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. air integrated dive computer

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!
