SEA & SEA VACUUM & LEAK ALARM UNIT

The SEA & SEA VACUUM & LEAK ALARM UNIT prevents water leakage into your underwater camera housing by creating negative pressure inside the housing and monitoring the change of pressure. The air pressure sensor checks the integrity of your housing's seal before you dive. The leak sensor reacts and issues alerts with an LED indicator if water leaks into the housing during the dive.

Pre-Dive Vacuum Check

It monitors the air pressure inside the housing produced by the vacuum pump, and it displays the status three-color LED lighting/flashing and an alarm.

Ongoing Monitoring

Measures air pressure and occurrence or nonoccurrence of water leakage in the housing every 0.2 seconds (200ms). It constantly monitors the inside of the housing.

Temperature Compensation

Judges the air pressure value by converting the temperature to 68°F. It does not allow malfunction caused by pressure fluctuations due to heat generated by the camera or changes in water temperature.

CR2032 Battery

Battery life is about 250 hours when the power is on. One battery charge enables long-term usage.
