From beginners exploring tropical reefs to seasoned professionals undertaking technical dives, a dive computer offers real-time data that keeps divers safe, and informed. But how do you know if it’s time to invest in one? And with so many options available, how do you choose the right model?
Here we go over the key points you will want to keep in mind when selecting your dive computer. What you need to consider will depend on where you are in your dive journey, and your preferences. For beginnings you may not have many preference, but for tech divers and other professionals, having some added bells and whistles to your dive computer may make all the difference.
Should You Invest in a Dive Computer?
A dive computer tracks essential metrics such as depth, dive time, and decompression limits, giving you real-time insights that can be lifesaving. One of the most important tools in regards to divers safety, is your dive computer. So although it might not be your very first purchase, getting one should come relatively early in a diver’s evolution.Â
For occasional divers, renting a dive computer might seem sufficient. However, owning your own device allows you to familiarize yourself with its interface, making it easier to use during dives. Frequent divers or those progressing to advanced certifications will find that having a personal dive computer is indispensable for tracking dives and enhancing safety.
DAN, a leading authority in dive safety, emphasizes the importance of tools and practices that enhance diver safety. Dive computers play a key role in this, helping divers better manage their profiles and minimize decompression risks (as long as it is used correctly).

How to Choose a Dive Computer?
Choosing the right dive computer involves considering your diving habits, budget, and future goals. Here’s a breakdown of key factors:
- Frequency of Diving:
- Casual Divers: Entry-level dive computers are affordable and provide all the basics, including nitrox compatibility.
- Frequent Divers: A mid-range option with a more durable build and advanced features may be better.
- Air Integration:
Do you want a dive computer that connects wirelessly to your regulator? This feature, while pricier, provides integrated air data and adds convenience for divers using their own gear. It may also be something only a professional or very experienced diver wants to invest in. - Algorithm Customization:
Dive computers use decompression algorithms to calculate dive limits. Why no decompression model will guarantee safety, you may want to consider how your dive computer calculates your dive time. Do you want or need the ability to change these settings based on your preferences? Please note: never change any settings on your dive computer unless you have been trained to do so, and understand the implications of making such changes. For most rec divers and professionals any dive computer, when followed correctly, will minimize the chance of decompression sickness. - Advanced Considerations:
Do you have the need for your device to handle multiple gas mixes or even closed-circuit rebreather (CCR) dives? If so, this is something you will want to look into when purchasing. - Service and Care: It’s going to be beneficial to find out what kind of warranty or care you will want to have included in your purchase. If something goes wrong with your dive computer will you be able to take it to the manufacturer to have it fixed?
- Frequency of Diving:
Non-Diving Functionality of Your Dive Computer
Today’s high-end dive computers go beyond underwater use, and they have so many more functions than just those diving related.Â
- Fitness Tracking: Monitor your activity levels when you’re not diving.
- Smartwatch Functions: Receive phone notifications, track sleep, and even set alarms.
- Durability and Design: Some models double as sleek wristwatches, allowing you to wear them daily without needing separate dive-only gear.
While these extras are great bonuses, they come at a premium. It’s good to know what additional options are out there, but you should take time to evaluate whether these features align with your lifestyle.Â
