Cressi Giotto dive computer review: Intuitive three-button multi-gas functionality.

To learn how to get the most out of your gear underwater, discover the [AquaExposure Training](/lms). ## Introduction

In the world of scuba diving, the dive computer is much more than just an accessory. It is a silent guardian of our safety, an tireless calculator that monitors our decompression profiles.

Too often, entry-level models force us to deal with cumbersome navigation. A single button becomes the master of a symphony of menus. Underwater, every moment is precious, and every decision must be quick and unambiguous.

Missing a setting, or worse, accidentally selecting the wrong gas mixture due to a complex procedure, can turn a pleasant diving experience into a source of anxiety. It is in this context that the Cressi Giotto comes into play.

It is presented not as a simple evolution, but as an ergonomic and technical response to the needs of divers.

We will explore together whether the integration of multiple buttons and the multi-gas management capabilities of this device justify considering it a worthwhile investment. Does it allow us to overcome the limitations of more basic models?

Overall score: 3.5/5

Algorithm & tiers (4.1/5)

The Giotto, true to Cressi's historical lineage, incorporates the RGBM algorithm. This is the result of a collaboration with Bruce Wienke.

This algorithmic model takes into account successive dive profiles. It applies a penalty to rapid ascents, thus ensuring a comfortable safety margin for the diver.

It offers a cautious and proven approach to decompression management.

To learn more:

• Algorithm: Cressi RGBM.
• Gradient Factors: No (predefined conservatism levels available).
• Display: TTS, mandatory steps.
• Alert: Rapid and graphical CNS feedback.

Air & mixed gases (2.2/5)

This computer is designed for divers who want to explore beyond basic air or Nitrox diving.

It allows you to plan a dive using a bottom gas mixture and configure a bailout cylinder for decompression stops.

It is an excellent tool for learning accelerated decompression. It offers considerable flexibility for divers who are progressing in their training.

To learn more:

• Gases: 2 gases (Gas 1: 21-50% / Gas 2: 21-99%).
• Trimix/CCR: Not present.
• Air integration: Not available.

Screen & Ergonomics (3.6/5)

Ergonomics is a major strength of the Giotto, especially when compared to models like the Donatello.

Its three-button interface allows for smooth navigation: forward, backward, and confirm.

This simplicity is crucial underwater, especially during a gas change. It significantly reduces the risk of error.

The UFDS (User-Friendly Display System) screen is large and well-organized, offering excellent readability.

To learn more:

• Display type: High-visibility LCD segments (UFDS).
• Display size: Very large (65mm case).
• Navigation: 3 physical buttons, easy to use even with neoprene gloves.

Battery Life & Power (4.2/5)

LCD segment displays are known for their low power consumption.

The Giotto offers excellent battery life. You can perform a large number of dives without worrying about running out of power.

Replacing the CR2430 battery is a piece of cake. It can be done by the user with just a simple coin. This is very convenient when traveling or on a boat.

To learn more:

• Battery type: CR2430, user-replaceable.
• Indicator: Battery level gauge.

Connectivity & App (3.0/5)

The management of data collected after a dive is an area where the Giotto shows its limitations, especially considering the initial purchase.

The computer stores the last 60 dives (or 70 hours) in its memory.

To transfer them to a digital dive log, it is necessary to acquire a Cressi transfer interface. This is an additional cost to consider.

To learn more:

• Synchronization: USB cable/Infrared or Bluetooth (via optional external module).
• App: Cressi App (user-friendly interface).

Compass & Instruments (2.5/5)

The Giotto focuses on providing essential information for diving.

It does not have a built-in electronic compass. This means that if navigation is a key element of your dives, you will need to provide a traditional analog instrument.

It offers secondary modes such as the Gauge mode (depth gauge) and a basic freediving mode. This covers essential needs.

To learn more:

• Compass: Not available.
• Dedicated modes: Air, Nitrox, Gauge, Free.

Robustness & Depth (4.3/5)

The design of the Giotto incorporates stainless steel inserts. These are not only aesthetically pleasing, but above all, functional. They effectively protect the dial from impacts.

It is certified for a maximum depth of 120 meters.

It offers a safety margin that is more than sufficient for the vast majority of dives, including those that take us to significant depths.

To learn more:

• Certified depth: 120 meters.
• Material: Reinforced case with stainless steel bezel, protected glass.

Price & Customer Service (4.1/5)

Priced between €200 and €250, the Giotto offers a very competitive price-to-performance ratio. It is a computer capable of handling oxygen pure decompression.

Cressi's after-sales service, well-established in Europe, is undoubtedly a significant advantage.

Cressi is strict about warranty terms. A malfunction caused by misuse may be less likely to be covered.

However, the presence of a good European network provides reassurance.

To learn more:

• Observed price: ~ €230 (recorded in July 2026).
• Warranty: 2 years manufacturer's warranty.

The Cressi Giotto is the ideal tool for recreational divers or those at Level 2/Advanced. It is suitable for anyone who wants to learn about multi-gas decompression with an intuitive piece of equipment.

Its ease of use and ability to manage two gases make it a perfect companion. It helps those who want to improve their practice without encountering complex interfaces.

On the other hand, it is not suitable for technical divers (using Trimix or CCR). It is also not for those who are looking for a high-resolution color screen and advanced air integration features.

It is designed for a pedagogical and safe progression in advanced recreational diving.

Cressi's after-sales service has a strong presence in Europe, particularly in Italy and Spain.

This proximity is certainly an advantage for managing warranties and repairs.

Cressi has a strict policy regarding warranty terms. Malfunctions resulting from improper use of the computer may be handled with less leniency.

Therefore, it is essential to thoroughly understand and respect the recommended usage guidelines in order to fully benefit from this resource.

The quality of the local reseller also plays a crucial role in the smoothness and efficiency of the customer support process.

The Cressi Giotto operates with a CR2430 battery, which is replaceable by the user.

This feature is a significant advantage, especially for divers who are traveling or on cruises.

The ability to change the battery yourself, without any special tools, ensures complete independence. This avoids the inconvenience of having to find a service center.

It is a precious freedom that contributes to the diver's peace of mind. It allows them to fully concentrate on their dive without fearing an unexpected power failure.

For those interested in the Cressi range, it is worth considering other models.

The Cressi Leonardo, for example, offers a simpler approach with a single button, which is ideal for beginners.

The Cressi Donatello, on the other hand, offers intermediate features.

Each of these computers caters to specific needs. It's always beneficial to compare them in order to refine your choice. Find our detailed analyses on:
