What to consider when buying your first dive computer

We get it. You really want your dive computer to look as cool as possible. But when you’re new to scuba diving it’s much more important that you find your new dive computer easy to use.

And when you’re just starting out you might not want to splurge on the fanciest model out there.

So here’s our list of the top things to consider when buying your first dive computer.

How easy is the dive computer to use

The best dive computers for beginners are the ones that are easiest to use. Bear in mind that a complicated dive computer will distract you more than it helps you underwater.

So you want to choose an intuitively designed model with easy to navigate menus for planning, tracking and logging your dive.

As a newly certified scuba diver or even a more experienced recreational diver, you won’t really need all those additional features.

And what’s more is that a great beginner dive computer becomes the perfect backup computer if you do decide to upgrade in the future.

style of dive computer

Dive computers come in 3 different styles; a traditional console computer mounted with your pressure gauge, a wrist-mounted dive computer and a dive watch computer. The wrist-mounted dive computer is the best style for beginners.

A wrist-mounted dive computer is a little bulkier than the smaller watch computers but they are much to set before your dive and easier to read during your dive.

They’re easier to check than a console computer and also tend to be much more durable and long-lasting than a dive watch.

Screen size & brightness 

When you first start scuba diving there’s a lot to remember when you’re underwater and keeping an eye on your dive computer can be a little challenging.

So you want to make sure you can quickly and easily read the information displayed on the computer.

If you plan to often dive in low visibility or you just don’t see well close up then you want to choose a dive computer with an oversized and backlit display.

Or if you are leaning towards a smaller model, make sure it has a bright screen that’ll be easy to read even at depth.

Durability and longevity

Although dive computers are much more affordable nowadays, they’re still a significant investment for a beginner. So you want to choose a computer that will last you a long time.

If you plan to dive often, or you know you can be a little hard on your dive gear, choose a robust model that’s really built to last.

And don’t forget to check out the warranty on your chosen dive computer before purchasing!

The type of scuba diving you plan to do

Be sure to choose a dive computer that is suitable for the type of diving you plan to do.

For example, if you’re a certified enriched air nitrox diver, or plan to become one, you want to make sure you choose a dive computer with a nitrox setting.

Or if you’d also like to use your dive computer for freediving, make sure that it has a freediving mode.

Your budget

When it comes to dive computers, more expensive doesn’t necessarily mean better. There are as many excellent, and safe, dive computers at the lower price points as there are at the higher end of the scale.

The best dive computer for you should be easy to use, long-lasting and, of course, fit your budget


Frequently Asked Questions

Do I really need a dive computer?

A dive computer is rarely mandatory. But most scuba divers consider their dive computer an essential part of their dive gear. And we ScubaOtters never dive without one.
Yes, you could use the dive tables (if you can remember how to use them) along with a depth gauge and bottom timer to stay within your limits.

But a dive computer will do all the hard work for you. And much more precisely. By tracking your dive profile in realtime, it gives you the longest possible bottom time.

A dive computer will also track your safety stop, ascent rate, any emergency decompression stops and much more.

Simply put, a dive computer gives you all the information you need to dive safely.

Now you might be thinking ‘can’t I just follow my guide’s dive computer?

You could. But your guide’s dive computer does not keep track of your dive profile or take into account any nitrogen load from your previous dives.

The computer is tracking their safety and their no-decompression limits, not yours. So if you want to be fully in control of your own safety it’s much better to have your own dive computer.

And if that’s not enough, more and more dive centers and liveaboards are now requiring all divers to have their own dive computer. Which means if you don’t own a dive computer, you’ll be forced to rent one.

This will quickly add up over a week or two of diving. So it’s smart to invest in your own dive computer. As one of the smallest and lightest pieces of dive equipment it’s super easy to travel with.

What is the easiest dive computer to use?

The easiest dive computer to use is one that you can easily understand how to operate and can clearly read the display during a dive. As with any new piece of gear it will take a little time and practice to feel comfortable with a dive computer.

All of the dive computers we’ve listed above are intuitively designed for recreational divers so they’re relatively easy to use. However as the majority of dive centers teach using the Suunto Zoop, or similar, many divers find this dive computer the easiest to use.

How long do dive computers last?

As long as you look after it properly, a dive computer will last for several years, if not longer. But depending on how often you dive, you will need to replace the battery at some point.

How much does a dive computer cost? 

You can expect to pay anywhere from $200 up to $1,500, or even more, for a dive computer.

As with all pieces of dive equipment, there is a big range in price across different brands, styles and models.

Nowadays all modern dive computers, even the cheaper models, have all the essential features you need to stay safe.

The more expensive dive computers tend to be sleeker in design and have additional features such as a compass, options for different gas mixes and ability to read the pressure left in your tank.

Check out our guide to air integrated dive computers for more information.


As a new scuba diver, a dive computer really is one of the best investments you can make.

Not only will a good dive computer help you stay safe on every dive, it’ll also keep track of all your diving adventures and will easily last you for many years to come.

And if you pick from the list above you can be confident that you’ve got one of the best dive computers for beginners.
