Types of Scuba Diving Computers

Understanding the types of scuba diving computers is an important step for every keen diver. Recreational diving computers are designed to offer basic data such as dive time and decompression stops and are best suited for everyday recreational use. On the other hand, technical diving computer models are the choice for more experienced divers who engage in complex ocean escapades, as they have multiple gas support and provide a range of preset customizations. Lastly, rebreather diving computers are essential when exploring beneath the surface with a closed-circuit rebreather system - they provide deep logs, access to multilevel dives, and improved safety thanks to their constant monitoring of parameters such as dive time and oxygen levels. Ultimately, understanding each type of scuba diving computer is paramount for mastering the underwater domain.

Tips on How to Maintain Your Scuba Diving Computer

Maintaining your scuba diving computer doesn’t have to be a laborious process. Taking proper care of your device will help ensure you are kept safe and well informed during your dive. Routine cleaning and careful storage can go a long way in keeping your diving computer functioning properly for years to come. Make sure that you understand the difference between recreational, technical, and rebreather diving computers so that you choose the one best suited for your needs - this will also determine if additional maintenance is needed for its optimal performance. Once you have identified the make and model of your device, it’s important to register with the manufacturer as this allows access to any potential technical support resources provided. Consult the manual to familiarize yourself with all features associated with that model, reach out to knowledgeable dive experts, or join online communities devoted to discussing feedback and tricks on how they maintain their own computers. Although a regular maintenance routine may seem tedious at first, following these steps will ultimately keep you safe while scuba diving and avoid any unnecessary dives due to incorrect settings.

What is the Best Dive Computer to Buy for Scuba Diving?

Dive computers are one of the most essential pieces of scuba diving equipment that you can buy. Considering that they help to keep you alive, they are a small price to pay. Most dive computers start with the same basic functions:

  • No Decompression Times: They tell you how long you can stay at that depth without increasing your chances of suffering from decompression sickness (excessive nitrogen bubbles that appear in your body after a dive).
  • Accurate Depth Measurement: They tell you how deep you are so you don’t exceed your certified maximum depth or dive to unsafe depths. Insurance companies will try to get out of any pay-outs if you exceed your maximum depths for your qualification and a dive computer is your proof that you haven’t.
  • Surface Interval and Residual Nitrogen Time: They work out your surface interval and your residual nitrogen time when you do repeat dives.
  • More Accurate Than Tables: They give you more bottom time as they readjust the no decompression time as you ascend.
  • Safety Stop Countdown: Most dive computers now include a countdown for your safety stop.
  • Decompression Steps: If you do go into decompression, they tell you what steps you should take such as ascending to a particular depth and staying there for a set amount of time (air permitting).
  • Ascent Rate Monitoring: If you ascend too quickly, they will tell you to slow down.
  • Nitrox Compatible: If you are qualified to use Nitrox, you can set the dive computer to the Oxygen levels and this will increase your underwater time accordingly and warn you if you exceed your maximum operating depth for that %O2.
  • Data Upload: You can link a cable to your PC and upload the information to an online dive log.

Once you get past the basic computer then there are other features you might wish to consider that some of the more expensive models include such as:

  • Air Transmitter: This allows you to more accurately monitor your current air pressure and it will tell you how long your air will last at your current depth at your average breathing rate.
  • Multiple Gases: As you become a more experienced diver you may look to move to more technical diving that will allow you to have more than one cylinder with different levels of Oxygen.
  • Bluetooth Connectivity: You can link your dive computer to your phone, tablet, mac, or PC and download all of your dive data to an online log book kept on the internet. A great gadget for tech geeks as well as divers who like to keep an accurate record of their dives. You can normally upload your photos and maps against each dive and you can also leave notes. Not only is this useful if you come back to the dive site again but you can share it with other divers and your social media.
  • User-Changeable Batteries: Traditional dive computers required you to send off your computer for a battery change. This can cost up to £50 as they require pressure testing to ensure there are no leaks. Some computers now allow you to change the battery yourself at a fraction of the cost.
  • Rechargeable Batteries: Simply plug your dive computer into a USB port and it will recharge the computer for you. Once charged they normally last for around 20 dives. Some computers can even charge via a solar panel on their face.
  • LCD Displays: These tend to be easier to read than traditional grey matrix computers, especially on a night dive.
  • Electronic Compass: This means strapping fewer toys on your arm and/or gauge and you can also mark directions so you can track your way back.
  • Technical Dive Computers: These will future-proof yourself if you wish to move on to mixed gases, tri-mix, and rebreathers.
  • Upload Dive Maps and Photos: On your computer to aid navigation and your fish ID skills.

Once you have decided what functions appeal to you then there are 3 main styles of computer:

  • Wrist Style: This is the standard style dive computer that is generally easy to read and sits on your wrist.
  • Watch Style: These are great for diving on holiday as they can be used like a watch when not in the water and have all/most of the same functions of their larger brothers (but tend to be more expensive).
  • Console Computer: This replaces your current pressure and depth gauge that is attached via a hose to your regulators. They are very popular in America but less so in Europe – for no real reason really.

Other considerations aside from budget are what material do you want the computer and strap to be made from such as lightweight titanium.

As with most things, it comes down to personal preference but here is a list of our recommendations and their reasons why:

Entry Level

  • Wrist Style Computers
    • Suunto Zoop: Used the world over and has all the basic functions you’ll need.
    • Suunto Vyper: Perfect for divers who want a little more than basic. Clear screen, intuitive menus, and the option to add air integration later as your diving progresses.
  • Watch Style
    • Aqualung i770R: Compact watch design but with advanced features like air integration and compass.  
    • Garmin Descent Mk3i (Entry-friendly for future upgrades): Full colour AMOLED display and smartwatch features make it a future-proof choice if budget allows.

Intermediate Level

  • Wrist Style
    • Suunto EON Core: Large colour screen, air integration and rechargeable battery make it perfect for divers stepping up from entry level.
  • Watch Style
    • Suunto Ocean: Combines sport watch adventure features with solid dive functions — ideal for active divers who dive regularly.
    • Garmin Descent Mk3i: High‑resolution AMOLED, air integration tech, GPS and smartwatch features — great for divers who want more than basics.

    • Garmin Descent Mk3i: Top-end AMOLED display with full air integration, GPS, multiple gas support, and advanced modes — great for advanced recreational and technical divers who want sports watch functionality.

 

Do I Need A Dive Computer?

The best analogy I can think of is to imagine you do not have a fuel gauge in your car. You would need to guess how much fuel is left in the tank and get to a petrol station before you run out. Imagine you guess wrong, you’re driving down the motorway at 70mph and you suddenly grind to a halt in the outside lane. Far from ideal I would suggest!

A dive computer is similar, it tells you how long you can spend at a given depth and updates itself as you ascend and descend (your no decompression time). On top of this, they will tell you if you ascend too fast, how deep you are, how long your safety stop needs to be, and if you have a top-of-the-range computer will tell you exactly how much air you have left, how long it will last for, and alarms will trigger if you push the limits too far.

Many countries such as the Maldives insist that you wear a dive computer by law. Most respectable dive centres will also insist you have one, especially if you are diving beyond 18m.

Failure to wear a dive computer severely increases your risk of DCI. What about the old dive tables you may ask? Good question. Have a think back to the last time you were diving and try and remember how many people were planning their dive with the tables? In 20 years of diving, outside of training, I have never seen anyone do it. Instead, I see people (when I’m on holiday) just following their guide and hoping that they know what they’re doing and leaving it to luck. The other problem is that dive tables don’t really account for multilevel diving or aren’t as accurate. Therefore, a dive computer will give you a much longer dive time if your dive is to various depths.

For a piece of equipment that can potentially save your life, they don’t have to be expensive. You can get a perfectly adequate dive computer for under £200. You can hire computers for around £10 per day but if you are going to use it more than one day a year then it’s probably worth investing in your own – that way you can learn to use it properly too!

There are 2 main types of computer, a larger wrist style computer. These tend to be cheaper and have a larger screen, and a watch-sized computer that can be worn as a watch.

So the answer to the question, do I need a dive computer is YES!!!!

We carry a range of dive computers for all tastes and budgets so order yours today.
