In the world of scuba diving, choosing a dive computer is a decision that involves much more than just a budget. It's a matter of trust, safety, and suitability for your diving style. Every diver, whether beginner or experienced, seeks an instrument that will guide them accurately underwater without ever letting them down. With this in mind, we are taking a closer look today at the Aqualung i200C, a watch-style computer that promises interesting versatility for a wide range of divers.
The appeal of watch-style dive computers is undeniable. They offer discretion and everyday practicality that can be very attractive. However, it's essential not to be blinded by aesthetics. A dive computer must first and foremost be a reliable tool, where ergonomics and readability are never compromised, even in the most demanding conditions. The i200C presents itself as a solution that attempts to reconcile these two worlds: the elegance of a watch and the functional robustness of a decompression instrument. We will explore in detail whether this promise is fulfilled, by analyzing each aspect of its design and performance.

Algorithm & decompression stopsThe core of any dive computer lies in its decompression algorithm. The i200C incorporates the Pelagic Z+ algorithm (a direct derivative of the Bühlmann ZHL-16C dissolved gas model), known for its reliability and ability to safely manage recreational dive profiles. Its score of 4.0/5 reflects this algorithmic robustness. It offers the possibility to adjust conservatism, a crucial feature for divers who want to adapt their decompression profile to specific diving conditions or their physical state. The alarms, whether audible or visual via an LED indicator, are designed to be clear and immediately noticeable, even in noisy or low-visibility environments. While it doesn't offer free Gradient Factors, which might limit its appeal for advanced technical diving, it perfectly meets the requirements of recreational diving, where simplicity and safety are paramount. It is a wise choice for those seeking a reliable calculation base without unnecessary complexity.
Air & Multi-GasGas management is a crucial factor for divers who want to explore beyond air diving. The i200C allows you to manage up to two different Nitrox gas mixtures, with compatibility extending up to 100% oxygen. This capability is particularly valuable for experienced Nitrox training, offering the flexibility needed to optimize decompression stops. Its score of 2.2/5 reflects this versatility for recreational and light technical diving. However, the lack of wireless air integration is a point to consider. For divers accustomed to having their tank pressure displayed directly on their computer, this represents a change in habit. This model does not support Trimix or rebreathers, clearly positioning it as a tool for recreational diving and initial forays into light technical diving, without aspiring to use in heavy technical diving.
Screen & ErgonomicsThe ergonomics and readability of the screen are crucial underwater, where every piece of information must be accessible quickly and without ambiguity. The i200C is equipped with a segmented monochrome LCD, a choice that, while functional, offers less visual comfort compared to modern color displays. Its score of 2.7/5 highlights this limitation. However, the presence of four physical buttons is a major advantage. This configuration greatly simplifies navigation through menus and adjustment of settings, including Nitrox, even when wearing thick gloves. This is a significant improvement over models with one or two buttons, which can be frustrating to use. The screen size, inherent to the watch format, requires some adaptation, but the clarity of the segments and the adjustable backlight partially compensate for this limitation, ensuring adequate readability in most conditions.
Battery Life & PowerThe battery life of a dive computer is a major concern- especially during extended trips or cruises. The i200C uses a CR2430 battery (replaceable)- a standard battery that can be replaced by the user. This feature- rated 3.8/5- is a significant advantage. Being able to change the battery yourself- without having to go to a specialized service center- provides invaluable peace of mind. Furthermore- the dive computer retains decompression calculations in memory during battery replacement- preventing any loss of crucial data. This design prioritizes practicality and diver safety while traveling- minimizing interruptions and logistical constraints.
Connectivity & AppIn the digital age, connectivity has become a crucial factor in dive management. The i200C stands out with its built-in Bluetooth Smart chip, enabling seamless and reliable synchronization with the DiverLog+ app on iOS and Android smartphones. It excels in this area, boasting a rating of 4.1/5. This integration simplifies dive profile management, allows for remote device settings adjustments, and facilitates the download of dive logs. The ability for users to update the embedded software is also a significant advantage, ensuring that the computer always benefits from the latest improvements and bug fixes. This modern approach streamlines post-dive activities and device maintenance, making the user experience more enjoyable and efficient.
Compass & InstrumentsSome divers appreciate having a compass integrated into their dive computer, while others prefer a separate instrument. The i200C, with a rating of 3.1/5, chooses not to integrate a digital compass. This decision contributes to better battery life and a simpler design. It does offer a temperature sensor and four complete operating modes: Air, Nitrox, Depth Gauge, and Freediving. This versatility makes it suitable for various diving activities, even without an integrated compass. For divers who already use a separate compass or don't constantly need one, this omission will not be a major drawback. The focus is on the essential functions of decompression and dive profile management.
Durability & Depth RatingDurability is an essential quality for diving equipment, which is subjected to demanding environments. The i200C is certified for an operational depth of 100 meters, with a rating of 3.0/5.
