Oceanic VT3 dive computer has 3 buttons on the interactive control console: MODE, ADVANCE and SELECT. As this dive computer has too many functions and only 3 buttons to call those functions out – you should spend quite a time to study all buttons’ purposes and their combos to get of what you expect under water in order not to be confused later!

Oceanic VT3 has 3 bar graphs that represent nitrogen loading (TLBG), oxygen accumulation (O2BG), and VARI (variable ascent indicator). Below you may see short descriptions each of them:

  1. Tissue Loading Bar Graph (TLBG) – shows nitrogen loading during dive and after. When diver goes deeper and stays longer his/her nitrogen level increases and dive computer adds new segments to this bar graph, and when person ascends or performs decompression – nitrogen level decreases and dive computer takes away segments; 8 segments – Decompression mode;
  2. Oxygen Accumulation Bar Graph (O2BG) – shows oxygen toxicity level if Oceanic VT3 was set for Nitrox. It works the same as a TLBG – adds and subtracts segments; it stores information about oxygen accumulation for the last 24 hours and if you exceed the allowable limit - all 5 segments will be flashing;
  3. Variable Ascent Rate Indicator (VARI) – this graph shows your ascent rate

 

If FO2 is set only to Air, O2BG will not be displayed during any dive and PO2 values and warnings will not be shown either.

 


 

 


 

 


 

Before diving and from Surface Main we will access and set up Oceanic VT3. All settings divided into the certain groups, like group of alarms and utilities, for example. Below is the summary of what we may set at this stage:

  1. FO2 MIX 1 - MIX 1 - Air, 21% - 50%; MIX2 - Air, 21% - 100%; MIX2 - Air, 21% - 100%;
  2. Depth alarm - 10 - 100 meters in 1 meter increments;
  3. Elapsed Dive Time (EDT) alarm - 10 - 180 minutes in 5 minutes increments;
  4. Tissue Loading Bar Graph (TLBG) alarm;
  5. Dive Time Remaining (DTR) alarm - 0 - 20 minutes in 1 minute increments;
  6. Turn Pressure alarm (for Transmitter 1 only): OFF / 1000 psi – 3000 psi in 250 psi increments;
  7. End Pressure alarm (for all Transmitters): 300 psi – 1500 psi in 100 psi increments;
  8. PO2 alarm: 1.2 ATA – 1.6 ATA in 0.1 ATA increments;
  9. Units of measurement;
  10. Time and date;
  11. Safety Stop parameters: depth and time;
  12. Personal Conservative factor – ON/OFF;
  13. Backlight duration: 0/5/10 seconds;
  14. Sampling rate - 2/15/30/60 seconds;
  15. Transmitters linking code, etc.

 


 

 


 

 


 

Oceanic VT3: Diving With Air & Nitrox

During dive in any mode you will have an access to several displays that Oceanic VT3 provides – main and alternative, plus you may have more of them if you get into the stage when you may have Safety Stop prompt pops up (if you set it ON initially), or different alarms start coming, or violation modes.

 

Oceanic VT3 NO-DECO Card

Upon reaching certain conditions - Oceanic VT3 will display Safety Stop prompt with Safety Stop Depth and Countdown Timer, if we set Safety Stop option to ON.

During Normal dives (Air or Nitrox) you have access to Switch gases and Buddy Pressure check functions. And it works great, if you set up your Transmitters links properly and there are no missing signals.

 

When we exceed our No-Decompression Limits (NDLs) - scuba dive computer will activate Decompression mode to help us decompress correctly and resurface safely.

Below you may see following dive information on main and alternative displays during Decompression mode:

  • TLBG;
  • O2BG (if any O2 accumulated during diving with Nitrox);
  • Tank pressure;
  • Deco stop icons and Deco Depth required;
  • Deco stop time required;
  • Total Ascent Time (time to surface);
  • Air Time Remaining;
  • current depth;
  • temperature;
  • time;
  • max depth;
  • Elapsed Dive Time (EDT);
  • PO2 current level;
  • FO2 set point;
  • applicable icons, etc.

 

Oceanic VT3: Diving In GAUGE Mode

If you use Oceanic VT3 as a Gauge - it would work as a depth gauge and timer only and wouldn’t perform calculations for nitrogen and oxygen exposure and moreover - following functions like Switching gases and Buddy Pressure Check are not available in Gauge Mode. In this mode VT 3 works only with Transmitter 1.

In Gauge mode you will get main and two alternative displays with the following information:

  • applicable icons;
  • Tank pressure;
  • Elapsed Dive Time (EDT);
  • current depth;
  • temperature;
  • time;
  • day of the week;
  • Air Time Remaining (ATR);
  • max depth reached

 

Oceanic VT3: FREEdiving

When you select Freedive mode Oceanic VT3 dive computer will operate as a depth gauge and perform nitrox loading calculations based on the default of FO2 of Air and the amount of nitrogen remaining between freedive and diving with Air or Nitrox previously (if any).

Freedive mode has set of specific alarms, which you set while on surface. They include:

  • Free Dive Elapsed Dive Time (EDT) Alarm – this alarm comes up every 30 seconds if set to ON.
  • Free Dive Depth (FDA) Alarms – you may set those to progressively deeper depths:
    • Depth Alarm 1 – range from 10 to 100 meters;
    • Depth Alarm 2 – range from 11 to 100 meters;
    • Depth Alarm 3 – range from 12 to 100 meters;
  • Countdown Timer – you may set it ON/OFF

 

During freedive you will get the main and alternative displays, freedive alarms displays, and if you entered into the Decompression mode during freedive – you will be given another display as well.

You may see following information on main and alternative displays:

  • graphic FREE;
  • TLBG (if any nitrogen still remaining from previous dives during last 24 hours);
  • Elapsed Dive Time (EDT);
  • Dive Time Remaining (DTR);
  • temperature;
  • current depth;
  • day of the week;
  • time

 

Also you may get easy access to Countdown Timer display and possibility to set it ON and OFF.

As I mentioned above, you may get into Decompression mode during freedive. This happens if nitrogen level increases to the Warning level. At this moment all segments on TLBG and O2BG will start flashing, Oceanic VT3 beeps on you, and message VIOLATION (VIOL) will appear. This is considered to be a Permanent Violation, you must ascend and do not dive for the next 24 hours.


Back to Top

 


 

 


 

 


 

After transition period you will have an access to:

  1. Dive Planner – plan and view your next dives according to the nitrogen loading or oxygen accumulation from your previous dives and surface time;
  2. Time to Fly countdown timer;
  3. Time to Desaturate countdown timer;
  4. Log mode with 24 recent dives (only air/nitrox/gauge; freedives not recorded to Log mode, they are stored in the memory and you may download them to your PC);
  5. History mode – contains accumulative information of you diving activities (freedives not recorded to History mode, they are stored in the memory and you may download them to your PC);
  6. PC upload/download function - interconnect Oceanic VT3 with your PC

 

It is worth to say here that battery removal doesn’t affect either Logbook data or History data and to keep nitrogen and oxygen calculations for repetitive dives you have to replace battery within 8 seconds – to make, so called, ‘hot swap’.

Positives

  • good size display - easy to read;
  • perfect not only for technical diving but can be recommended dive computer for recreational divers;
  • diver replaceable battery;
  • wireless system is very reliable;
  • great dive computer for the money

 

Negatives

  • poor battery housing design;

  • PC software is unreliable and needs a lot of work to improve

 

Having read all Pros, Cons, and comparisons with other computers, we may say that Oceanic VT3 has only small minor issues, and it is still a reliable dive computer that suitable not only for divers with experience, but for beginners who are serious about diving as well and who is willing to spend some time to learn documentation and more practice to get the most of this Oceanic computer!

Still have few complains about software, but overall it is a great dive computer designed for long-run and it covers wide variety of diving conditions.

And by the way, problems with software can be mainly due to not properly installed updated drivers and software itself; Oceanic stopped supporting outdated software and now has new versions for downloading and installation – check Oceanic website!

Oceanic VT3 - Great Dive Computer For Instructors And Advanced Divers

I'm PADI instructor and use Oceanic VT3 for controlling air pressure in my students' tanks. Works smoothly - just need to get closer to about 1 meter to pick up the signal. Other great functions - 4 dive modes and 3 gas mixes. User manual is not very user friendly - at least I had to spend few days to learn it properly, as I remember.

Display shows too much data, so some digits can be smaller. But its layout pretty well structured and easy to read - so I don't have guess work. Just quick glance to see what's happening.

I've been diving with Oceanic VT3 for quite a while and using all its functions on a fly. But if its you first dive computer or if you don't have much experience using them - set some time to learn it before even thinking going diving with it!

I Freedive With Oceanic VT3

I use VT3 not only for diving with scuba gear, but also for freediving. It works great - has all necessary alarms.

User manual was a nightmare at the beginning, but after few times reading it and really study it - I have no problems at all.

Not Even One Issue With My Oceanic VT3 With 520 Dives Logged

I have been using VT3 as my main dive computer since the middle of 2007. That time I wanted to have wireless reliable and multigas computer that gives me lots of functions in one package. I followed my mate's advice and got Oceanic VT3. I may say that I have never regretted about my decision.

At the very beginning - I was frustrated with user manual, but after becoming more familiar with it I appreciated what this little device might give you! And it gave me all the features I ever wanted!

It has good size display that is easy to read in any conditions and buttons are conveniently accessible.

To be honest, sometimes, my Oceanic VT3 loses wireless, but picks it up right away in few seconds, so I can say, that wireless is very good.

Very useful support for 3 transmitters and possibility to set VT3 for 3 different nitrox mixes, and swap gases is very easy and straightforward procedure.

I do not use freedive mode much, so can not comment on that.

My biggest and only one complaint - is a software, which is outdated and has few glitches. It does its job, but looks like guys from Oceanic created a great piece of scuba dive gear, but completely forgot to design PC program that is equal in quality with dive computer itself!
