VEO 1.0

Simple is as simple does. The Oceanic Veo 1.0 is a solid basic computer designed for air or single gas nitrox mixes up to 50 percent. It displays only essential information during the dive in easy-to-read digits; uses effective bar graphs to present nitrogen loading and ascent rate; and offers useful features like an automatic safety stop countdown timer that ticks off three minutes when you ascend to 15 feet. A single push button is all that's required to navigate the settings and the sequences are intuitive with help from the excellent owner's manual and waterproof prompt card. At this price point, you are giving up bells and whistles--most notably audible alarms, a backlight and the ability to download dive profiles--but these are excellent choices if you want a simple, low-cost computer.

Dual Algorithm Technology

Dual Algorithm Technology

Choose the one dive computer that’s liberal, conservative or middle-of-the-road.

Dual Algorithm™ technology lets you choose the decompression algorithm that best suits your diving needs without compromising safety.


repetitive deep and decrompression dive profile


Choose Pelagic DSAT for:

Liberal Recreational Diving

The Pelagic DSAT Algorithm safely maximizes dive time for repetitive, multi-level recreational diving. This algorithm relies on the human Doppler studies used to develop PADI’s Recreational Dive Planner (RDP), and has been the basis of our Dive Computers and other manufacturer's computer algorithms for many years. 

To add additional conservatism, you can also adjust the:

  • Tissue-Loading Bar Graph Alarm
  • Conservative Factor Setting


Choose Pelagic Z+ for:

Conservative Recreational Diving

When applied to standard recreational diving, the Pelagic Z+ Algorithm basis increases the conservative factor of the OC1 by 15-20%.

Liberal Repetitive Deep and Decompression Diving

The Pelagic Z+ uses the Buhlmann ZHL-16C database, which was conducted to meet the more rigorous demands of repetitive, cold-water decompression diving at altitude. The Pelagic Z+ mode maximizes dive times at depth without penalties.

Dive in sync with any buddy, anywhere.

Because the Dual Algorithm allows you to adjust the algorithm basis and its conservatism, you can adjust to closely match just about any other dive computer on the market, allowing you and any buddy to always dive in sync. Diving the same profile increases safety for both divers, and eliminates the need for one person to conduct a much longer or deeper stop when buddying with someone wearing a more liberal dive computer. On repetitive dives, there is no more waiting for the more conservative dive computer to clear. Both buddies will be ready to enter the water at the same time and can continue to dive the same profiles. You can’t control which dive computer your buddy wears, but you can control your ability to dive the same profile.

A note about deep stops:

Both algorithms allow (user ON/OFF option) credit for deep stops for No-Decompression dives in keeping with the data of Morroni et al (2004) and Bennett et al (2007).  No penalty is given if the diver skips the deep stop, but it is strongly recommended that a shallow safety stop be made with or without the deep stop in keeping with the experiments of Pilmanis (1975). 

It is important to note that neither algorithm provides deep stops for decompression dives since there is ample experimental data [Blatteau et al (2005), Gerth et al (2007), and Gutvik et al (2007)] that indicate that this practice often produces an increase in the risk of DCS.

easy to use
Review by Kathi (Posted on 10/19/14)
easy to use. however flooded as soon as warranty expired. Probably would go with something else
Okay Dive Computer
Review by Jeff Scott (Posted on 4/22/13)
New to dive computers. Bought this as part of the competitive package. Have already outgrown it. good for rentals, good for kids. Pain in the but to navigate through with only 1 button, No back light is a major concern especially when diving at depth in poor light, dive log is really lacking. Wish it displayed date of dive not just time...and then only 12 dives. Has not given me any problems but just really disappointed once I really started diving.
Very user friendly

This unit is easy to understand - operate - rely on
Easy to use computer for beginners
Review by scubabeat1955 (Posted on 1/18/12)
New to dive computers I purchased this easy to use VEO 1.0 and I'm happy with it. Not TOO conservative about deco-times compared to others and still keeps me out of DCS and/or Deco-Stops. Battery lasted more than 200 dives !!! Great beginners computer I can recommend.
