Maintaining your dive computer's depth sensor is critical for ensuring its longevity and reliable performance. Here’s a comprehensive guide to prevent unnecessary damage and extend depth sensor lifespan.
Gentle Cleaning and Rinsing
Depth sensors are highly sensitive to pressure and impact, so it’s important to avoid using high-pressure water, such as hoses or jet washers, as well as compressed air or physical tools to scrape away debris. Instead, you should gently rinse the sensor with fresh water after every dive to remove salt and dirt. Soaking the computer in lukewarm water for 20–30 minutes is particularly effective, especially if you periodically operate any mechanical buttons during the soak to keep them functioning smoothly. Never poke or directly touch the sensor, as this could cause damage.
Avoid Thermal Stress
Depth sensors are also vulnerable to extreme temperatures, particularly if water trapped inside the device freezes or if the unit is exposed to excessive heat. To prevent thermal stress, store your dive computer indoors at a stable, comfortable temperature after thoroughly rinsing and drying it. Avoid leaving it in hot cars or freezing environments for long periods, and ensure the device is completely dry before exposing it to cold conditions to prevent ice formation.
Avoid Ionized Air
Ionized air from appliances like air purifiers, hair dryers, or ozone generators can damage the sensitive components of your depth sensor over time. To protect against this, avoid storing your dive computer near these types of devices. Storing the computer in a clean, stable environment will help preserve its performance.
Minimize Chemical Exposure
Prolonged contact with harsh chemicals, such as those in heavily chlorinated pools, can degrade the protective interface of your depth sensor. After using your computer in chemically treated water, rinse and soak it thoroughly to remove any residual chemicals. Allow the device to rest for one to two days between extended exposures to chlorine to help maintain its integrity.
Proactive Maintenance
Even with excellent care, wear and tear is inevitable. Regular inspections and maintenance can help you catch potential problems early. For optimal performance and reliability, it is recommended to service your Shearwater dive computer every two years.
By following these simple yet effective guidelines, you can maximize the lifespan of your depth sensor. Protect your gear, and it will protect you.
