Cressi Digi 2 Console Review: Digital Instrumentation to Replace Analog

To learn how to get the most out of your gear underwater, discover the AquaExposure training.

In the cold and often murky waters of a Belgian quarry, equipment clutter quickly becomes a major logistical challenge. When your hands are monopolized by a heavy waterproof housing for a Sony RX10V or by an Insta360 X5 pole, you cannot afford to squint at a faded old analog pressure gauge. Checking your pressure must be done at a glance to immediately return your attention to your buddy and your environment. The Cressi Digi 2 responds precisely to this need for efficiency.

Let's clear up a fundamental ambiguity from the start: the Digi 2 is not a decompression computer. It is a miniature electronic console of very high precision that screws directly onto the high-pressure (HP) hose to permanently replace your mechanical pressure gauge and analog depth gauge. By digitizing these vital parameters, it brings brand new features like the calculation of remaining air autonomy in minutes. Let's apply our evaluation grid to this singular instrument.

Global Score: 2.9/5 (Score artificially impacted by the lack of decompression calculation)

This instrument is made for: The diver or photographer who already has a watch-format decompression computer on their wrist, and wants to replace their heavy analog console with an ultra-readable digital display with autonomy calculation.

This instrument is not ideal for: Anyone looking for a complete primary computer to manage their safety stops.

O1 Algorithm & stops (1.0/5)

The Digi 2 is out of category on this point, as it does not possess a Bühlmann or RGBM algorithm. It is a measuring instrument (Gauge).

Display: It logs your current depth (with one decimal place), your dive time, and the maximum depth reached during the current immersion. (Score: 1/5)

O2 Air & multi-gas (1.5/5)

This is where the device reveals its full potential by automating the reserve management.

Pressure reading: Cylinder pressure is displayed in large digits with a precision of 0.1 bar (up to 300 bars maximum pressure). (Score: 2/5)

Remaining autonomy: The software continuously calculates your breathing rate and displays the minutes of autonomy left at your current depth. The device also features a very clear flashing visual indicator when the pressure drops below 50 bars. (Score: 2/5)

O3 Screen & ergonomics (3.5/5)

The miniaturization performed by Cressi is spectacular, freeing the equipment of any visual or physical overload.

Format and Readability: The rectangular 45 x 27 mm screen is luminescent and allows each piece of information to be separated by clear lines to avoid any confusion. The unit is remarkably light (only 122 grams compared to double or triple that for analog brass). (Score: 3.5/5)

Navigation: The device is devoid of buttons, which eliminates risk of infiltration and sediment accumulation. Activation is fully automatic when opening the cylinder (hose pressurized). (Score: 4/5)

O4 Battery & power (4.8/5)

The console's energy management system is particularly innovative and reassuring.

Battery type: CR2450 button cell. It offers a massive autonomy of up to 1000 hours in immersion. (Score: 4.5/5)

Cressi Patent: During battery replacement by the user, the computer performs a self-diagnostic (patented by the brand) to verify that the chamber is perfectly sealed before returning to the water. (Score: 5/5)

O5 Connectivity & app (1.0/5)

The Digi 2 is a pure digitized mechanical instrument. It does not integrate any wireless synchronization system or profile export. (Score: 1/5)

O6 Compass & instruments (3.5/5)

Although it does not embed a digital compass, its sensors are remarkably reliable.

Sensors: It displays water temperature continuously (from -10 °C to +50 °C), features a precise electronic depth gauge, and an automatic dive stopwatch. (Score: 3.5/5)

O7 Robustness & depth (3.5/5)

Reliability is essential for equipment that hangs at the end of a hose and is often abused on the deck of vessels.

Materials: The casing is constructed of high-strength ABS plastic with a thermoplastic rubber boot. The screen has a specific "Bumpon" protector against scratches and front impacts. (Score: 3.5/5)

Operational depth: 120 meters (393 ft). (Score: 4/5)

O8 Price & service (4.5/5)

With a price point around 200 to 220 euros, this pressure/depth gauge console is a very smart investment compared to classic needle consoles that are often bulky, fragile to shocks, and devoid of remaining time calculation. (Score: 4.5/5)

The Smart Box: The console is sold with a Smart Box. By bringing this box near the Digi 2, a system of magnets allows you to interact with the device (to toggle from imperial to metric units, or force it into deep sleep mode for storage). Do not lose this storage box!

A simple depth redundancy: Never forget that purchasing this device implies that your decompression stop times are managed elsewhere (wrist-worn computer or planning on tables).

The use of a digital console, no matter how accurate its remaining air calculation, does not dispense with any fundamental precautions. The display of remaining autonomy in minutes is an excellent logistical aid, but the monitoring of these parameters must never justify a security relaxation. From the descent to the return to the surface, your manipulations – whether reading your screen data or adjusting a camera tray – must imperatively be performed while keeping the regulator in your mouth at all times, without exception. Attentive reading of your gas reserves ensures your safety, but the uninterrupted maintenance of your breathing source remains the absolute priority.

The Cressi Digi 2 is a superb reinvention of the traditional pressure gauge. By swapping old needles for a high-contrast LCD screen, it offers a clarity of reading that transforms the underwater experience, especially for divers whose arms are monopolized by camera gear. Its featherweight, automatic activation, and ingenious battery self-test system make it an irreproachable ally. Although it must be kept in mind that it does not replace a decompression computer, it constitutes the most comfortable and precise gas monitoring and backup instrumentation on the market in its price range.

The console runs on a standard CR2450 button cell battery. Thanks to its energy-efficient design, the battery life reaches a record 1000 hours of active underwater use. Cressi also offers a patented watertightness self-diagnostic system after battery replacement.
