribution of the information, screen contrast, proportions, and size of the digits have been studied to facilitate the reading. All data are segmented with slight separation lines that facilitate reading even in a stressful or emergency situation.

Cressi Elettronica has developed our newest computer, the Goa, from scratch. It features a new CPU that is faster with greater functionality. Our latest motherboard is completely redesigned, allowing for a larger battery for long-lasting life. The case has a diameter of only 48 mm | 1 7/8 in and a high contrast display of 35 mm | 1 3/8 in. The computer monitor is made of mineral glass and the case is heavy duty with steel buttons that have an underwater resistance up to 120 m | 393 ft. Plastic/Steel bezel and stainless steel back cover. It has only 2 buttons making the menu easy to navigate. It not only features programs for scuba diving, but also has a program for free diving, in which it is possible to customize different alarms. It is also an ideal watch for other underwater activities due to the deactivation option of the dive functions that avoid unnecessary alarms while snorkeling or swimming. Data is acquired 4 times faster: every 5 seconds while scuba diving and every 2 seconds while free diving. Additionally, the computer acquires temperature data. The result is a more complete and precise chart that is viewable in the interface software. Through the Cressi Interface application (sold apart), a user can download and analyze the diving data recorded on the Goa. The connection between the Goa and PC (or MAC) is done using the Docking Station connected via USB cable. The Interface software allows the user to view charts and data of scuba diving and freediving sessions. It is possible to save a logbook with a memory of 50 dives per category. The records are completed with two graphs, showing the water pressure data (taken every 5 seconds) and water temperature data (taken every 5 seconds). All the information can be uploaded to the DAN (Divers Alert Network).
