Scuba diving is gaining immense popularity as an aquatic sport, especially in countries such as the U.S., the U.K., and other European nations. Manometer for pressure measurement, a timer for oxygen timing, and a depth gauge are necessary tools for a dive. The wristwatch dive computer helps record the time, maintains the dive time at a certain depth and helps monitor the overall dive time.
The dive computer is considered to be the most necessary diving tool. Hence, dive computer manufacturers are introducing portable computers such as a wristwatch. These computers are typically compared to a square console or a small watch. They also help keep track of the depth while diving, which can cause compression sickness in divers if ignored.
Divers can be safe from any possible danger from prolonged exposure to compression in water and higher nitrogen levels while diving. Each dive is automatically timed, and the depth is measured by the gadget, which then uses the information that divers can use for future references and create a diver profile. Additionally, depth measurement and timer have eliminated the depth gauge and time watch.
Scuba diving is considered an essential marine tourism sector because of the growing demand for diving activities. To enjoy these activities and reduce the hazard while diving, divers require dive gadgets and safety equipment such as dive computers which help divers in various ways. Numerous professional divers strictly use different diving gadgets and safety equipment to make diving activities possible, accessible, safer and more comfortable. Scuba diving instructors and schools suggest diving gadgets such as dive computers to use while diving to reduce risk and maintain personal safety.

Released in November 2020, the Garmin Descent Mk2i is the dive computer of the future.
Though Garmin are relative newbies in the diving world, they have launched themselves onto the scene with a bang by creating some of the best computers on the market.
The Mk2i builds on the success of the Garmin Descent Mk2 and takes on board all the feedback from expert divers. The air integration offered by the Mk2i is cutting edge.
Whilst most computers use a traditional VHF radio frequency to pair the computer and transmitter, Garmin has developed brand-new proprietary technology that uses sonar.
This allows the signal to travel much further – up to 10m – and connect to up to five transmitters.
With huge potential applications, this new technology could potentially revolutionize the way we dive, and learn to dive, in the future.
Oh, the Garmin Descent Mk2i also functions as a top-tier Garmin fitness tracker and smartwatch – versatile is certainly the word.
The only downside? The cost. At £1,399 not including the transmitter, this model will be too expensive for many divers.

Before Buying A Dive Computer
Still not sure what one to go with, with all these great options? There are a few factors to consider when choosing the perfect computer for you, so let’s go through those, and then I will just give my recommendations and all-time favorites, that you can’t go wrong with.
Obviously, you should think about your budget, check the prices in the links above, and that will be a big factor. But obviously, since there are a lot of options around the same prices, there will be more factors to think about.
Easy To Use And Set Up
This also goes with how much you dive and how much experience you have with computers, but if you are like us, and DO have a lot of dives and experience with computers, yet still prefer something simple and user-friendly.
We have tried a lot of computers, and always seem to revert back to a Suunto. We’d rather not have to spend time figuring out a complicated computer, so we tend to stay away from most Oceanic or Shearwater, unless for tec.
But that’s just our opinion, and a ton of divers love Oceanic computers, with more options and settings.
Why Get Your Own Dive Computer?
Not only does a dive computer make your life much easier, but it also makes your dives much safer. And having your own dive computer means that you are able to accurately keep track of your own limits in real-time throughout the dive.
A dive computer provides you with all the information you need to stay safe and dive within your limits in real-time. It does all of the calculations for you, whilst also providing you with alarms and reminders, for example, automatically tracking your safety stop, applying emergency decompression stops if you exceed your limits, or beeping at you if your ascent is too fast.
None of this can be guaranteed with manual planning and tracking when you use decompression tables and a timing device and depth gauge. Even if you are the most experienced diver with all the knowledge, there is still plenty of scope for human error from the tiniest error in the calculations to not watching your depth for a few minutes of the dive, which can make a lot of difference and put you at risk of decompression sickness.
Besides the safety factor, a dive computer often allows you to make the most of your time underwater as it helps you to monitor your depth and remaining no-stop time during the dive. For example, if you start to shallow up you gain additional no stop time and can spend longer underwater.
Having your own dive computer allows you to be in control of your own safety, maximise your time underwater and helps keep track of your dives so you can update your log book (either manually or many newer models of Bluetooth or USB connections to upload your data to your smartphone or computer).
Can’t I Just Rent A Dive Computer From The Dive Center?
While many dive center’s do offer you the opportunity to rent a dive computer, it can be time-consuming and frustrating to figure out how the different models work. Having your own dive computer means that you know exactly how it works, and how to use it properly to monitor your dives and stay safely within your limits.
Plus, renting dive computers is usually charged per dive and that very quickly adds up across a few days or diving. While a dive computer feels like a big expense upfront it can actually save you a lot of money in the long run. Most dive computers will last you several years, if not decades when taken care of properly (you’ll probably have to replace a battery or two but this is very cheap).
And lastly, having your own computer means that you are using the same computer for all of your dives and it will keep an accurate reading of your no-decompression limits across multiple dives and multiple days of diving.
Frequently Asked Questions
A dive computer is a device, usually worn on the wrist, that provides the diver with all the important variables and information during a dive.
A dive computer records the time and depth of your dive in real time and applies it to a decompression model to track the amount of nitrogren that has dissolved in your body.
The dive computer uses this information to tell you your remaining bottom time or no-decompression limit – how much time you can safely remain at that depth.
A dive computer will also tell you other important information about your dive in real time including your ascent rate, total dive time and help track your safety stop.
Other information a dive computer will tell you includes the temperature of the water, the date and time, and if it is air-integrated it can also track the amount of air left in the tank.
Most modern dive computers are wrist mounted, appearing like a smart watch but you can also get dive computer consoles that can be mounted with your SPG (submersible pressure gauage). Although most divers prefer to have them on their wrists where it’s quicker and more conveneient to monitor their dive info.
A dive computer tells you all the important information about your dive in real time so you can stay within your limits and follow safe diving protocols. All dive computers will tell you the basics including: – Current time and total dive time – Current depth and your maximum depth during the dive – No-decompression limit (no stop time / remaining bottom time) – Ascent Rate – Emergency decompression stops that are required – No fly time – Surface intervals The majority of modern dive computers will also tell you additional information such as: – Monitoring your safety stop – Temperature of the water – Date – Logs of your previous dives Other information that your dive computer may tell you depending on the model and feature includes: – Remaining air (if the computer is air-integrated) – Partial pressures of Oxygen in your body – Compass All of this information helps you to not only track your dives but also to plan your dives.
A dive computer is not mandatory. As long as you have planned your dives using the decompression tables and then accurately monitor your depth and time during the dive using a timing device and your depth guage then you do not need a dive computer. However, the majority of divers argue that a dive computer is the most important peice of dive gear as it allows you to accurately monitor your dive in real time and helps reduce human error. A dive computer will help you to stay within your limits, complete your safety stop and maintain a sae asecent rate – all of which help keep you safe.
Dive computers create a much safer environment for divers and can allow for extended dive times due to the fact they are constantly monitoring and providing new data.
This data can be accessed at all times and give you accurate and safe information on adjusted bottom times, depths, safety stops etc.
They can also normally be set more conservatively if the conditions are challenging or if you have need due to a pre existing medical condition
Dive tables are way less effective as the dive plan has to be worked out pre dive meaning that you would have to stick to a strict plan on the dive.
Where as a dive computer can quickly adjust your bottom time assimilating the data of you actual dive profile.
To be honest using a computer is the only truly safe way of doing multi-level diving as a computer is alway adjusting the time you can reman underwater using the information gathered during that particular dive. Your computer will always warn you when you are staying at a depth too long. These types of dives can be calculated manually but can be difficult to follow underwater due to their complexity. In the end you are diving to immerse yourself in the underwater world, let the computer do all the hard work for you!
