Buying Guide

When it comes to finding the best dive computer for beginners, there are some things to take into account before you jump in and buy one.


This is a big one. There is no point in investing in a dive computer that is not compatible with your current diving equipment. In addition to the diving equipment, it also needs to work with the computer you have.

If you have a MAC and you end up with a dive computer that is only compatible with Window products, you’ve either got to replace your new dive computer or your desktop or laptop computer.

Always check to see if the piece of equipment you’re buying is going to work with your current setup, that way you can evaluate your options and see if you want to make any changes to accommodate for the dive computer or if you’re going to go with a different dive device.

Screen and Display

All computers are different, meaning you’ll be running into a lot of different styles of display. The screen of your dive computer is where all of the data will be displayed, such as your air time, how long you’ve been underwater, and several other things, depending on the computer.

Some of them have a segmented display, making it easier to differentiate between different values. Always take a look at photos of the display screen before buying a dive computer so you know if you’re going to get something you can understand or not.

Another thing to think about when it comes to the screen and display is if there is any sort of lighting. This is important because some dive computers can be used as watches so being able to see at night is important.

You also want to be sure you’ll be able to see when you’re underwater, since the further down you go, the darker it gets.

Air Integration

This is a really great detail to be able to keep track of since it could end up becoming a matter of life or death. The air integration is a setting that basically means your dive computer can keep track of how much air you have left.

Keeping this information on hand allows your computer to calculate your breathing rate, informing you of the estimated time left based on your current air consumption, and can readjust estimates if there are any changes to your breathing.


Finding the best dive computer for beginners that has alarms is very beneficial for a few reasons.

The first is that many computers have both audible and visible alarms, letting you know when you get close to a limit, often pertaining to the amount of air you have left. Some of the variations in the alarms can be a flashing backlight and a beeping noise.

Other alarms include letting you know when you’ve been underwater for a certain amount of time, tank pressure, and when you’re low on gas.


Here are some frequently asked questions about dive computers for beginners.

What is a dive computer?

A dive computer is a small piece of technology that was designed to keep a diver informed of various stats, as well as often keeping track of their dives for later reflection.

Many divers start off with a wrist watch style dive computer since they are typically easy to use, lightweight, and offer multiple functions, such as being able to be used as a watch when not being used for diving purposes.

Dive computers can keep track of your air, your heart rate, breathing patterns, and how long you have been underwater.

They can also inform you of when you have been underwater for a certain amount of time, when your air levels are low, and if you are at risk of anything else they can detect.

If you are new to diving, it is definitely a great idea to get into the practice of using a dive computer because they are fairly affordable and being able to ensure you will be safe is priceless.

Are there other styles of dive computers aside from the watch?

There are several different styles of dive computers. The watch style is very popular because it is simply strapped to your wrist and easy to see without needing to have a free hand.

Other styles of dive computer include:

  • Dive Console Computer: This style looks like the traditional gauge console that contained a compass, depth gauge, and analog pressure. The newly revamped version has a digital display and shows all of the dive data, plus a compass and tank pressure.
  • Dive Wrist Computer: This style is similar to the watch in the sense that it lives on your arm when diving but that’s about where the similarities end. These compact computers have large screens with easy-read letters and numbers. All of the dive info is on display on the big screen.
  • Hands Free Dive Computer: If you’re looking for something high-tech that feels like it’s out of your favorite spy movie, this style would be a great choice. It is mounted on your mask and has a floating display that utilizes near-eye optics. What does that mean? The information stays displayed in front of you so you can keep track of all the stats you need.

What is the best style of dive computer?

As with most things, what is best for one person won’t be best for everyone. This is true for dive computers and pretty much everything in life. When you think of a dive computer, what style sounds like it would be the best fit for you?

If you want to have something that is affordable, easy to use, and won’t take up a ton of space, a watch style computer would be a great choice. If you want something you can look at when needed but isn’t always in your face, the dive console computer may be the right one for you.

If you want to feel like you’re in a video game with your stats on display, then you would probably like the hands free dive computer.
