Whether you are new to the world of scuba diving or have been going underwater for years, you know how compelling diving can be. Even though scuba is one of the most exciting athletic pursuits anyone can do, it is also dangerous. To ascend and descend safely you need access to important information. Fortunately, you don’t have to do difficult mathematical equations to find your no-decompression limit. Instead, you can rely on a dive computer to do the tough math for you.

There are a variety of dive computers available for purchase today. Like with other pieces of scuba equipment, not all dive computers are a good investment. How do you know the difference between a high-quality device and an inferior one? That’s where we come in.

In this review, we take a deep look at the Oceanic OCi dive computer. Continue reading for answers to some common questions about dive computers and an honest assessment of the performance capabilities of the Oceanic OCi.

What Is a Dive Computer?

If you haven’t been around the scuba community long, you may not know what a dive computer is. Simply, a dive computer is an electronic device that divers wear during dives. Sometimes scuba enthusiasts refer to dive computers as decompression computers or decompression meters. Regardless of what you call the device, the purpose of wearing one is clear.

As you probably know, diving too far too quickly or ascending at rapid rates can wreak havoc on the human body. Dive computers keep divers safe by measuring the depth and duration of underwater dives. Devices then input this information into an algorithm to determine a diver’s safe-ascent profile. This information is vital for helping divers avoid decompression sickness during and after dives.

Most dive computers work the same. When calculating a safe-ascent profile for a diver, they measure underwater ambient pressure in real time. Once the information feeds through the algorithm, the computer indicates how much time the diver has before reaching a specific no-decompression limit. If the diver surpasses the NDL, the dive computer tells the diver how to safely return to the water’s surface.

Dive computers have a variety of functions. While entry-level computers collect relevant information about underwater conditions and dive length, advanced ones have additional features. The dive computer that is right for you depends on your scuba experience and diving goals.

What Is the Oceanic OCi Dive Computer?

The Oceanic OCi is a high-end dive computer. While the dive computer works great for divers of all experience levels, it is specifically valuable to experienced divers. That is, if you purchase this dive computer, you have access to a variety of innovative features that are most useful in dynamic diving situations. As you may suspect, the Oceanic OCi isn’t cheap. As such, if you are a diving novice, you may be better off purchasing an entry-level dive computer and some other gear instead of investing in the high-end Oceanic OCi. We discuss pricing for this dive computer in greater detail later in this review.

The Oceanic OC1 is one of the most expensive dive computers on the market. The company’s OCS is one of the best-selling devices. Our computer, the Oceanic OCi is a combination of the two. While the OCi doesn’t have the expensive titanium frame that is standard on the OC1, it does virtually everything the OC1 does. For budget-conscious divers who want a high-performance dive computer, the OCi is a good option.

Like other Oceanic dive computers, the OCi is a wrist-worn device. The OCi screen is mostly LCD, giving divers a clear display to quickly read important information. The most essential information is displayed on the main screen. This includes gas selection, dive depth, NDL, remaining dive time and variable-ascent rate. You can toggle to additional screens to view other information, such as water temperature.

Using the Oceanic OCi underwater is easy, even if you wear gloves. The device has four stainless-steel buttons that are responsive without being overly sensitive. When you are on the surface, hitting the buttons makes a mechanical clicking noise. As such, you certainly know whether you are moving between screens or changing device setup.

Calibrating the computer and setting up dives are easy processes on the Oceanic OCi. The device works by either requiring the diver to press or hold down a button. After watching an instructional video or reading through the comprehensive user’s manual, successfully navigating the OCi’s menus becomes essentially intuitive. Also, you can choose to activate the computer with either the push of a button or by exposure to water. As such, if you are prone to forgetting to initiate a dive, you can rely on water to do it for you. If you prefer to use a free-diving mode, the OCi has you covered there as well.

Reading a dive computer underwater isn’t always simple. Oceanic addresses this problem by backlighting the OCi. Even in dark conditions, readability remains excellent. It is no surprise that both cave and deep-water divers use the Oceanic OCi. If you are concerned about the backlight draining the battery on the device, you don’t have to be. The OCi has a sensor that automatically brightens and dims the light depending on lighting conditions. When you don’t need the backlight, it turns off to conserve battery power.

The Oceanic OCi has an integrated compass that clearly displays the direction you are heading. This is an invaluable tool for scuba guides and teachers. If you work in the rescue sector, you are also likely to appreciate the included compass on the Oceanic OCi. Additionally, the OCi has a decidedly heavy-duty feel to it. The bezel and strap are both high-quality, with each capable of holding up to considerable punishment. Moreover, the screen is made from high-density acrylic, allowing it to resist both breaks and scratches.

Additionally, the OCi includes a wireless air transmitter. This feature is apt to change the way you dive. The transmitter gives you two critical pieces of information. First, it determines how much air you have remaining after measuring dive depth, breathing rate, decompression status, tank pressure and other factors. Likewise, the wireless air transmitter calculates dive time remaining. Both of these calculations are handy, as they give you at-a-glance safety details about your dive.

When you are shopping for a dive computer, you must think about your underwater goals. After all, it is easy to spend a small fortune on features you simply don’t need. Still, the best way to understand the functionality of the Oceanic OCi is to compare it to a couple other dive computers. Below, we measure the OCi against a high-end and an intermediate dive computer.

Comparing professional-grade dive computers quickly becomes an exercise in futility. Most feature heavy-duty construction, a variety of features and smart design. The SCUBAPRO GALILEO LUNA is one such dive computer. This one has everything the Oceanic OCi has under a different brand. If you have brand loyalty to SCUBAPRO, you will probably be inclined to purchase this device. If not, the Oceanic OCi is a bit more affordable and equally as good.

If you are looking for a functional dive computer that doesn’t cost quite as much as either the Oceanic OCi or the SCUBAPRO GALILEO LUNA, the Mares Quad dive computer is worth consideration. While decidedly more limited than high-end dive computers, the Mares Quad has enough features for most entry-level and intermediate divers. We like the overall styling of this watch. It is also easy to use with a large, clear display. Unfortunately, if you work in the scuba sector or are a recovery diver, the Mares Quad dive computer likely won’t work for you.
