11 Top Tips for Selecting and Using Freediving Computers
November 28, 2024
Looking to buy a freediving computer? It is one of the most important purchases for freediving; it helps you monitor your dives and stay safe, and it helps you track your progress over time. But with so many freediving computers available, selecting the right one can be a challenge. Discover essential tips for choosing the right model, key features to consider, and expert advice on maintenance and care here.
Why Freediving Computers Are Essential
Freediving computers track the vital statistics of your dive and can help improve your freediving abilities by providing detailed feedback. Unlike scuba diving, where time spent underwater is supported by breathing apparatus, freedivers rely on holding their breath, which makes precision in monitoring dive depth and time even more critical. A reliable freediving computer provides real-time data to help prevent issues such as shallow water blackout or hypoxia and ensures you are diving within your limits.
Freediving v Scuba Diving Computers
Though both freediving and scuba diving computers track underwater performance, they serve different purposes and have unique features designed for the specific needs of each sport.
These devices focus on key metrics like dive depth, dive time, surface interval, and descent/ascent speed. They typically have shorter depth alarms and interval timers, as freediving dives are usually shorter but more frequent than scuba dives. Some freediving computers also include apnea-specific training modes, which can help divers practice breath-holding techniques on land.
Scuba computers are designed to monitor breathing gas mixtures, nitrogen absorption, and decompression limits. They typically include air integration for tracking gas consumption, which is irrelevant for freediving. Scuba computers also provide information on no-decompression limits and have alarms related to nitrogen saturation.
That said, there are similarities. Both types of computers are built to withstand harsh underwater environments, are waterproof, and feature depth and time tracking. Some computers offer dual modes, meaning they can be used for both freediving and scuba diving.
However, while some scuba diving computers have freediving modes, they may not offer all the specialized features that a dedicated freediving computer would provide.
Top Tips for Selecting the Right Freediving Computer
Selecting the right freediving computer depends on several factors, including your experience level, dive goals, and budget. Here are some top tips to help you find the best fit for your needs:
1.Understand Your Diving Needs
If you are a beginner freediver, you may only need a basic computer with depth, time, and surface interval tracking. For more advanced freedivers, computers that offer features like ascent/descent rate monitoring, depth alarms, and customizable training modes will be more beneficial.
2.Research Brands and Reviews.
Each brand and model of freediving computer has its unique strengths and might cater to different aspects of diving. Comparing them helps you find the most reliable and user-friendly device.
Your local dive center is a valuable resource for trying out different freediving computers and getting hands-on advice. Feedback from freediving instructors can provide insight into the performance and reliability of various computers.
Also, chat with other freedivers in online diving communities such as Underwater Explorers Worldwide. Listening to their first-hand experiences will help you select the right freediving computer for your needs.
Looking for a recommendation? The Mares Smart Apnea is a highly popular choice for both beginner and advanced freedivers. It offers all the essential functions, including depth, time, and surface interval tracking, along with a customizable depth alarm.
3.Ensure it is User-Friendly
Choose a computer that has a user-friendly interface. Freedivers need to be able to quickly glance at key metrics like depth and time, so clear, easy-to-read screens and intuitive menus are crucial.
4. Consider the Features You Need
Features like surface time monitoring to give you the correct amount of time to recover and depth alerts to maintain safe diving depths are vital features of freediving computers. Some freediving computers offer integration with mobile apps that can analyze your dive data, allowing for a deeper insight into your performance and progress.
5. Make Sure it is Comfortable
A freediving computer should be comfortable to wear for long periods and not obstruct your movement underwater. A good fit ensures the device can be worn over a wetsuit and remains securely in place throughout the dive.
If possible, try on different models before purchasing or ask for recommendations from experienced divers to find the best fit and comfort. You can always try a freediving computer on over some clothing to simulate the wear over a wetsuit.
6.Check the Depth Rating
Freediving computers are typically rated for depths greater than what most freedivers will encounter. However, if you are progressing to deeper dives, be sure to select a computer that has a higher depth rating. Most freediving computers can handle depths of 100 meters or more.
7.Durability is Key
Freediving involves repetitive dives and constant exposure to saltwater, so durability is a key consideration. Look for a robust waterproof design and a scratch-resistant screen. Some models are equipped with stainless steel or titanium components for added longevity.
8.Check the Battery Life.
Freediving computers tend to have longer battery life than scuba computers, but it is still important to choose a model that will last for several diving sessions without needing frequent recharging.
The battery life can vary widely but typically lasts between 200 to 300 dives depending on usage and settings. Some computers offer user-replaceable batteries, which can be a convenient option.
9.Ask About Training Features
Many freediving computers now come with specialized apnea training features, such as carbon dioxide and oxygen tables, which help you improve your breath-holding capabilities. If you are serious about training and improving performance, these added features can be very useful.
10.Is it Compatible with Your Dive Log?
Some freediving computers allow you to download your dive data to a smartphone or computer, making it easy to analyze your performance over time. If you are interested in tracking your progress and improving your technique, make sure the model you choose offers this capability.
Make sure you also download the MySSI app. This impressive free app has everything you need related to scuba, freediving, technical diving, and mermaiding.
11.Know Your Budget
The price for a reliable freediving computer varies from $200 to over $1000, depending on the features and brand.
Computer Maintenance and Care
A well-maintained freediving computer will serve you for years. Here are some essential tips for keeping your device in good condition:
- Rinse After Every Dive: Always rinse your computer in fresh water after diving, especially after saltwater dives. Check the battery level before every dive session. For models with user-replaceable batteries, ensure you have a spare battery on hand.
- Store in a Cool, Dry Place: Keep your computer out of direct sunlight when not in use, as excessive heat can damage the screen and internal components. It is also a good idea to store it in a protective case to avoid accidental damage.
- Perform Regular Maintenance: Follow the manufacturer’s recommendations for maintenance and servicing. Some freediving computers may need seals or buttons checked and replaced periodically to ensure water resistance.
- Update Software: If your freediving computer allows for updates, make sure you update it regularly. Manufacturers often release updates that can improve functionality or fix minor bugs.
