Oceanic VEO 3.0 Metric Dive Computer with Compass

A dive computer tracks the actual depth and time profile you have dived and the tissue loading that follows from it, which is personal to you. A rented computer has no record of your recent diving, and swapping models each trip means relearning the display and menus when you should be focused on the dive. Owning one you know well is a genuine safety and comfort improvement.

No. A computer only tracks the profile of the diver actually wearing it, and even buddies who stay together do not follow identical depth and time profiles. Every diver needs their own computer, and passing one between divers or between dives is unsafe.

Conservatism settings make the computer's calculations more cautious, shortening allowed bottom times and adding margin beyond the base algorithm. Divers commonly add conservatism for factors such as cold, hard work, fatigue, or repetitive multi-day diving. How and when to adjust it is covered by your training and your computer's manual, so set it before you get in the water and follow what your computer tells you during the dive.

Broadly there are two types: user-replaceable batteries, often a coin cell that you or a shop swap along with resealing an o-ring, and sealed rechargeable batteries that charge from a cable or dock. Neither is universally better, as replaceable cells are convenient on remote trips while rechargeables avoid ever opening the case. Follow the manual exactly for any battery change, because an improperly seated o-ring or case is the usual cause of a flooded computer.

Yes, both change the picture, and both are governed by your training agency's guidance and your computer's instructions rather than any casual rule of thumb. Many computers have an altitude setting that must be configured before diving at elevation, and most display a no-fly or surface-interval countdown after a dive. Follow your computer and your training, and ask a dive professional or a dive-medicine specialist if you are unsure.

Rinse it in fresh water after every dive day, paying attention to the buttons and around any sensor openings where salt crystals form, and let it dry fully before storing. Keep it out of prolonged direct sun and extreme heat, and avoid pressing buttons while sand is on the case. Inspect the strap or bungee often, because a failed strap loses far more computers than a failed computer does.

A wrist computer is worn like a watch and read by raising your arm, while a console computer sits at the end of a hose with your other gauges. Air integration means the computer also displays cylinder pressure, either through a hose or from a wireless transmitter on the first stage, and often estimates remaining gas time. All of them run a decompression algorithm, so the real difference is where you read the information and how much of it you get.

No. The VEO 3.0 is a legacy Oceanic dive computer and is no longer listed among Oceanic's active products. Manufacturer support continues through the operating manual, firmware-update notices and accessories such as the replacement boot and wristband. Because availability of legacy configurations like the console with compass, SKU 04.3825.16, can change, call 888-701-4017 or chat with us to confirm what we can supply.

NORM mode handles air and nitrox diving with full decompression calculations and supports up to two nitrox mixes. GAUGE mode presents depth and time with a run timer, with a listed depth range to 400 FT / 120 M. FREE mode is for freediving. You move between modes and settings using the three control buttons, 9 menus and 29 set selections.

The VEO 3.0 uses Oceanic's Dual Algorithm, which lets you select either Pelagic DSAT or Pelagic Z+ as the basis for its decompression calculations. The Dual Algorithm lets you select Pelagic DSAT or Pelagic Z+ as the basis for decompression calculations; the operating manual explains how to set it. Your training agency's guidance and the VEO 3.0 operating manual govern how to set it.

Yes. The VEO 3.0 works with Oceanic's OceanLog PC interface software, connected using the VEO USB Interface Cable. The computer's firmware is also user upgradeable, so revisions published by Oceanic can be applied without sending the unit in. Contact us at 888-701-4017 if you need help identifying the correct interface cable for your unit.
