In the diving world, whether you are just starting your journey or just looking to improve your dives, dive computers in 2024 are essential. A dive computer stores important information and keeps your dive safe. There’s a scuba dive computer for every diver, so when you are in the market for one, consider your diving needs and habits.
Are you a tip-top shape diver? A conservative diver? A long-hours-and-multiple-dives-in-one-day diver? All of these variables will determine what kind of gear you will need.
What is a dive computer?
A dive computer is a sophisticated electronic device used by divers to enhance safety and optimize dive planning. It tracks essential data such as depth, time underwater, and nitrogen levels in real-time, helping divers avoid decompression sickness by calculating safe ascent profiles. Additionally, it offers features like no-decompression limit tracking, dive log storage, and alarms for critical events. By providing instant and accurate information, a scuba diving computer enables divers to make informed decisions during their underwater adventures, making diving safer and more enjoyable.
A basic and primary feature of all dive computers is the fact that they measure depth. Its measurement of depth is a lot more accurate than an average analog depth gauge. Based on your dive’s duration and depths, a dive computer calculates how many decompression stops you need to make and at what depths. It also calculates the surface interval time you need to spend between dives and also calculates when it is safe to fly after diving. These are all important for divers who rely on air travel at the end if their diving vacations.
Dive Computer Styles
There are essentially two types or styles of dive computers available: wrist or watch style, and console or module dive computers.
Wrist-Mounted Dive Computers
The more popular choice among recreational divers today, mainly for their convenience, wrist dive computers as the name implies are worn on the wrist by the diver and look like large-faced watches. An advantage this style of dive computer has over the console-mounted style is that as it’s not connected to your other gear. It’s more versatile to be used with any scuba kit. Some examples are:
Console Dive Computers
The console dive computer is a slightly more economical option. It is attached to other scuba gear via a hose and typically come with a pressure gauge, unlike the most wrist mounted options (excluding air-integrated wrist computers). The advantage of this style is that the it is sometimes easier to read as the display is fairly large.

What to Look for in a Dive Computer
Selecting the right scuba dive computer is essential for a safe and enjoyable underwater experience. Several key factors should be considered to ensure you make an informed choice:
Interface
The first thing you’ll need to ensure is that the computer has a user-friendly interface, especially if you’re a beginner. It doesn’t have to be incredibly plain, as long as the elements on the display are arranged in a way that you can easily understand at first glance. Of course, you also have to make sure that it is easy to read even in darker environments, which is usually the case underwater, so choose one that has good backlighting.
Dive Modes and Gas Compatibility
Choose a dive computer that supports the dive modes you intend to use, whether it’s recreational, nitrox, trimix, or rebreather diving. Ensure it’s compatible with the gases you plan to use during your dives.
Algorithm
The dive computer’s algorithm is crucial for calculating decompression limits, ascent rates, and other critical data. Look for a well-established algorithm that has been tested and proven to enhance diver safety.
Ease of Use
User-friendly interfaces and intuitive menus are vital, especially for beginners. Navigating through settings and accessing dive information should be straightforward.
Audible and Visual Alarms
Alarms for depth, ascent rate, decompression limits, and other important alerts are crucial for safety. Ensure the dive computer offers both audible and visual alarms.
Battery Life
It helps to get a dive computer that has the capability to warn the diver about low-battery life, so they can replace it before starting a dive. This will ensure that your dive computer has more than enough power to continuously calculate changes in the dissolving nitrogen in your body.
Also, make sure to check if the battery on your dive computer can be easily changed without the assistance of a technician. Older models may need to be serviced before dives to ensure that the battery will be able to function well throughout the next dive.
Size and Comfort
The size and fit of the dive computer should be comfortable on your wrist. Bulkier models might not be ideal for everyday wear.
Wireless Air Integration
This feature allows you to monitor tank pressure directly on your dive computer. It’s a convenient way to keep track of your air supply.
Durability
Look for a dive computer built to withstand the underwater environment. Rugged construction ensures it can handle the pressures and potential knocks of diving.
Logbook and Connectivity
A comprehensive logbook feature stores your dive history, aiding in post-dive analysis. Some dive computers can be connected to your laptop or PC to allow you to export your dive data. Serious divers often consider this an important feature as it helps them obtain detailed dive information and keep them organized in a digital dive log.
Price
Set a budget and find a dive computer that meets your needs within that range. Remember, safety is paramount, so consider it an investment in your well-being.
Future Growth
Consider your diving goals. If you’re planning to advance your diving skills, look for a dive computer that can accommodate your future needs.
