If you’re a scuba diver, investing in a high-quality dive computer is a must. It is an essential part of your scuba diving kit that helps keep you safe underwater. Your dive computer provides you with vital information about your dive like your dive time, depth, ascent rate, gas levels, and more.
Your dive computer can tell you if you’re diving within your limits and warn you if you are not. It is your lifeline underwater, which is why you want it to work as it should. The data it gathers is tailored to your diving and can prevent you from diving accidents like decompression sickness. Taking care of your dive computer can guarantee that it is giving you accurate readings and keeping you away from danger.
Because of its function and purpose, it also comes with a price. If you’re going to invest in a quality dive computer, you want it to last for many dive adventures. By giving your dive computer some TLC aka Tender Loving Care, you can extend the lifespan of your dive computer.
If taking care of your scuba gear is important to you, continue reading for the best tips on how to care for your dive computer. I have been using my dive computer for 5 years now and have followed these best practices for cleaning and maintaining my dive computer.
1. Read the user manual
Take the time to read your dive computer’s user manual before using your device. It may not be the most thrilling read, but it is full of vital information about your first dive computer.
Dive computers are not created equally, and the user manual holds the key to unlocking its full potential. From features and settings to even maintenance, it should be your priority to follow what the manufacturer recommends.
2. Check the batteries
The battery is the life force of your dive computer. No juice means no action, so it’s important to check the status of your batteries before each dive.
Some dive computers need to be recharged while others need to be replaced after so many dives. Always bring your chargers or have your batteries replaced once it shows a low battery warning sign to avoid your dive computers from failing mid-dive. If you can change your dive computer’s batteries yourself, you can also carry a spare with you.
Replace your batteries following the manufacturer’s instructions. Some warranties can be voided if you attempt to replace the batteries on your own.
In most cases, dive computer batteries can last up to 2 years but this also varies on how often you use it. It would be wise to keep a record of when you replace the batteries so you have an idea if it needs replacing soon.
3. Put a protective screen
Scuba diving can be a very rugged activity and you can easily scratch the dive computer display as you maneuver yourself throughout the dive. Scratches are not only ugly to look at but they might make it difficult to read your dive computer. You can avoid damaging your dive computer’s display by putting on a protective screen cover.
Some dive computers come with these protective sheets that you can easily install yourself. But if that is not the case, you can also buy dive computer screen guards in places like Amazon or Scuba.com. Just make sure it’s compatible with your dive computer model.
4. Check screws, buckles, and straps
Part of your dive computer care routine should be to check the hose, buckles, and straps for any signs of damage. As soon as you see any wear and tear, replace it immediately.
I have heard stories of divers losing their dive computers due to straps breaking, never to be found again.
5. Rinse with fresh water after each dive
Another important step in taking care of your dive computer is to rinse it with fresh water after every dive. This removes any salt, sand or other residue that may have hitchhiked with you from your dive.
Pay close attention to buttons and areas where salt or sand may get trapped. You can push the buttons while under the fresh water to loosen anything that may get trapped between the tiny crevices.
Don’t leave it submerged under fresh water for too long as it may keep the device active and consume more battery.
6. Do not expose to direct sunlight
Your dive computer is a computer with very sensitive components. Just like most of your electronic devices, prolonged exposure to extreme heat can cause damage and affect its performance. Avoid exposing or drying your dive computer under direct sunlight. Keep it in a cool and dry place before and after every dive.
7. Use a soft cloth to dry
After rinsing your dive computer in fresh water, you can dry your device using a soft, lint-free cloth. Gently wipe any excess water from the surface and crevices of your dive computer. Don’t worry if you can’t reach some tight areas. Simply dry the computer in a cool and dry spot.
Some dive shops may have compressed air blowers that photographers use to quickly dry their camera housing. Never use this on your dive computer as it may damage its sensors.
8. Backup your dive logs
Your dive computer can also serve as your dive log. It faithfully records your dive history but only to some extent. Some dive computers can only record a handful of dives while some can record hundreds. Whichever dive memory capacity you have, another best practice you should follow is to back up your dive logs.
Many dive computer manufacturers have their own apps or software to help you back up your dive logs to make it easier for you. If keeping a record of your dive is important for you, make it a habit to sync your dive computer with the app after every dive trip.
9. STORE PROPERLY BETWEEN DIVES
When you are not diving, store your dive computer in a dedicated case or protective pouch. If you’re not diving for a long time, occasionally check the unit just to make sure that the batteries are not dead. You want to avoid battery corrosion which can damage the entire dive computer.
When you’re traveling, it is best to hand-carry your dive computer with you instead of putting it in your check-in luggage. This is to avoid theft and also to prevent damage from the rigorous manhandling of your luggage.
10. DO SERVICE CHECKUPS
Another way to care for your dive computer is to send it to regular service checkups with authorized centers. This can help guarantee that the sensors are working well and are calibrated properly. They can also check if all parts are still okay and not damaged from salt corrosion or build up. While these may cost extra, it’s a small price to pay for the peace of mind and safety it brings to your dive.
You can also make it a habit to check for a firmware update. Most times, you can easily update your dive computer firmware using the apps or software the manufacturer provides. If you are not the most tech-savvy person, reach out to the customer service support or service center of your dive computer brand to help you sort this out.
