how to choose your dive computer

Recommendations for choosing the right dive computer

(9)

Are you a regular diver (freediving, scuba) or are you into spearfishing? As you clock up your dives, you may well feel like having a better insight into your underwater adventures, your freediving or want to become more independent. In that case, a dive computer is a must.

But before falling in love with one of these amazing technological devices, take the time to read these explanations and recommendations intended to help you choose the computer that will be really useful both under and out of water!

 

DISCOVER THE DIFFERENT TYPES OF UNDERWATER DIVE COMPUTER

What’s the point of wearing an underwater computer? First of all, to keep informed all the time of your depth, your diving or freediving, possible stages to be made when ascending, your ascent speed, the water temperature, surface interval, etc.

Then, to help you analyse your diving once you’re out of the water, use the logbook which provides a record of all your dives!

 

 

CHOOSING A COMPUTER OR A COMPUTER WATCH?

Computer watches are a great hit! Small, mobile and usable daily thanks to their style, they are so sophisticated they’re now competing with standard dive computers. However, traditional dive computers stand out thanks to their better readability, in addition to being very user-friendly when diving.

Please note: if you’re long-sighted or wearing gloves this might pose a problem! The information is often written in small characters on computer watches and you need to learn how to press the buttons!

So, don’t hesitate to test your future computer watch in a Decathlon store. 

 

GO FOR AN UNDERWATER DIVING COMPUTER, A DEPTH GAUGE OR A FREEDRIVING COMPUTER?

And why not have all three at the same time? The majority of computers on the market include at least two modes - diving (air and Nitrox) and depth gauge – sometimes along with freediving/spearfishing modes or record/ simulator modes.

The depth gauge mode displays your depths and diving timed. It’s used with decompression tables to calculate stages.

The air or Nitrox mode provides, in addition, the information required for your ascent and your stages, and will be operational for a second diving integrating the previous parameters.

Freediving mode, available on the more complex dive computers or special watches, indicates (and records) your freediving times, your maximum and average depths, your recovery periods, etc.

To help you choose, carefully assess your requirements, your level and your current and future type of diving. Without forgetting, of course, your budget!

 

CHOOSING THE FEATURES OF YOUR DIVING COMPUTER

Distinguish the assets of the computers of apnea Tribord

 

Freediving computers have the same basic functionalities:

-        they are adapted to air dives and very often Nitrox (gas mixture made up of nitrogen and oxygen);

-        they are battery-operated; the battery can be replaced by the user or the After-Sales Service;

-        they have a simple depth gauge mode;

-        they come with a diving logbook;

-        they display: current and maximum depth, diving time, temperature, ascent speed with alarm in case you exceed the time, safety curve or depths/stage times curves.

 

Verify the legibility of the screen of its computer of dive Tribord

 

If you go up the range a little, the list of possibilities increases, sometimes too much for a recreational diver:

-        easy-read diving screen: colour, backlit and modular; 

-        possibility of hardening decompression and do deep stages;

-        wireless air management system indicates your consumption and the amount of air in your bottle before returning to the surface;

-        provision of a compass with recording of the headings: a precious tool in case of reduced visibility!

-        possibility of diving with several types of gas (as many as… eight!): Air, Nitrox up to 100 % oxygen and sometimes even with Trimix;

-        sound and/or visual alarms with adjustable settings:  maximum diving/depth time, ascent too quick, insufficient quantity of air, stages badly, or not, performed…

-        use of a large capacity logbook + PC transfer cable + dedicated software;

-        use of several decompression algorithms, a record mode with analysis, a simulation mode, etc.

Run through all your requirements to guarantee you choose the right product!

 

LOOKING AFTER YOUR UNDERWATER DIVE COMPUTER 

 

Before using the dive computer, you absolutely must read the instructions in order to clearly understand the underwater display of your dive computer and to be aware of its limits in terms of use and its emergency modes: your safety is at stake!

Likewise, this computer is personal and shouldn’t be lent to another diver between two sessions or during a diving trip lasting several days. This technological device, however well developed it is, shouldn’t, under any circumstances, be considered as a substitute for being trained or accompanied.

In the same way you look after your diving equipment, take care of your freediving computer on a daily basis starting with a five-minute desalting bath in fresh water, with the buttons being activated.

After that, dry it and put it in a protection cover designed for transporting it.

So, what will your next dive computer be?
