Oceanic Proplus X Air Integrated Console Dive Computer

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.

The ProPlus X operates in AIR, NITROX, and GAUGE modes, letting one computer cover standard air diving, enriched-air nitrox diving, and bottom-timer gauge diving. The unit's four push buttons and TFT display provide an interface for managing settings during a dive.

Yes, the ProPlus X uses Bluetooth 4.0 to connect wirelessly to Oceanic's DiverLog app, which lets you adjust settings, view dive logs, and store dive details without cables or a separate download device. OceanLog PC download is also available as an optional method for saving dives, with capacity for up to 150 dives.

The ProPlus X uses a lithium-ion rechargeable battery rated for 35 to 60 hours of use between charges, depending on use and settings. It charges through the included USB/mini USB charger cable and charger connection module.

The ProPlus X ships with the console computer itself, a charger connection module, a USB/mini USB charger cable, a screen protector, a zippered protective storage and carrying case, and a high-pressure hose with quick disconnect. It is covered by a 2-year warranty on the dive computer.
