Tips for Maintaining and Preserving Dive Computers and Dive Watches

Whether it's dive computers or dive watches, digital devices built for scuba diving are amazingly rugged and built to withstand significant depths and other extremes. However, taking the time to properly care for these high-tech instruments will help ensure long life and reliable service.

• Thoroughly rinse with fresh water after each dive and dry with a soft towel to clean away salt and organic material.
• Pay special attention to metal contacts, cleaning occasionally with a soft toothbrush and mild detergent to remove buildup from salt, perspiration, sunscreen and other deposits.
• Most manufacturers recommend service checkups every one to two years for calibration, seal check and function check. This is a great way to avoid problems before they end your dive trip.
• Inspect wristbands and buckles for wear, tears and corrosion. Replace as needed.
• Protect from heat, direct sunlight and harsh chemicals or solvents, which can weaken waterproof seals.
• Store in a cool, dry and ventilated area. Avoid prolonged storage in damp environments.
• When traveling, pack your dive computer with plenty of padding (wetsuits work great), and keep it in your carry-on luggage when possible.

• Double-check and tighten screw-down crowns before diving to prevent leaks.
• Thoroughly rinse in fresh water after diving, paying special attention to clasps and the rotating bezel.
• Submit for service every one to two years for seal replacement.
• Clean metal or rubber bands with a mild detergent and soft brush to remove salt, skin and dirt deposits. Dry thoroughly.
• Have the battery replaced by a dealer authorized to handle watertight cases.
