Scuba Dive Computer:

|
A scuba dive computer is a fantastic piece of scuba gear and can come in several different types and styles. Which one works best for you is a personal preference - as is what information you want the dive computer to generate.
The different types/styles of dive computers are not mutually exclusive. For instance, you can get a wrist mounted dive computer that is air integrated.
So it's like a menu, pick the features that appeal to you and get the best scuba dive computer to meet your needs.
Here is a list of the different types and/or styles you can choose from:
(Also take a look at our scuba diving computer guide for more information.)
Wrist Dive Computer
The wrist dive computer is very popular. These types of computers look like large watches and are worn on the wrist (obviously, hence the name).
They will tell you all you need to know at a glance. People sometimes use their dive computer watches as everyday wrist watches. Some wrist dive computers are also able to be mounted in a console (see below). 
Sometimes the faces may be a bit small for all the information the computer can display, so make sure you will be able to read it underwater.
Some wrist dive computers are rectangular in shape, giving you a larger display area and easier to read numbers. This would probably be your best bet if you want a wrist mount and have trouble reading smaller numbers.
Unless they are air integrated and wireless (see below) wrist scuba dive computers usually do not come with a pressure gauge.
One small disadvantage here is that these can be pretty easy to misplace/lose. Since this can be a sizeable investment, you want to keep track of this piece of scuba equipment.
Console Dive Computer
A console dive computer is attached to the rest of the equipment via a hose.
The console dive computers typically come with a pressure gauge, unlike the wrist mounted option. The readouts are typically larger than on a wrist dive computer so they can also be easier on the eyes.
There are also options for a scuba dive computer to be mounted on your hose (this is the type we currently use) or clip onto your BC.
Choose whichever is more comfortable for you and fits into your price range. Other factors you need to consider when choosing a dive computer are:
Nitrox Dive Computer or Not?
With nitrox diving becoming more and more common, so are computers that are nitrox compatible.
Even if you aren't diving with nitrox now, if you are even thinking of diving with nitrox in the future, it is probably worth it to purchase a nitrox dive computer. This will save you the expense of buying a whole new computer in the future.
However, if don't think you will ever dive with nitrox, then there is no reason to pay for this feature. A standard air computer is probably $100+ less than its nitrox counterpart.
All dive computers can dive with standard compressed air, but not all dive computers can dive with nitrox. Nitrox dive computers allow you to program the percentage of oxygen in your mix (standard compressed air is 21% oxygen).
A nitrox dive computer shows all the same information as air computers so it's ability to program various gas mixtures is it's distinguishing feature.
Air Integrated Dive Computer or Not?
Air integrated dive computers are becoming more commonplace. An air integrated computer measures the tank pressure (in addition to all the other information mentioned here) and then calculates how much more time you have left at the current rate of air consumpetion.
So if you are chasing that beautiful fish and you are running out of time, you might want to slow down and extend your dive. The air integrated dive computer will tell you how much time you can spend at any exertion level.
An air integrated scuba dive computer replaces the need for a submersible pressure gauge (SPG). One downside of an air integrated dive computer is that if it fails, you lose information on how much air you have left in your tank. Dive over.
Hoseless Dive Computer or Not?
When we get to the hoseless scuba dive computer, we are talking some real money here.
The hoseless dive computer consists of the receiver (typically worn on the wrist or mounted on the BC) and a transmitor. The transmitor attaches to the high pressure port of the scuba regulator first stage and then sends your air information, wirelessly, to the receiver. The receiver looks the same as normal dive computers.
This setup cuts down on the number of hoses you need. There are now even hoseless dive computers that can accept signal from muliple transmitors - so you can even keep an eye on your buddies air consumption. Of course, this capability is really for the more advanced technical divers who may use different tanks on one dive.
There is no right or wrong scuba dive computer. You just need to pick one that suits your needs and your are most comfortable with. Not to mention one that suits your pocketbook!
