Scubapro A2 Test: The technical watch that hides its capabilities well.

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

The idea of wearing a decompression device on the wrist, from the meeting room to the boat deck, holds a persistent fascination for many divers. This tangible connection allows us to maintain a physical link with our passion, even far from the ocean. However, the technical challenge is immense when it comes to condensing the necessary computing power for complex dive profiles into such a small volume.

The Scubapro A2 is precisely positioned at this complex intersection. It promises to combine the understated elegance of an everyday watch with the capabilities of an advanced multi-gas computer. The purpose of this analysis is to determine whether this seemingly appealing compromise holds up under pressure. We will dissect its algorithms, evaluate the readability of its reduced display, and verify whether this extreme miniaturization sacrifices safety in favor of style.

Overall score: 4.2/5

This computer is designed for: Technical divers or advanced recreational divers who require a device that can accompany them everywhere, both at sea and in the city.

This computer is not ideal for: Divers who have difficulty seeing things up close and need very large numbers to comfortably read their settings.

Algorithm and Levels (Score O1: 3.8/5)

The embedded mathematical model, the ZH-L16 ADT MB, is extensively tested and offers undeniable safety. Scubapro uses its proprietary version of the Bühlmann algorithm, which manages microbubble levels in an adaptive manner.

We regret the lack of direct and free adjustment of the Gradient Factors, as users are limited to the conservatism levels predefined by the manufacturer. This is sufficient for the vast majority of profiles, but it limits personalization for decompression purists. The microbubble system remains adjustable based on experience and physical condition, which provides a welcome flexibility. The display of the total ascent time is clear and precise.

Air and mixed gases (Oxygen score: 5.0/5)

This small watch hides a powerful calculation engine for deep-sea divers. It is capable of managing a complete range of bailout bottles, which allows it to be used on complex wrecks without ever being put out of commission.

The Scubapro A2 can simultaneously manage up to 8 gas mixes, offering Nitrox compatibility from 21% to 100%, full Trimix support, and a native CCR mode including 2 gases. Air integration is achieved wirelessly via low-frequency radio transmitters. This processing power is so impressive that it rivals much larger consoles.

Screen and Ergonomics (Score O3: 3.4/5)

The device's form factor inevitably imposes physical limitations. The monochrome LCD matrix display is well-defined and offers remarkable contrast, but the font size remains small.

Navigation is done via four metal buttons, which requires some practice when wearing thick gloves in cold water. The display is designed for the watch format, meaning that you sometimes have to navigate through menus to find secondary information. This is an inevitable compromise to maintain a wearable case size for everyday use.

Battery Life and Performance (Score O4: 4.0/5)

Unlike color watches that require frequent charging, the A2 provides peace of mind. Its replaceable battery system allows you to travel anywhere without a dedicated charger and offers several years of battery life with normal use.

It uses a CR2450 battery, which is easily replaceable by the user. The advertised battery life is up to 2 years or 300 dives. This energy independence is a major advantage for long trips or cruises where access to electricity may be limited.

Connectivity and Application (Score O5: 5.0/5)

Synchronization is all the rage these days. The integrated Bluetooth Low Energy chip allows you to download your dive log directly to your phone via the brand's app, in a completely seamless way.

The Scubapro A2 is perfectly compatible with the Scubapro software ecosystem on both computers and mobile devices. This seamless data transfer greatly simplifies dive log keeping and post-dive profile analysis.

Compass and Instruments (Score O6: 5.0/5)

It's one of the device's strengths. Despite its small size, the 3D electronic compass perfectly compensates for any tilt in the arm.

The computer also supports biometric data if you add a heart rate monitor strap. It includes a thermometer and offers six diving modes (Scuba, Gauge, Apnea, Trimix, Sidemount, CCR). Its sports mode with pedometer and swim stroke counter makes it a complete tool, even outside of the water.

Solidity and Depth (Score O7: 3.8/5)

The A2 handles pressure admirably for such a small size. It is certified to withstand very great depths without any structural weaknesses.

With a maximum operating depth of 120 meters, it meets the requirements of technical divers. The robust materials, including a strong strap, ensure considerable longevity against the effects of salt and sunlight.

Price and Customer Service (Score O8: 4.1/5)

The computer is priced within the expected range for technical dive computers of this caliber. The real advantage lies in the assurance of finding a Scubapro repair technician or spare parts at most dive centers.

The current price is around €600 without a transmitter. Scubapro has an excellent global network through its distributors. Exchanges are quick under warranty, although the quality of service sometimes depends on the involvement of the local dealer. This exceptional and responsive after-sales service coverage in the French-speaking European region provides peace of mind.

The Scubapro A2 is primarily aimed at technical divers or ambitious recreational divers who are looking for a versatile instrument. If you want a computer capable of handling complex decompression profiles with mixed gases while still being discreet enough to wear in an office environment, this is a very relevant choice. Its Trimix and CCR modes offer enormous potential for those considering moving on to more advanced types of diving.

On the other hand, this model is not recommended for divers whose near vision is starting to decline. The small size of the screen and characters requires good visual acuity, especially in low-light conditions or in murky water. If reading comfort is your top priority, a dive computer with a larger screen will always be a more suitable choice.

Buying a dive computer is a long-term investment, and the quality of after-sales service is a crucial factor. Scubapro relies on an excellent global network through its authorized dealers. In case of hardware problems, warranty replacements are usually quick and efficient.

It is important to remember that the after-sales service experience largely depends on the quality and involvement of the local reseller who will act as a link with the brand. In French-speaking Europe, coverage is dense and responsive, which allows you to have your equipment maintained or repaired without excessive delays. This is a significant advantage compared to brands with less distribution.

The choice of power source is crucial depending on your diver profile. The Scubapro A2 uses a standard CR2450 button battery that can be replaced by the user. This solution offers several years of battery life under normal use, which is very reassuring.

For long trips or diving cruises, this energy independence is a major advantage. You don't have to worry about finding an electrical outlet or carrying a specific charger. Simply slip a spare battery into your bag for peace of mind. However, be aware that if you use the wireless air integration, the transmitter will consume its own battery, which also needs to be monitored and replaced periodically.

If the A2 format appeals to you but you're looking for a color interface, you might be interested in the Scubapro Galileo 3 (G3). For those who prefer a larger display and maximum readability, the Scubapro Galileo 2 (G2) remains an essential reference in the brand's range.
