Scuba Diving Computer Cressi Donatello

Donatello has very complete Nitrox management with two mixes, Gauge mode, Apnea mode.

The algorithm incorporates RGBM and deep stop.

Menus and navigation system with ease of reading, access to data and modification of model parameters.

Remarkable is the ease of configuration, navigation through the different menus and access to the large amount of information that it always provides in a very intuitive way, even with a single button.

"Use a friendly display system." The information distribution, screen contrast, proportions and size of the digits have been studied to facilitate reading. All data is presented segmented with slight separation lines that facilitate reading even in stress or emergency situations. Backlit display by push button or in case of alarm.

New high-performance, low-power processor. It allows a much faster data processing, greater backlight power and alarm sounding and multiplies the battery life by two compared to previous models. 32-bit ARM Cortex M3 CPU | Frequency14 MHz | 256 Kb Flash Memory | 32 Kb of RAM.

User-replaceable CR2450 battery without tools.

Interface with connection to the dive computer via Bluetooth simply by supporting the computer and connection to the PC with a USB cable. Software compatible with all versions of Windows and with Mac.

Gauge calibrated in salt water for maximum precision in the most common use.

New menu navigation system and parameter entry for maximum usability and intuition. Remarkable is the ease of configuration, navigation through the different menus and access to the large amount of information that it always provides in a very intuitive way
