Best Dive Computer Reviews

1. Suunto EON Steel Dive Computer

Our Review Score

The first on our list is arguably one of the most sophisticated diving computer systems on the market right now. The Suunto EON Steel Dive Computer features a large and clear colorful screen that doesn’t just display dry and boring numbers but models and graphs too. This is perfect when you want to just quickly check how well your dive is going without having to spend longer than a few minutes deciphering the meaning of various numbers.

The three main buttons on this wrist computer are reasonably big and spaced out enough that they are easy to press even when you are wearing thick gloves, giving the ease of mind and confidence you need when you are deep under the water. As this is a larger unit than a lot of others, it means that it uses a larger battery.

With a comfortably large and adjustable strap, you can always be sure that the computer will stay securely on your wrist and provide you with access to the data related to your dive that you really need at all times. Along with the incredibly colourful and bright screen, we would recommend this dive computer because of the easy to press buttons, adjustable strap and the fact that it features trimix and rebreather capabilities that mean even if they are useful to you in the beginning, you’ll have that kind of functionality when necessary without having to upgrade to a different model.

2. Cressi Newton Titanium Dive Computer Watch

Our Review Score

The Cressi Newton Titanium Dive Computer Watch has an incredibly small case diameter of 48mm, making it one of the most compact of its kind. Don’t be put off its small build though, because it has enough features to make it a superb companion on all your dives. Its Dive programme, for instance, offers full processing of all dive information, including decompression when required and works with all dives performed with just air or nitrox.

On this model, a new algorithm has been utilized. The Dual Mixture Cressi Algorithm is the work of Bruce Wienke and Cressi and takes the Haldane model and integrates that with RGBM factors to make safe and accurate decompression calculations during repetitive dives over multiple days.

The Cressi Newton Titanium also makes use of a tissues model with 9 saturation half-times between 2.5 and 480 minutes. It also has a nice and clear Graphic CNS oxygen toxicity display and includes a log book with a capacity of either 60 dives or 70 hours. The fact that you can turn the Dive programme off and wear this watch while you snorkel, swim or do things on dry land without using too much battery, really set it apart. Overall, as this watch fulfills its role as a dive computer and an everyday watch, we recommend this for anyone looking for a feature-filled, but budget dive computer.

What to Consider when Buying a Dive Computer

Now that you know what our top picks for the best dive computers available on the market right now are, it’s worth discussing some things that are worth considering if you are buying one.

First things first…

Why Should You Use a Dive Computer Instead of a Dive Tables?

You may wonder why you should bother investing a considerable amount of money when people are still happily diving and using dive tables to work out the information regarding their dives. Although these tables are useful for calculating the recommended duration you should spend underwater, the surface interval time and Nitrogen levels, technology has advanced a lot over the last few decades and there are now more accurate ways to calculate all that important data related to dives.

Furthermore, as dive tables were not created with the recreational diver in mind, they were designed as a resource for Naval officers and calculate the crucial numbers for very specific dive. They do not, therefore, work as well to help recreational divers who don’t want to just dive down to a specific point and then ascend again. Dive computers are ideal though, for those who like to descend and then dive further down or up a little while hunting for wrecks, fish and coral. Although dive tables can help avoid decompression sickness or ‘the bends’, they are still not accurate enough when compared to even entry-level dive computers.

How to Choose the Right Dive Computer

The first thing you need to think about is the level of diving experience you have, now that you’ve decided you do want to buy a dive computer and are not sure which is best from our selection. This is why we noted in the opening paragraphs that it’s less about buying what your friends have or the most comprehensive system, and more about buying exactly what you need for your ability and experience.

Beginners – We would recommend that if you are a complete beginner, that you get a scuba diving computer that is relatively simple, easy to use and has a large display. When you first start diving, you’ll find that a lot of your time is spent getting comfortable swimming and breathing underwater and you won’t want to be fiddling around with a high-tech piece of kit.

Advanced Technical and Recreational Divers – Obviously it follows that your needs are different to that of a beginner if you are more advanced. Having additional features such as trimix capabilities are crucial and you will want a computer that can handle deeper dives too.

Must-Have for Dive Watches and Computers

Easy to Read

Regardless of what level of experience and ability you have as a diver, your dive computer display should be very easy to read. Therefore, backlit displays, high contrast and large numbers are what you should look out for.

Easy and Intuitive to Use

Not all dive computers are made equally, and as such, some are much easier to use than others. To avoid spending half your time underwater fiddling with your dive computer, this is one aspect you should consider very carefully. Many modern computers have very intuitive user interfaces. You also need to consider the type of water you will be diving in. If you are mostly diving in cold water rather than hot water, remember that you will be wearing warm and thick gloves. A dive computer with bigger buttons would obviously make more sense in that kind of scenario.

Budget

Although we stated in the opening paragraphs of this post that you shouldn’t base your buying decision solely on budget, it is something you will need to take into consideration along with everything else we’ve discussed. For a basic dive computer, you should expect to pay anything from £100 to £300 and for one jam-packed with features it could be anything from £500 to £1,000. Fortunately, if diving is a relatively new pastime and you don’t have a huge budget to play around with, there’s still numerous entry-level dive computers made by reputable brands that include the most essential modern features. Many of these are actually listed in our top 10.

Set-up and Style

Generally speaking, there are two different types of dive computer setups – console and wrist. All of the computers featured on our list are the wrist variety.

Wrist computers enable you to have access to all the crucial data about your dive right there on your arm. The most obvious advantage of this style over a clunky console, is the fact that they are slicker, more streamlined and much easier to read. You should note that there are two different kinds of wrist dive computers, the one that looks like a hockey puck has been strapped to your arm and the one that resembles a watch.

Wireless Air Integration

Incredibly popular nowadays, wireless air integration is a fairly self-explanatory function you will find on many modern dive computers. It means you can basically monitor the air and gas consumption through your dive computer via a transmitter, rather than having to check the gauge on your tanks. You need to realize though, that as good as wireless air integration technology is, you should not dive without your SPG. In a worst-case scenario, what are you going to do if you are over 100ft below the water surface and lose the signal from your transmitter to your watch? You’d have no way of knowing how much air you have left in the tank, without your SPG as a back-up. Safety should always be your primary concern.

Now that you have looked at our reviews and read our tips and advice, you should now find it much easier to choose the best dive computer for your needs, but remember, once you have your piece of scuba equipment, you’ll need to know just how to care for your dive computer to make sure you get the most out of it. Happy Diving!
