I had this same computer new in 2005 and has been rugged and durable for the last 20 years. I am finally putting that one on the shelf and getting the new and improved. You can't go wrong with this one

Works and performs as it should. My family and I have been using Oceanic brand computers for many years. I like the layout and the simplicity of information display as well as the bar graphs and large numbers. Really, no negatives.the previous model on one of the kids? regulators flooded after about 5 years. Must have been operator error (didn?t change the O-ring for a while).

The device performed flawlessly in the initial dive. Numbers are large and easy to read without glasses or contacts. It provides a ton of information which I was happy about being a new diver. The only hiccup was that the two hexnuts under the collar were not properly tightened. This caused a leak and I could not use it in the second day of diving. That said the pros at Maui dive shop identified the issue and fixed me up in minutes. Truly not a big deal but something worth checking.

Love it but always been an oceanic dive computer guy. Very easy to read Set up wasn?t hard Doesn?t bt with ssi app but very few computers do Does everything I need it to and room to grow Wish I got the qd but could t justify the extra 150 just for that.

I love this computer. I use a GEO 2 also. But I do wish that the disconnect was standard and not an additional expensive add on. But the computer is great; muscle memory comes quickly.

This computer does everything that it is says it will, the numbers are easy to ready underwater, the compass works well and everything you need is in the box, at least it was for me. The battery seems to have a good life span too. If you want more features and a color display I also bought the Oceanic Pro Plus X with quick disconnect. It has more features, color display and a rechargeable battery. Expect the battery to need charging though as the color screen does use more energy. I was able to get 10-12 hours of use though between charges.

This is the newer model of the Oceanic computer Ive been using for the last eight years. I havent had any trouble with the previous model so I expect the same reliable performance from this computer. I bought this one for my wife. I really enjoy the easy to read display face in high and low visibility situations. Its also been great on night dives. The back light is a cool blue color that doesnt ruin my night vision. The progressive scales denoting "air time remaining" and "too rapid ascent" are easy to see and, therefore, are very useful. Im happy with this purchase.

Pro Plus 4.0
By Perry O.
I am new to diving and have found that the pro plus 4.0 is easy to work with and understand.
Bigger & better than ever, the ProPlus 4.0 features the latest Bluetooth 4.0 technology. Now divers can adjust & customize all their dive features on the go pre-& post-dive. ProPlus 4.0 boasts a new display area, wider font size, and 22% larger digits than its predecessor (ProPlus 3), making it clearer & easier-to-read than ever before. With Bluetooth compatibility, ProPlus 4.0 adds to Oceanic's commitment to growing the largest family of Bluetooth compatible computers available to divers.
Dive Computers are supposed to deliver crucial data quickly and w/o confusion. That is why the ProPlus 4 combines a huge display area. See it for yourself. Take the Oceanic challenge: When shopping for a new dive computer, compare the displays. When it comes to viewing critical information, which would you rather see at 100' (30 m)?
Air Time Remaining (ATR):
Air Time Remaining feature calculates current depth, tank pressure, breathing rate, ascent time, & decompression status to tell you exactly how much time you can remain underwater. The ProPlus 4 displays ATR via a numerical bar graph in addition to cylinder pressure. You may display ATR in oversized digits at any time w/press of a button.
Dive Time Remaining (DTR):
Dive Time Remaining, provides a 'real' number in minutes. This calculation combines ATR, nitrogen & oxygen absorption, displaying whichever allows less time. The ProPlus 4 features push button or automatic activation, triggered by water contact. A benefit of push button activation is easily verifying operation and cylinder pressure, but in case you forget, or simply choose not to activate your computer, it can be as simple as jumping in the water.
Audible alarms w/flashing LED warning light & acknowledgment:
The ProPlus 4 has a variety of system & user customized audible alarms, alerting you to situations that pose potential danger, or simply serve as convenient reminders. Have you ever had difficulty hearing your computer's audible alarm? Perhaps that little beep signifying a potentially dangerous situation was timed perfectly with some large exhaust bubbles rushing past your ears. Or maybe it seemed to be insignificant as that huge manta ray soared overhead. You won't miss the ProPlus 4's audible alarm. Once triggered, the alarm will sound continuously for 10 seconds. Oceanic knows what you are thinking That's nice, I'll definitely hear the alarm, but isn't that going to annoy me & everyone else in the water?" The alarm's job is to get your attention so that you look at the computer. Once it does that, simply press the button and it will stop. You are a responsible diver & Oceanic treats you that way. If you really want to exceed your pre-set maximum depth alarm by a couple of feet to capture that award-winning photograph go ahead!
Air or Nitrox:
The ProPlus 4 acts simply as an Air computer until you tell it otherwise, whether that is this weekend or 2 years down the road. As your training & experience grow, the ProPlus 4 is designed to grow with you, being easily programmed for Nitrox mixtures from 21% to 100%.
Oceanic Personal Dive Computer Algorithm:
Decompression theory can be trusted only as far as it has been demonstrated by actual test dive data. In 1987 a unique series of experiments were conducted by Diving Science & Technology (DSAT). Commissioned by Professional Association of Diving Instructors (PADI), these doppler ultrasound monitored human experiments conducted by Dr. Michael Powell produced the most comprehensive data set that exists for recreational divers to this day. These data were used to validate the PADI Recreational Dive Planner & are the basis of the algorithm used in all Oceanic personal dive computers. The ultimate adjustable algorithm that is the way divers, instructors & Oceanic Dealers refer to Oceanic PDCs. Oceanic's color coded bar graphs provide complete control of margin of safety for each dive. Want to be a bit more cautious? Make it a personal rule to never enter the yellow caution zone, or stay one pixel away, or you get the point. Now you can even program several of Oceanic's PDCs to do it for you w/Oceanic's patent pending nitrogen bar graph alarm; set it once & let computer alert you when bar graph reaches that level.
Automatic Safety Stop Prompt:
A brief audible & visual alarm remind you as you approach 15' (4.6m), & an automatic 3-minute timer counts down to zero. As in any other dive mode, you still have access to other pieces of information, & there is no penalty should you choose to disregard the safety stop.
Choose Your Dive Mode Display:
The new ProPlus 4 is as versatile underwater as it is topside. Upon starting your dive, the computer will simply display current depth, how long you can stay & cylinder pressure. While many divers have asked for such simplicity & ease of use, you know that with all the ProPlus 4's features, there must be more. And there is. Simply press the button to see more information. Is this information important to you on a full-time basis? Leave it there. Just want to check it & then move on to another display? You can do that too. It is up to you & your ProPlus 4.
Other features of the ProPlus 4 are: Fast set menu w/dual button operation, 12/24 hour format, date & time stamp, user friendly mode icons, graphic user interface recognizable logic of green, yellow & red color-coding in conjunction w/bar graphs, the diver has at-a-glance information, automatically compensation for altitude up to 14,000' (4,270m), diver replaceable CR2 battery, battery hot swap, 24-hour fly countdown & calculated de-saturation time, variable ascent rate indicator, depth dependent ascent rate, SmartGlo backlighting for low light conditions, 24 dive on-unit log book, optional Ocean-Log PC interface & PC upload, extended range gauge mode & much more!
The Oceanic ProPlus 4 can display in imperial or metric measurements, has an operational depth of 330' (100m), displays pressure from 0 to 5,000 psi (0 to 352bars) & displays temperature from 0 Degree to 99 Degree F (-9 Degree to 60 Degree C), comes in a durable impact resistant case w/attachment points for lanyards or clips w/a 7/16" threaded HP hose, & owner's manual.
The SideScan is a dual-purpose liquid filled compass. The SideScan window allows quick reference of large, easy-to-read bearing indicators on a luminescent display for gun sight accuracy. Or, for divers who prefer relative navigation, the ratchet bezel can be rotated easily even with thick gloves. The dial rests on a precision jeweled bearing & incorporates extremely strong magnets for super quick response & accuracy. The compass 360 Degree rotating bezel has compass headings in 30 Degree numbered increments & indicator marks for every 10 Degree. Bezel has twin heading indicators for alignment of compass course & lubber line across the compass face.
