Dive Computer Selection: How Do You See Your Future Diving Career

Before investing any money, first you need to have clear vision about your future path as a scuba diver.

Sometimes I see guys, who have very expensive models with all of those features you may think about, but diving only once or twice a month with the long intervals between diving.
From my point of view – it is not a wise decision to buy expensive gear and let it have a rest, sitting somewhere in your locker, for the most time of the year (unless you have lots and lots of spare money and you don’t know what to do with it!) So, again, you need to think about your diving rate.

Also you need to plan of who you want to become in scuba diving: whether you will get certification only for Open Water Diver and stop, or you will progress until you will have Advanced Plus or Dive Master certification later on your path.

If you decide that Open Water Diver certification is enough for you – you, probably, do not need to select dive computer with plenty of features, which you will not even use! This way you will definitely save substantial amount of money! No doubt about that!

Dive Computer Selection: Your Preferable Mounting Option

This paragraph is about mounting options and we have 4 options available:

  1. computer consoles;
  2. dive watch computers;
  3. wrist units;
  4. units embedded in scuba mask


You need to decide clearly for yourself – what is the best option for you!

And it is a personal choice and the matter of convenience - you may imagine yourself wearing dive computer of certain configuration and how easy it will be using of that particularly model or you may go to the dive shop and try on different sample in reality!
It is up to you!

My opinion for this case – think convenience and how you feel by wearing the certain model, and also remember about activity you will be doing.
For example, if you want to do underwater photography - think about selecting following dive computer models: Aeris CompuMask HUD or Oceanic DataMask HUD. By getting one of them you will free your hands!


Dive Computer Selection: Your Desirable Specs & Functions

Here you need to imagine which features (be realistic, of course!) you want in dive computer.

These days dive computers are little sophisticated beauties, packed with many – many features, like:

  1. few dive modes;
  2. some of them have Dual Algorithm for liberal and conservative settings;
  3. possibility of programming for 3 or more different gas mixes;
  4. wireless air – integration;
  5. monitoring your heart rate;
  6. adjustable settings of Personal Conservative Factor, Altitude, Deep and Safe stops;
  7. colour display;
  8. PC interface;
  9. dive simulator;
  10. digital compass;
  11. possibility of downloading from PC colour or grey – scale pictures and maps into the unit;
  12. user replaceable batteries (you should definitely look for the model with this option, but many of them these days have this option anyway), etc.


And, do remember, that doing dive computer selection and picking up one with extra features may add quite a few bucks to the starting point! So, please, make a list of options and features you want to have!

Dive Computer Selection: How It Will Emphasize Your Personality

This step is all about how your selected scuba dive computer will give the best fit to your personality and emphasize it! It is pure individual matter.

If you do not care about it – skip this step!

I spoke to quite a few people around and I found out that many people wanted to wear a unit that would emphasize somehow their personality! They wanted to have a model, which was “made especially for her/him”!

Some of guys even made up funny names for their little electronic devices!

I will leave this option open for you!

If you like pink Suunto D4 more than yellow Oceanic GEO – go for it! Just make sure that model of the colour of your preference has all desirable features!
At least after you selected dive computer you would not regret about your choice later and make your diving experience even more enjoyable by having your little electronic underwater friend with you!


Dive Computer Selection: What Is Your Budget?

It is money time! This is probably the most important step.

I assume here that you do not want your family suffer financially because of your investment! So, choose dive computer wisely!

After you made a list of your diving career path, mounting option that is best suits you, list of features of the dive computer – you have come up with few certain models from our collection.
After some fine tuning and choosing dive computer that will be a “special one”, you may notice that your leather wallet is a little bit thin for that particular model. Do not worry! Just look realistically again…

Maybe you do just fine by having dive computer without wireless air – integration, freedive mode and integrated digital compass right now, and will go perfectly with simplier models, like Mares Puck, Cressi Archimede 2, Suunto Zoop or Tusa IQ-650 Element!

But if your wallet is thick enough and you are planning to proceed with your diving career rapidly and go for technical diving, you may want to select more expensive dive computers, like Aeris Atmos Ai, Aeris Elite T3, Mares Icon HD, Oceanic OC1, Suunto D9 and Suunto HelO2, Tusa IQ-850 DC Sapience II, and UWATEC Galileo SOL with capabilities of wireless air-integration, multi – gas options, possibility of heart rate monitoring, uploading pictures, digital compass and much more.


Dive Computer Selection: Few Words About Buying Dive Computers From eBay

My personal choice – I wouldn't buy used dive computer from private seller on eBay! I still may consider buying some other dive gear and accessories after good checking reputation of the seller, like I did few times already.

Prices might be lower than from the authorized retailer, seller is obviously sincere, and reviews could be excellent, but I met few different guys in 2010, who bought from eBay their stuff and during diving those computers failed by displaying dive data that was way very different from the real! And all ended not very nicely!
And at the same time I know quite a lot of people who always buy from eBay and they are perfectly OK with this option and theirs dive computers serve them well! It is totally up to you!

So, if you desperate to buy from eBay or any used unit and bought it – make sure that your chosen dive computer have been rigorously checked by an authorized technician or request a requirements compliance and certificate of compliance with all tests!


Dive Computer Selection: Few more words about dive computers without audio alarms and backlight for newbies

It is only my personal opinion about this matter.

If you just started diving and are comfortable with dive computer that doesn’t have audio alarms and backlight – that’s totally perfect! Here are few examples of models without audio – Oceanic Veo 1.0, Veo 100 NX, Aeris XR-1 NX, Tusa IQ-650 Element – just for your attention!

But I think if you are a beginner – you need to buy model that has audio alarms and warnings, and backlight – it won’t cost you too much! Because audio helps you stay aware of situation you are in – it grabs your attention.

You may concentrate on enjoying diving and not goggling at your computer all the time, waiting when display will change and show you time for Deep or Safety stop or something else.

And beginners do not have that experience yet, which mature divers have, beginners do not know what to expect and when! So, if you are at the beginning of the diving career – select dive computer that has audio and backlight!
