How to Choose Your Computer

Yet again the brand of the computer is not that important as many come from the same designers and factories.

Not only that ….. they all do the same thing and do it well. There are very few real differences between the features.

Standard or Air integrated

The air integrated (either with a transmitter or on a console) computer measures your cylinder pressure and computes your air consumption.  This is not an essential feature and it unfortunately doubles the price of the unit. So if you are rich…. Get one….

For the rest of us we go for the standard version.

The 3 Options:

Option 1…. is to have the computer on your console. The advantage is that it makes it much cheaper if you are buying when you buy your regulator as it saves the cost of gauges. In addition you won’t forget the computer before a dive as it is always on your set. The downside… it is more prone to damage.

Option 2 A wrist mounted large computer. This is the most cost effective option.  Its large screen makes it easy to read and simple to operate.

Option 3 A watch style computer. These are great if you are going to wear them as a dress watch in normal day to day life or even just when on a dive trip. They are however twice the price of the normal large computers. The choice should depend on which one tickles your fancy looks wise.


Most need to be taken in to have the batteries changed and then the computer is tested in a chamber. User replaceable batteries are a great feature.
