Your Review



Oceanic VEO 100 NX is a very basic and not an air-integrated dive computer that is suitable for beginners and as backup dive equipment. It has all basic features that dive computer must have to manage No-Decompression and Decompression modes of operation and diving with Air and Nitrox. Oceanic Veo 100 NX is similar to Aeris XR1 NX dive computer functionally.

You may find VEO 100 NX useful for backup device, but if you decide to have it as a main computer - be aware, that it doesn't have audio alarms and backlight.

Oceanic VEO 100 NX has only 1 control button on the user interface and by using only one button you will access and set variety of data and swap displays during the dive.

This dive computer has 3 bar graphs:

  1. Nitrogen Tissue Loading Bar Graph (TLBG) – this bar graph represents your nitrogen loading, and shows your No-Decompression and Decompression status. It is divided into the 3 zones – No-Decompression zone, Caution (No-Deco as well) zone and Decompression zone.
  2. O2 bar graph (O2BG) – this bar graph shows you the level of oxygen toxicity for a single dive, or accumulated oxygen loading for the last 24 hours. It appears if you set Veo 100 NX to Nitrox, i.e. set numerical value for FO2.
  3. Variable Ascent Bar Graph (VARI) – this bar graph gives you graphical representation of the ascent speed







Before diving you have access to variety of functions and settings provided by Oceanic VEO 100 NX. They include:

  • FO2 - Air, 21% - 50%;
  • Wet activation;
  • Units of measure;
  • Time and hour format;
  • PO2 alarm - 1.2 - 1.6 ATA in 0.1 ATA increments;
  • FO2 50% default


Also following functions are available:

  • Time to Fly countdown timer;
  • Time to Desaturate countdown timer;
  • Predive Planning Sequence;
  • Log mode;
  • Reset function

and they will be mentioned in Post-Diving Section of our review.

As you may see there are not many parameters to set, as it is really basic dive computer.







As a dive computer, Oceanic VEO 100 NX operates in 2 dive modes:

  1. Air;
  2. Nitrox


VEO 100 NX has several displays to give all information you will need either diving in No-Decompression or Decompression modes, and either with Air or Nitrox and to swap between them - press button.

Also upon reaching certain conditions during a dive you may get Safety Stop prompt, Violation conditions, or High PO2 and O2 alarms. And VEO 100 NX has all vital information displayed to manage all those conditions.

For fast ascent this scuba dive computer displays flashing TOO FAST message and all segments of VARI.

You may also get Safety Stop prompt, as I mentioned above with values of Safety Stop depth, Safety Stop countdown timer, and Stop bar icon in addition to what you have during No-Decompression mode on displays.


If you exceeded your No-Decompression depth and time limits – Oceanic VEO 100 NX turns Decompression mode to help you manage decompression correctly. And to do this you need to ascent to the depth displayed or to the depth a bit deeper than displayed and stay there for time that shown on the screen.

VEO 100 NX dive computer has special graphic representation for Decompression Stops management – UP and DOWN Arrows and a horizontal bar. If you are at exact depth required or stay within the limits of required depth – dive computer displays steady and solid both Arrows and a bar, if you surfaced to shallower depth – you will see DOWN Arrow and a bar (you may get into the Violation mode then), and if you’re deeper – UP Arrow and the bar.

Below is a summary of the values displayed on the main and alternative screens, you will have in the Decompression mode:

  • current depth;
  • required Decompression Depth and Decompression Time;
  • Total Ascent Time (TAT);
  • UP and DOWN Arrows and a Stop bar solid;
  • max depth;
  • Elapsed Dive Time (EDT);
  • time;
  • temperature;
  • PO2 value (if dive computer was set for Nitrox);
  • Decompression mode icon;
  • all other applicable icons and bars


During diving you may have violations during Decompression Mode. It means that you ascended to shallower depth than required for Decompression Stop and maybe stayed at that shallower depth for some time.

In that case you won’t get any off-gassing credits but instead you will receive a penalty time that must be worked off before you will get any off-gassing credit.

Oceanic VEO 100 NX dive computer has all applicable information displayed for each violation you may have, like Required Decompression ceiling Stop depth, UP/DOWN Arrows and Deco Stop bar, current depth, bar graphs and icons, and other data to guide you through those conditions.







After we used Oceanic VEO 100 NX underwater and appreciated its simplicity and user-friendliness, we may access following functions:

  1. Pre Dive Planning Sequence (PDPS) – this function shows you No-Decompression Limits (NDLs), according to your current nitrogen or oxygen accumulation from previous dives (if any), PDPS has range 9 - 57 meters in 3 meters increments;
  2. Time to Fly Countdown Timer;
  3. Time to Desaturation Countdown Timer;
  4. Log Mode – it stores data of your 12 most recent dives (battery removal does not make any affect on Log memory);
  5. Reset function - this feature allows you to do RESET to all data including Logs, and nitrogen and oxygen calculations – great beneficial feature if you use VEO 100 NX for rental and training purposes







Oceanic VEO 100 NX: What Divers Say


  • easy to learn, set up and use;
  • easy to read and intuitive display;
  • perfect dive computer as a main or for backup;
  • clear digits on display;
  • diver replaceable battery;
  • battery ‘hot swap’;

Even I mentioned above that this dive computer is perfect for the beginners, I want to emphasize your attention on one more thing – this dive computer doesn’t have audio alarms. And my personal point of view is that dive computer for newbie (who may be you) must have audio, because audio signal helps you stay aware of situation around – it grabs your attention in other words!

If dive computer doesn’t have an audio signal – how you can possibly know when it’s time to look down at your dive equipment if you do not have experience and do not know where and when to expect something coming? Will you hold dive computer in front of your eyes all the time and wait until something will flash on the display and miss picturesque view around at the same time?

It is not very convenient! And beginners do not have that experience that oldbies have and they do not know what to expect and when.

It is my personal opinion about audio in dive computers – if you are a beginner – you should buy dive computer with audio signal and with the backlight!

But if you do not care about this issue – don’t worry! Oceanic Veo 100 NX is still perfect dive computer that will never let you down – easy to learn and easy to use, and the price, especially for 3-gauge console, it’s like a gift!

Good For Entry Level or Backup

While ago I've bought VEO 100 Nx in a console with SPG to backup my Oceanic GEO 2. This dive computer is very easy to learn, set and operate. With 1 button easy access and not big menu structure I found it pretty convenient.

It is reliable in measurements and I don't have any complaints about its performance. Oceanic VEO 100 Nx so easy to dive with that I even bought second set for my youngest teenage daughter when she finished her OWD certification.

I recommend this dive computer as a backup dive computer for Oceanic or Aeris models, or as an entry level device.

Oceanic VEO 100 NX Good For Backup

I'm using this dive computer as a backup for Oceanic VEO 3 for 3 years already.

I am happy with this product. It has worked great so far on over 150 dives. It is easy to use and to read with its intuitive display and good owner's documentation.

Even I'm not a big fan of having just one button on user interface - for backup device Oceanic Veo 100 Nx works perfectly. And I recommend it as a backup for every diver who have Aeris and Oceanic units!
