What We Think

The Oceanic Dive Computer VEO 2.0 does the job on most fronts. It won’t blow you away, but it won’t disappoint either. With both diving and freediving modes, you can use it for both, or you can even use the gauge mode as a bottom timer if you want to use it on technical dives.

What We Think

The Oceanic Dive Computer Pro Plus X is a premium computer with a host of features but comes at a hefty price. When you factor in that the ProPlus X is primarily a recreational diving computer, that is priced at the same level as a high-end technical diving computer; it is not great value for money. If you are willing to spend the money, you are better off picking up our top of the range option.

That being said, if you love console-mounted computers and want the latest cutting-edge machine, then the Oceanic Pro Plus X is the beast for you.


  • Huge screen with clear display
  • Large display numbers easy to read for everyone
  • Rechargeable battery saves time and effort
  • Quick disconnect makes storage and transportation a breeze


  • Limited operational depth (330ft/100m) means no Tec diving with the ProPlus X

Buyer's Guide

When it comes to scuba diving computers, the key is functionality and scalability. Ask yourself: what does the computer do and how does that fit with the kind of diving you are doing? Does the computer provide all the information you need? Do you often use Nitrox and what percentages? Do you switch gases underwater?

Also, don’t forget about the algorithm powering the unit. Is it conservative enough, is it adjustable, and what is its safety track record in the type of diving you do? These are questions you should always look into, before making a purchase.

You also want to factor in scalability, and how do you see your diving developing. Ask yourself: are you interested in going tec, do you like the idea of rebreathers and mixed gases? Can you see yourself doing this type of diving a few years down the line? You are always best off choosing a computer that can grow with your diving abilities and expertise.

The world of diving computers can be very confusing; there is a vast number on the market, and each has a large amount of detail and technical data available that can make choosing the right one a difficult task.

Luckily, we have done the hard work. If you are a big fan of Oceanic and love console-mounted computers, then the ProPlus and ProPlus X are good options. However, when it comes to Oceanic Dive Computers other line ups, they do not present the best value for money or performance. You can often find higher or similar specs for a lower price. The one main exception is Oceanic’s Dive Computer F10 freediving computer which represents excellent value for money and is a great unit.
