Why This Kit Matters:
A reliable dive computer is essential underwater, and it depends on two things: a strong battery and a watertight seal. An old O-ring or weak battery can lead to power failure, moisture intrusion, and costly repairs. This replacement kit refreshes both at once, keeping your computer secure, powered, and dive-ready.
Key Benefits:
- Peace of Mind: Fresh battery and new seal ensure your device is ready for every dive.
- Protects Your Investment: Prevents leaks, corrosion, and premature equipment failure.
- Easy Maintenance: Everything included for a proper battery change in minutes.
- Travel Friendly: Compact, lightweight kit is perfect for dive trips and spares.
Installation Tips:
- Clean the battery compartment with a lint-free cloth before installing new components.
- Apply a thin layer of the included O-ring lubricant to the new seal to reduce wear and improve protection.
- Seat the O-ring carefully without twisting or pinching to maintain a proper seal.
- Insert the new battery, close the hatch securely, and test your dive computer before your next dive.
