The Cressi Raffaello dives into advanced planning with RGBM algorithm, built-in digital compass, and long battery life. It provides essential dive data, surface time, and desaturation times to help divers manage multi-gas scenarios. Safety features include oxygen toxicity indicators and ascent speed alarms for safer underwater exploration.
Cressi Donatello Wrist Dive Computer
The Donatello emphasizes a compact design with a single-button interface for quick mode changes and a high-definition display for underwater readability. It features a user-adjustable conservatism setting and clear audible alarms. Its versatile functionality supports imperial or metric units, deep stop options, and varied gas mixes to suit user preferences.
Cressi Leonardo 2.0 Dive Computer
The Leonardo 2.0 offers an HD backlit display, nitrox and gauge modes, and a diver-friendly interface with a single-button operation. Programmable FO2 from 21% to 50% and PO2 from 1.2 to 1.6 bar enable personalized gas management. The device includes audible alarms and adjustable conservatism to fit various risk tolerances and dive profiles.
Buying Guide: Key Purchase Considerations
- Display readability: Look for high-contrast, backlit screens with large numerals and clear dive data to reduce strain during dives.
- Gas options: Ensure the model supports Nitrox or Trimix as needed, with programmable oxygen mixes in a practical range (commonly 21%–50%).
- Decompression model: Common choices include Buhlmann ZH-L16C and RGBM. The chosen algorithm affects decompression calculations and dive safety.
- Modes and alarms: Verify available modes (air, nitrox, gauge, free), as well as audible and visual alarms for ascent, depth, and no-deco limits.
- Navigation features: Built-in compasses or easy integration for planning and orientation can enhance safety on complex dives.
- Battery life and durability: Long-lasting batteries and rugged, water-resistant design reduce maintenance and downtime.
- Interface and usability: A simple, intuitive control scheme—especially a single-button operation—helps divers adjust settings quickly underwater.
- Data accessibility: Look for clear data display of depth, dive time, descent/ascent rates, and desaturation times to assess post-dive requirements.
- Upgrade path: Some models offer firmware updates or additional features over time; consider future-proofing your purchase.
- Size and fit: Wrist size, strap comfort, and legibility under different lighting conditions influence long-term comfort during dives.
