Air Time Remaining  The Air Time Remaining feature calculates current depth, tank pressure, your breathing rate, ascent time, and decompression status to tell you exactly how much time you can remain underwater. The Pro Plus 3 continually displays Air Time Remaining via a numerical bar graph in addition to cylinder pressure. You may also display Air Time Remaining in oversized digits at any time with the press of a button.   Dive Time Remaining Dive Time Remaining, like Air Time Remaining provides a 'real' number in minutes. This calculation combines Air Time Remaining, Nitrogen and Oxygen absorption, displaying whichever allows less time.   Choose Your Dive Mode Display  The new Pro Plus 3 is as versatile underwater as it is topside. Upon starting your dive, the Pro Plus 3 will simply display your current depth, how long you can stay there and cylinder pressure. While many divers have asked for such simplicity and ease of use, you know that with all the Pro Plus 3'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 and then move on to another display? You can do that too. It's up to you and your new Pro Plus 3.   Water or Manual Activation  Is it a good idea to check your computer before entering the water? You bet. Could you forget to activate your computer? Sure. The Pro Plus 3 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 with Flashing LED Warning Light  The Pro Plus 3 features a variety of system and user-customized audible alarms, alerting you to situations that pose a potential danger, or simply serve as a convenient reminder.   Audible Alarm Acknowledgement™  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 Pro Plus 3’s audible alarm. Once triggered, the alarm will sound continuously for 10 seconds. We know what you’re thinking… “That’s nice, I’ll definitely hear the alarm, but isn’t that going to annoy me and everyone else in the water?” We thought of that too. 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’re a responsible diver and 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 Pro Plus 3 acts simply as an ‘Air’ computer until you tell it otherwise, whether that is this weekend or 2 years down the road.    Automatic Safety Stop Prompt A brief audible and visual alarm remind you as you approach 15 feet. An automatic 3-minute timer counts down to zero. As in any other dive mode, you still have access to other pieces of information, and there is no penalty should you choose to disregard the safety stop.   FastSet™ Menu System  Speed through menu items and set modes easily and quickly with Oceanic’s FastSet Menu and intuitive dual button operation.   Graphic User Interface™  Using the recognizable logic of green, yellow and red color-coding in conjunction with bar graphs, the diver has at-a-glance information. As easy to understand as a traffic light, the Graphic Diver Interface helps you to easily monitor No-Decompression status, Oxygen Accumulation, Ascent Rate, and Air Time Remaining.   Automatic Altitude Compensation  All Oceanic computers automatically compensate for altitude up to 14,000 feet, giving adjusted no-decompression times and depths. They even automatically recalibrate the depth display for freshwater instead of seawater.   Diver-Replaceable Batteries All Oceanic computers feature diver replaceable batteries. This can be a real trip-saver on board a live-aboard boat!   24-Hour Fly Countdown and Calculated Desaturation Time The Pro Plus 3 features both a dual 12-hour countdown timer and calculated Desaturation Time, the theoretical time required to off-gas all residual nitrogen at sea level.   Variable Ascent Rate Indicator™  Some computers simply flash an icon, telling you that you’re ascending too quickly. The Pro Plus 3’s Variable Ascent Rate Indicator bar graph acts as a speedometer, allowing you to very precisely control your ascent rate via the green, yellow, and red bar graph.   Depth-Dependent Ascent Rate The Pro Plus 3 features a depth-dependant ascent rate, allowing increased rates at deeper depths and providing additional safety as you near the surface.   SmartGlo® Backlighting  Want to verify your set mode options before your night dive? Press the SEL button to activate the backlight and go ahead! A small photo-sensor in the face of the Pro Plus 3 analyzes the intensity of ambient light each time another button is pressed. If it’s dark, SmartGlo backlighting will be there for you when you need it, and it will preserve battery life when you don’t.   50 Dive On-Unit Log Book  The Pro Plus 3 features on-unit data storage capacity for 24 dives. Date and time stamp makes locating and viewing a specific dive quick and easy.   Optional OceanLog® PC Interface  The Pro Plus 3 features a watertight, plug-in serial connection for fast and reliable PC download. Optional OceanLog software provides intuitive post-dive analysis and logging. You have the option to add and/or edit many pieces of information to customize your log book, with data such as depth and decompression status during a dive, maximum depth, bottom time, air consumption, air time remaining, no-decompression status, descent and ascent rate, surface interval, and any violations recorded automatically.   Optional PC Upload In addition to detailed dive analysis, the optional OceanLog PC Interface also allows you to quickly and easily set all of your Pro Plus 3 settings and options directly through your PC.   Extended Range Gauge Mode  Divers using advanced breathing gas mixtures or otherwise conducting planned dives beyond the operational limits of the computer may utilize the Pro Plus 3 as an advanced air integrated digital depth gauge and bottom timer with detailed PC Interface.       Largest, easiest-to-read display available - anywhere. Patented Air Time Remaining algorithm provides extremely accurate time based on current depth and your personal air consumption Dual Algorithm Custom alarms Quick disconnect SmartGlo® Backlighting Fresh water and salt water calibrations 3 gases - NX to 100% Deep stop Adjustable safety stop settings Log saves detailed dive data for last 50 dives Data Retention - maintains calculations indefinitely when the battery is changed Review Card Manual

The iDive series integrates the real and complete Algorithm to calculate your current tissue saturation and afterwards decompression profile in real time. This allows to obtain reliable and very safe decompression profiles.Most dive computers algorithms make interpolation of stored data to calculate decompression profiles of the dive profile made by the diver. A cheap way to do it, but you have to adapt your dive to the profiles stored in the dive computer. The iDive is neither more nor less conservative in comparison with the other computers. It is just "right". Repetitive dives management.More dives a day in more days: no problem at all. Featuring the Real time Algorithms the iDive calculates your real tissue saturation status and calculates your repetitive dive profile according to your previous dives.This means that your profile is always optimized, even after more days of repetitive dives.
