What is a Dive Computer?


Being able to track your dive is a crucial aspect of staying safe. A dive computer will have all your data available in a small compact setup. Knowing things like how long you have been underwater and your diving depth will allow you to plan your route and alter your breathing accordingly. These little computers can actually save your life.

High quality computers can alert you of a fast descent or ascent which can cause dizziness or even the bends. This happens when you ascend to quickly which cause air bubbles to form in your body which can be fatal. There are many features that these little pieces of technology provide that can make your dive more enjoyable.

What is your level of diving?

Different levels of divers will need different dive computers. Beginners to the sport may not need fancy features that more advanced divers need. The most important thing beginners should look for is a large easily readable screen and has an easy to use interface. This will ensure you will not run into trouble while under the water. More advanced divers should look for advanced features relating to decompression and a more advanced interface.

Things to look for in the best dive computer

There are many things you need to have in your dive computer. This is one of the main pieces of gear that can help you through every step of your dive. Dive computer reviews agree that the following are the most important things to consider before making your purchase.

Ease of use

Even if the dive computer has the latest technology and a crystal clear LCD screen if it is not easy to use it is not worth the money. Being able to navigate through the menus with gloves on is a key aspect you should consider when buying a dive computer. Large, space out buttons will make your trip underwater easier and instill confidence in your equipment.

We recommend spending time learning your system before entering the water. This will save you time, energy and confusion while on your dive. We suggest reading the reviews of the product on the lookout for how easy the computer is to learn.


There is no point in spending the money on a dive computer if you are not able to read the screen with your mask on. It is highly recommended to find a computer that has a multi colored or bright screen that allows you to easily see the readouts. A dark text color on a light background also creates enough contrast to see the critical writing. Not having to shine a light on your screen will save you a step and allow you to spend your time on other things. It is also important to get one with a large enough display to easily read.


A few gauges you can live without but depth, how much air you have left and time under water are ones that you cannot. Being kept updated in real time about your dive is critical for not only safety but peace of mind. Knowing how much air and battery you have left is not something that can not be accurate as it could affect every aspect of your dive.

Some dive computers will help you with your decompression time. They will have specially designed algorithms that factor in the depth and decent time which will output how long your ascent should be. If you are traveling too fast they can even tell you to stop and hold your depth while your body gets accustomed to the change in altitude.


Being able to easily see your computer is a key aspect to consider when looking to purchase a dive computer. Many are worn on your wrist while some attach to your suit. Being able to simply turn your wrist and have all your information available to you is a sought after feature. While others like their stats more out of the way allowing their arms to be free from added weight. This is personal preference but should be thought out for your next dive.


One way to tell the quality of your scuba gear is by the warranty. All dive computers will come with a one year warranty while well made ones will come with up to a two year. Longer warranties indicate higher materials used to make the product. Look for dive computers that have a two year warranty whenever possible.


Dive computers can cost anywhere from $199 to upwards of $1700. If you are just entering the sport of diving you may not need a fully equipped dive computer. Finding one that has the gauges and specs you need is key. Sacrificing high tech features can save you some money but may be missed when you develop more experience. Color screens will also increase price and are not always necessary.


Being able to connect your dive watch to your computer will allow you to compare your dives over time. This will show you how you are progressing and stats you never thought of during your dive. You will be able to see everything from the depths you travel to your time underwater. This shouldn’t make or break your decision but is a nice feature to have at the end of the day.

Most computers come with memory logs built into the device. This may be measured by time in use or number of dives but is a nice feature to have when tracking your diving progress. It allows you to save your dives and compare them with each other.
