How to Choose a Scuba Diving Computer

When it comes to choosing a dive computer, you need to consider several factors. Here I will run through some of those factors and how those factors will affect your driving. Firstly the most important factor when it comes to choosing a dive computer is the color, and the size of the computer as everyone knows that Scuba Divers are a vein lot and like to show off with big watches and brightly colored gear – JUST JOKING – (divers have a sense of humor too!)


Right onto the real factors.

It would help if you first decided whether you want a console-mounted computer or a wrist-mounted Dive Computer. Some Dive Computers come with a wrist band but can actually be taken out of the wrist band and placed into a console so you can change the arrangement at a later date; however, many computers don’t, so you have to make the decision when you purchase the computer. So let’s run through some pros and cons of a wrist-mounted Dive Computer.

It is a personal choice and can often be decided by what you use as a recreational diver. If you are hiring equipment, you will most likely get used to the setup and configuration of the hire equipment and, therefore, will make your decision based on that. However, I strongly urge you to consider what type of diving you plan on doing before making your choice. What I mean by that is, are you going to remain a pleasure dive taking easy fun dives just for leisure, or do you plan on becoming a dive professional or a technical diver? Depending on that type of diving you plan on doing should help you decide on what type of Dive Computer you will choose.

As a Dive Professional, I personally prefer a wrist-mounted computer as I generally need my hands to be free to assist student divers. In the case that I have a diver panic, I need to be able to control that diver and obviously help control their assent if they are trying to make their way to the surface. By having a wrist-mounted computer, I can hold onto the student and keep my computer at eye level to ensure we are not making a rapid ascent. If I had a console-mounted computer on hand would be tied, upholding my console up to eye level.


If you plan on doing technical or deep diving that will require deco stops, or if you find yourself in tight crevices, caves, or swim-throughs, I personally think it better to have a wrist-mounted computer, again for the fact that while you are holding your deco line, you have your Dive Computer at eye level, so it just takes a glance to check your depth and time rather than having to hold the deco line and the console. Also, while in tight areas, you may not reach your console, whereas a wrist-mounted computer will be at hand always.

If you don’t plan on becoming a Dive Professional or a Technical Diver, then a console-mounted Dive Computer may be a better choice. Generally, in pleasant recreational diving, your dive computer is merely going to be used as a timing device to work out your tables to keep you safe from staying down too long; you are not going to need to check your computer while making rapid ascents continually or at great depths. For this reason, it is in your console, out of your way, and is there for you to check on it every so often during your dive just as you do your air. The other advantage of having a computer on your console is that it will always be a part of your dive gear, so when you pack for a dive, you know that if you have your regulator set up in your dive bag, then your computer is there too unlike a wrist-mounted computer which could be easily left at home when you go diving. So again, for recreational purposes, a console-mounted diver computer makes a lot of sense.

Also, as you most likely won’t be handling panicked divers or decompression stops, you will not need to monitor your dive computer on every ascent as you become used to making a slow ascent yourself. These are the 2 main factors you need to consider. However, as I mentioned before, you must plan for the future and consider if you plan on diving with Nitrox, then you will need a Nitrox compatible computer to keep you safe on your dives. You can also get air-integrated dive computers that will keep track of your air as well as your depth and times, so doing away with one extra Dive Gauge on your console. You would choose a computer like this if you want to streamline your dive equipment and you are comfortable using computer-based technology to monitor your air supply while on a dive.

If you are really interested in streamlining your Dive Equipment, then you can get air-integrated hoseless wrist-mounted Dive Computers that have a transmitter attached to your first stage regulator instead of a hose allowing you to do away with any Dive Gauge Console completely. Again you must be comfortable using technology to monitor your air supply – this time without a hose. These computers are a great way of streamlining your equipment, as we all know how bulky your dive gear can be.


Aside from all the above, you have to think about functionality and features such as if the computer has a light, has audio alarms, can it be downloaded onto a computer if you like to log your dives online.
