Oceanic Pro Plus 4.0 Console Computer

The Oceanic Pro Plus 4.0 is a premium console-mount dive computer that appeals to divers who prefer their data on the end of a hose rather than strapped to their wrist — and who want serious algorithm flexibility to go with it.

At $1,811, it's a significant investment, but console computers occupy a specific niche. Dive instructors, underwater photographers who can't spare wrist real estate, and divers who simply prefer the console form factor will find the Pro Plus 4.0 delivers a comprehensive package. The dual-algorithm system — letting you switch between Pelagic's DSAT and Z+ models — is its standout feature, offering a level of decompression planning flexibility that most wrist units in this price range can't match.

## Overview

The Oceanic Pro Plus 4.0 is a console-mounted dive computer that integrates directly into your regulator hose configuration, combining dive computer, SPG, and digital compass into a single console unit. It runs on Pelagic's dual-algorithm platform, giving divers the choice between the more liberal DSAT algorithm and the more conservative Z+ algorithm.

In Australian conditions, the console format has practical advantages. When you're gearing up on a pitching boat at the Cod Hole or struggling into a drysuit at the Rapid Bay jetty, having your computer attached to the reg means one less item to remember and one less thing to flood or drop. The large display is arguably easier to read than most wrist units, with data laid out across a generous screen that doesn't require squinting.

The dual-algorithm system is where the Pro Plus 4.0 genuinely differentiates itself. DSAT is the more permissive of the two, offering longer no-decompression limits — useful for experienced divers doing shallow repetitive dives on tropical reefs. Z+ adds deeper tissue modelling and tends to be more conservative, making it a better choice for cold-water diving in southern Australia where narcosis, thermal stress, and exertion are bigger factors. Being able to switch between the two based on conditions is a thoughtful feature that few competitors offer.

Compared to the Suunto Zoop Novo console, the Pro Plus 4.0 offers vastly more features but at roughly three times the price. Against wrist-mounted computers at similar prices, the trade-off is portability and daily wearability for screen size and integrated SPG.

## Key Features

- Console-mount design with integrated SPG and digital compass - Dual selectable algorithms: Pelagic DSAT and Z+ - Air, nitrox (up to 100% O2), and gauge modes - Large backlit display with multiple data screens - Digital compass with bearing lock and reciprocal heading - Adjustable conservatism settings on both algorithms - Altitude adjustable for freshwater inland diving - Audible and visual alarms for ascent rate, depth, NDL, and PO2 - USB connectivity for dive log download - User-replaceable CR2 battery

## The Good

- **Dual algorithm system provides genuine flexibility**: Switching between DSAT for warm, shallow reef diving in the Coral Sea and Z+ for cold, deep wreck diving off Victoria means you can tailor the computer's conservatism to actual conditions rather than accepting a one-size-fits-all approach. - **Large display is exceptionally readable**: The console screen is bigger than any wrist unit, and the data layout is logical. During a busy wreck dive with multiple things to track, being able to read depth, NDL, air pressure, and compass heading without cycling through screens is a real advantage. - **Integrated SPG eliminates wireless pairing hassles**: Your tank pressure is right there, mechanically connected, with zero chance of signal dropout. In overhead environments like HMAS Brisbane or the Loch Ard wreck, this reliability matters. - **Digital compass is well implemented**: The bearing lock feature is useful for navigating sandy flats or running search patterns. It holds calibration well and responds quickly to heading changes. - **Gauge mode for tech divers**: Running the computer as a bottom timer while using tables or a separate deco planner gives tech-leaning divers a flexible option without buying additional hardware.

## The Bad

- **Console format is inherently bulky**: There's no getting around the size. It dangles, it can drag across reef, and it takes up space in your gear bag. Streamlined divers and anyone doing tight swimthroughs will find it cumbersome compared to a wrist unit. - **$1,811 is steep for a console computer**: At this price you could buy a Shearwater Peregrine and a quality SPG with money to spare. The Pro Plus 4.0 needs to justify its premium through the algorithm flexibility and integrated format, which won't matter to everyone. - **No Bluetooth or wireless connectivity**: Dive logs transfer via USB cable only. In an era where most competitors offer app connectivity, the lack of wireless sync feels dated for a premium product. - **Not practical for daily wear or surface use**: Unlike wrist computers that double as watches, the console sits in your gear bag between dives. You lose the convenience of casual dive log review and surface interval tracking on your wrist.

## Verdict

The Oceanic Pro Plus 4.0 is a serious dive computer for divers who know they want a console format and are willing to pay for premium features within that form factor. The dual-algorithm system is its strongest selling point — the ability to match your decompression model to actual diving conditions is a meaningful safety and convenience feature that few competitors offer at any price. Dive instructors, underwater photographers, and divers who prefer console ergonomics will appreciate the large display and integrated SPG. However, the price is hard to justify for casual recreational divers, and the lack of wireless connectivity feels like an oversight on a unit at this cost. If you're committed to console computing, the Pro Plus 4.0 is one of the best available. If you're undecided on form factor, a quality wrist unit will likely serve you better.
