Introduction
Often, after completing their initial certification and purchasing an entry-level dive computer, divers find themselves limited when they want to begin a "Certified Nitrox" course that requires a decompression block. The Cressi Michelangelo aims to overcome this limitation. Keep in mind the fundamental principle: a dive computer is not just a timer for your dives, it's the tool that manages your decompression safety. A direct evolution of the Donatello platform, the Michelangelo retains a very robust round casing but hides a more powerful processor under its screen, and most importantly, the ability to manage a second gas. This test aims to determine if this model is a coherent and safe choice for recreational divers who are beginning to explore accelerated decompression.
The Verdict in Summary
| Overall Score: 3.3/5 | Criterion | Score | What it means |
|---|---|---|---|
| Algorithm & decompression stops | 4.1/5 | Cressi RGBM algorithm, a safe but non-adjustable Gradient Factors model. | |
| Air & multi-gas | 2.2/5 | Management of two switchable gases, but no Trimix, CCR, or air management features. | |
| Screen & ergonomics | 2.9/5 | Large and readable screen, but single-button navigation can sometimes be cumbersome. | |
| Battery life | 3.8/5 | User-replaceable CR2450 battery offering long battery life. | |
| Connectivity & app | 3.4/5 | Bluetooth connection possible via an external paid interface. | |
| Compass & instruments | 3.2/5 | No integrated electronic compass, but a complete freediving mode is available. | |
| Robustness & depth rating | 3.7/5 | Solid housing protected by a resistant metal bezel. | |
| Price & customer service | 4.2/5 | Excellent entry-level price for multi-gas functionality with reliable customer service. |
Detailed Analysis
Algorithm & decompression stops (4.1/5)
The Michelangelo is based on the Cressi RGBM algorithm, a two-phase model based on the classic Wienke RGBM. Known for penalizing inverted profiles and excessively fast ascents, it provides a safety guarantee for successive dives. The conservatism levels allow you to adapt the decompression stops to your physical condition.
Air & multi-gas (2.2/5)This is a key feature of this model: the ability to record two gas mixtures. You can dive with air at depth and switch to a richer Nitrox mix at shallower depths, and the Michelangelo will recalculate your decompression in real time. Air integration is not offered on this unit.
Screen & Ergonomics (2.9/5)
Underwater, the information is perfectly segmented and readable thanks to the large, high-contrast screen. However, switching between gases at 20 meters depth using a long press / short press on the single stainless steel button requires dexterity and practice.
Battery Life (3.8/5)
Cressi has optimized the processor to minimize battery consumption of the CR2450 battery. You should be able to get through a year of intensive diving, and replacement is quick, taking only a few minutes with a simple coin.
Connectivity & App (3.4/5)
As with the rest of this Cressi range, synchronization with your smartphone is not native. The computer has the necessary connectors, but you need to purchase a separate Bluetooth interface to download your digital dive log.
Compass & Instruments (3.2/5)
The absence of an electronic compass keeps the price low, so you will need to keep a compass on your console or wrist. However, the Free/Apnea mode is very comprehensive and appreciated by those who alternate between disciplines.
Durability & Depth Rating (3.7/5)The Michelangelo inspires confidence. Its housing incorporates a chrome-plated brass ring. This is not just for aesthetics- it provides significant protection against impacts from the blocks or the boat's ladder.
Price & Customer Service (4.2/5)
At this price, it's one of the few high-quality multi-gas dive computers that doesn't require you to mortgage your regulator. Add to that a customer service department known for its efficiency in Europe, and the investment becomes very reasonable.
Who is this computer for?
This model is aimed at a specific audience- those who value a balance between performance and affordability. It's essential to understand your needs before making an informed choice.
Customer Service & Support
Regarding customer service, Cressi has a solid reputation. Good European local support (Italy/Spain). They are strict about warranty conditions (user-caused failures = little tolerance).
Power SupplyAutonomy is a crucial factor for any diver. The Cressi Michelangelo uses a CR2450 battery, which can be easily replaced by the user. This feature is a major advantage, especially during extended cruises where access to an electrical outlet to recharge a built-in battery may be limited. The ability to change the battery yourself, without special tools, provides peace of mind and great flexibility for long trips or consecutive dives. It's always wise to have a spare battery in your equipment kit- a small precaution that can prevent many inconveniences underwater.
