DONATELLO is the successor to the prestigious Leonardo and has been designed, developed and produced 100% in Italy by its subsidiary Cressi Elettronica. It is a completely modular construction computer, robust and with a large UFDS screen that inherits the proverbial ease of navigation and menus of computers with Cressi software. It has Nitrox management, Gauge mode, Apnea mode, reset option. The algorithm incorporates RGBM and deep stop.
Menus and navigation system identical to the rest of the Cressi dive computers, therefore, with ease of reading, access to data and modification of exemplary parameters. Remarkable ease of configuration, navigation through the different menus and access to the large amount of information that it provides in a very intuitive way, even with a single button.
"Use 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 and low consumption processor. It allows much faster data processing, greater backlighting power and alarm sound, and doubles the battery life compared to previous models. CPU ARM Cortex M3 32 bit | Frequency14MHz | Flash Memory 256Kb | 32Kb RAM.
CR2430 battery replaceable by the user without tools.
Optional interface with connection to the dive computer via Bluetooth simply supporting the computer and connection to the PC with a USB cable. Software compatible with all versions of Windows and Mac.
Gauge calibrated in salt water for maximum precision in the most common use.
