How Does The OCEANIC OCi Dive Computer Compare?

We wanted to see precisely how the OCi stacks up against the competition. So, we did some additional research and compared it to three popular dive computers from competitors. Here’s what we found.

Scubapro G2 Dive Computer

[amazon box=”B071252HH6″]

The fully customizable G2 wrist-only computer for scuba divers is one of the most versatile products manufactured by Scubapro. It’s equipped with an easy to use three-button user interface and several helper dive-related functions. You have a choice of multiple screen displays, with as little or as much info as you like. It has 485MB of memory and is capable of logging up to 1,000 hours of dive profiles.

This dive computer rates at up to 395 feet, that’s 100 feet less than the OCi. Customizations include light, classic, full, and graphical data presentations. Use this powerful dive computer’s technology however it suits you and your dive the best. The TFT screen uses less energy than many other dive computers, affording you extra-long 50-hour battery life. Also, there are 19 languages to choose from on the G2.

The Scubapro G2 Diving Computer has a 4 out of 5 stars rating based on Amazon customer reviews. This product also comes with a limited one-year manufacturers warranty. Also, the main two drawbacks that we found with the Scubapro G2 dive computer is that it’s rather expensive and doesn’t come with a screen protector.

Suunto D6i Novo Zulu Dive Computer

[amazon box=”B01MUG7XSJ”]

The D6i Novo Zulu dive computer is a product geared towards professionally oriented divers. Advanced dive functions such as a tilt-compensated 3D compass and live dive synching to Movescount.com. The ability to share info, still photos, and videos with the world while you’re under the water makes it a great dive computer for instructors.

Other key features include monitors for your cylinder pressure and air supplies via the computers wireless air integration system and DM4 software to save your dive data. Enjoy five different dive modes including air more, nitrox mode for one to three nitrox mixes, gauge modes, and free dive mode.

The Suunto D6i Novo Zulu Dive Computer has a rating of 4.4 out of 5 stars from Amazon customer reviews. This product also comes with a two-year international limited warranty. Furthermore, the main drawback that we found is that it has a high price tag for so few features.

Aqua Lung i450t Dive Computer

[amazon box=”B01CPNFYJQ”]

The Aqua Lung i450t is a hoseless gas integrated wrist watch dive computer. The Aqua Lung patented Gas Time Remaining Algorithm allowing for accurate real-time calculations of gas levels. Its multiple gas capability manages various Nitrox mixes with separate PO2 set points. The dive computer itself is mounted on a state-of-the-art wristband and has an intuitive design and easy to use interface.

Additional key features include a digital compass, with return bearings and declination adjustment, north reference, and free dive mode with dedicated memory. More or less the same compass as the OCi. Also, you can manage your diving depth, bottom distance, and surface times while in free dive mode.

The Aqua Lung i450 Dive Computer has a 5 out of 5 stars rating based on Amazon customer reviews. This product also comes with a 30-day satisfaction guarantee and a limited two-year warranty. The main drawback is that, for a high dollar dive watch, it doesn’t have as many features as you’d think it should.

Pros and Cons

Now that we’ve described the product in detail, as well as highlighting its competitors, let’s go over the pros and cons.


  • Easy to use interface
  • All the most cutting-edge features a diver could ever want
  • Air integration system
  • Advanced onboard digital compass
  • Extremely durable design
  • USB data transfer kit(an additional purchase with most dive computers)
  • Excellent aesthetics
  • Four customizable Nitrox gas mixes
  • Convenient buddy check function
  • Full user manual
  • Satisfaction guarantee
  • Two-year warranty


  • A high price range for casual divers
  • Dive log is limited to 24 dives
  • Has been reported to lose connection with the transmitter while in the water
  • Annual upkeep costs around $50

I want to mention that although high priced, there are very few dive computers on the market with so many features. And as far as annual upkeep goes, well, that’s the price for diving with such superior gear. Also, there isn’t a piece of wireless equipment on the market that doesn’t lose connection from time to time, which has more to do with the environment than the actual device itself.

The Verdict

There is no other diving watch quite like the Oceanic OCi dive watch. With such a fresh look, scores of super advanced features and uber functionality, all at a competitive price, what’s not to like? As technology steadily advances and becomes more affordable each year, the market continues to flood with inferior products. The Oceanic OCi dive computer is not one of them. Sure, you can find a dive watch for a quarter of the price. However, it won’t have even a quarter of the beneficial features nor the high durability.

If you’re a professional diver, or otherwise spend a load of time under the water, do yourself a favor and consider the long-lasting benefits of investing in the Oceanic OCi dive computer. You’ll thank yourself later. Want to check out the Oceanic OCi dive computer in person? Find an Oceanic Pro Dealer near you.
