Oceanic VEO 250 is the basic and not an air-integrated dive computer that is perfectly suited as for beginners and for advanced divers who like an easy and quick set up dive equipment. VEO 250 can be used as a main dive computer or for backup. It has been in scubadiving market for quite a while, I think, since the beginning or middle of 2000’s.

It is worth to say that VEO 200 and VEO 250 dive computers have the same functions and features, except interactive control panel.

VEO 200 was made to be fitted into the boot and its control buttons were located on top of the module, but Oceanic VEO 250 has option to be worn as a wrist dive computer, so its buttons located differently – one ADVANCE is on top, another button SELECT – takes position on the right side.

Oceanic VEO 250 scuba dive computer has 2 buttons on the interactive control console – ADVANCE and SELECT. And by using them you can access and set variety of functions, swap main and alternative displays, activate backlight, acknowledge audio.

This dive computer has 3 bar graphs to keep you up to date with data about nitrogen loading, oxygen toxicity and speed of your ascent:

  1. Tissue Loading Bar Graph (TLBG) – this bar graph represents your nitrogen loading, and shows your No-Decompression and Decompression status. It’s divided to colour zones – green zone – No-Decompression status, yellow – Caution (No-Decompression), red – Decompression conditions.
  2. O2 bar graph (O2BG) – this bar graph shows you the level of oxygen toxicity from a single dive, or accumulated oxygen loading for the last 24 hours.
  3. Variable Ascent Bar Graph (VARI) – this bar graph gives you graphical representation of the ascent speed. It’s divided to colour zones – green zone – Normal rate, yellow – Caution rate, red – too fast.







On surface you will have an access to variety of functions of Oceanic VEO 250 (Time to Fly and Time to Desaturate, Log Mode, PC interface and Predive Planning Sequence (PDPS), Reset function) and you may set variety of parameters, which divided into Mode 1 and Mode 2.

Oceanic VEO 250 operates in 3 dive modes:

  1. Air;
  2. Nitrox;
  3. Gauge Mode – in this mode Veo 250 functions as a depth gauge and timer only and doesn’t perform calculations for nitrogen absorption and oxygen accumulation

For each mode you set, dive computer has several displays to keep you well-informed about current situation. To swap displays I needed to press ADVANCE control button that is located in front.

During No-Decompression dive you may get Automatic Safety Stop prompt. At that moment you will hear Oceanic VEO 250 beeping and it will show you display with appropriate data, like Safety Stop Depth and Safety Stop Countdown timer.

If your ascent is too fast – scuba dive computer will give Ascent rate alarm with all segments of VARI flashing and in the red zone with audio signal, and red LED flashing as well.


If you exceeded theoretical No-Decompression Limits – dive computer will turn to Decompression mode and help you perform your decompression correctly. For Decompression it has few displays with related data and you need to press Advance button to see all of it.

After you got this Decompression message from VEO 250, 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.

Oceanic VEO 250 has special graphic representation for Decompression Stops management – UP and DOWN Arrows and a horizontal bar. For example, if you hit exact depth required or stay within the limits of required depth – dive computer displays steady 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 – easy as it is!

Below is a summary from main and alternative displays for Decompression Mode:

  • current depth;
  • required ceiling for Decompression Stop Depth and Decompression Stop Time;
  • Total Ascent Time (TAT);
  • Deco Stop icon (arrow and bar);
  • Elapsed Dive Time (DTR);
  • max depth;
  • temperature;
  • time;
  • PO2 value (if Veo 250 was set for Nitrox);
  • all applicable icons, etc.


You may create 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 a while.
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.

Upon reaching certain conditions, you may have High PO2 warning/alarm and High O2 warning/alarm. Oceanic VEO 250 designed to help you out in these situations as well, by displaying all related values and bar graphs, like PO2 value, flashing segments of O2BG and UP Arrow, current depth and DTR in the first case; and flashing full O2BG and UP Arrow, O2 DTR is displayed as 0 (zero) in second case.


Oceanic VEO 250: Diving In GAUGE Mode

VEO 250 dive computer may be set for Gauge Mode. It means that it will work as a depth gauge and timer only and won’t calculate any nitrogen and oxygen loading. In Gauge Mode you may use this dive computer for freediving as well.

When Oceanic VEO 250 is set for Gauge Mode, its maximum depth increases to 120 meters (400 ft). In this mode you will get main and alternative displays with following data:

  • current depth;
  • max depth reached;
  • Elapsed Dive Time (EDT);
  • temperature;
  • time;
  • VARI (when ascending)


Back to Top







After the Transition Period you will have access to following functions:

  1. Pre Dive Planning Sequence (PDPS) – this function shows you No-Decompression Limits (NDLs) - depths and times, according to your current nitrogen or oxygen accumulation from previous dives (if any);
  2. Time to Fly Countdown Timer;
  3. Time to Desaturate Countdown Timer;
  4. Log Mode – it stores data of your 24 most recent dives (battery removal does not make any affect on Log memory);
  5. PC interface – this function allows you to download data from Oceanic VEO 250 to PC by using special cable and software;
  6. 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 250 for rental and training purposes;
  7. Dive Simulator Mode – what can be better than learn your dive computer in variety of diving situations without going underwater! This function allows you to do so, by entering data and observing the dive computer’s response, and how it displays certain information for different diving scenarios.

Oceanic VEO 250 Does Everithing For Me! Perfect Specs-Price Combination

I've been using this dive computer all around the US and Europe dive sites and I've logged 500 dives on my Oceanic VEO 250 already. It never failed me, works as a real expensive swiss wrist watch! With SPG and compass in console I don't really need another device underwater.

I learnt it rather quick - 2 buttons user interface was quite easy to comprehend. Its coloured bar graphs are very good visual help for me. Display area is large enough to see the numbers at any angle without interference. Quick Disconnect feature is a great idea to store safely dive computer from my other dive gear.

If you are just recreational diver - you really don't need anything else to stay safe and well-informed!

Oceanic VEO 250 Is The Easiest And The Most Reliable Dive Computer I've Ever Used

I've dove commercially with this computer for the last 6 years. Air and Nitrox, I'm about to replace my 2nd one. I'd like an automatic backlight, but that's my only complaint.

Used many other dive computers, and compared many others algorithms, and this is easily the most liberal that I've come across. Aside from the Genesis models. They are exactly the same. 57 min at 60'. After about 1000-1200 jumps, the algorithm goes quite conservative. I'm now getting only 37 min at 60'. Hence replacing it.

About the same time I start wondering about depth gauge accuracy. +\- 1 or 2'. It's been flooded, bent misused, abused trampled and tossed around, and is entirely bomb proof. I can't believe it still works. Aside from price, this is still the best computer I've ever had.

And I've used Suuntos, UWATECs, Genesis, and other Oceanic models. By far the most user friendly and reliable dive computer I've seen.

But be careful. It's algorithm is liberal, and I have seen guys show DCS symptoms inside DECO limits on air repets. Ones succeptibility to DCS is very personal, but to me, time is money and it still keeps you well within navy tables.
