The Cressi Raffaello dive computer is designed to meet the needs of both recreational and more demanding divers, including those using mixed gases or practising freediving. It combines intuitive operation with technical flexibility in a robust, low-profile wrist format.

It offers four dive modes—Air, Nitrox, Gauge and Free/Apnea—with Nitrox dives allowing up to three gas mixes and PPO₂ adjustable between 1.2 and 1.6. The built-in RGBM decompression algorithm provides dynamic ascent profiles, while alarms alert to unsafe ascent rates, PPO₂ exceedances and safety-stop requirements. A graphic indicator displays oxygen toxicity levels for CNS monitoring 

The display is large and high-contrast, backlit for visibility in low light, showing essential data such as depth, dive time, surface and desaturation status, and no-fly time. A digital compass supports directional navigation, with fixed heading or drift tracking available 

A silicone wrist strap adapts comfortably even over a drysuit, while two robust metal buttons permit menu access under all conditions. The housing is durable, scratch-resistant, and features mineral borosilicate glass. Powered by a long-life, user-replaceable battery estimated to last four years and easily swapped without specialist tools. 

The logbook records up to 50 dives per mode, and data transfer to PC or mobile via Bluetooth or USB is optional. This computer is designed for divers seeking a reliable, multi-mode wrist instrument—balancing technical capability with straightforward usability, and focusing on functional features rather than aesthetic enhancements.
