Choosing a Dive Computer


Hi everyone,


Once you have completed your dive certificate and absolutely love the underwater world, getting your gear is generally next on the agenda and in this blog we are going to talk about dive computers and how to choose one from the hundreds of different styles out there in the market. We will compare different styles and brands and give some helpful information that will help you get a better idea of what you want in a computer.


Wrist or Console:


There are 2 styles of computers and they are a wrist and a console. The wrist is of course is a watch style that you wear on your arm as a normal watch and the console is a gauge like computer that is attached to a hose and is connected to your 1st stage in the HP port. They both do the same thing which is to tell you all you need to know when heading underwater including times, temperatures, depths, surface intervals, safety stops and more. The more you spend the more added extras you will get.

The watch is an independent piece of equipment and can be worn as an everyday watch (if compact enough). This can be used anywhere anytime as it is not connected to your regs, if you choose to travel but don’t want to take all of your gear, the watch is perfect. The only thing with a watch is that you have to remember it! Because it is not connected to your gear, you will need to remember to grab it when heading our for a dive.

The console style is connected to your gear so when you pick up your regs, you know for sure that you are taking your computer also. The console’s are the original style and many old school divers prefer these. They can be a little chunky sometimes, however now a days they are becoming more and more streamline.


Air Integration:


All console computers have air integration which will tell you your air yet only a selected few wrist computer will tell you your air. Air integration is when the computer reads the amount of air that you have in your tank so you know when to start ending your dive. To read the air amount, it needs to be connected to the 1st stage which is on the tank as the consoles are all connected to the 1st stage via the HP hose, they all tell you the air consumption. A watch style computer is of course not connected to your tank so to be able to read the air it needs to have the ability to wirelessly connect with a pod that is connected to the tank.




All dive computers whether wrist or console will have the basic features that include temperature, depth, safety stop and times as these are necessary for diving. Many dives prefer the basic models that only offer the minimal features, yet there are some divers who want more. As you being to start spending more on computers, more features will be available including gas mixes, air integration, digital compass, Nitrox and a back light as well as many more. Depending on your budget and need for information, will determine which computer you would choose. Here at Dive Warehouse we have a wide variety of computers from the basic models to the “fully loaded” everything but the kitchen sink models.


The Brands:


The brands that we carry here include Mares, Oceanic, Cressi, Hollis and Suunto. All of the brands we sell have basic to advanced computers and no brands is any better than the next, divers will generally choose their computer to go along with the brand of their gear, however there are no rules so you can choose your computer on features or look alone.


Happy Diving!
