Prevent leaks and keep your valuable investment safe with Aquatica's SURVEYOR Moisture and Vacuum Sensor, which is compatible with their AGH4 Underwater Housing for the Panasonic GH4 digital camera. It is sensitive to atmospheric pressure and allows you to confirm watertight integrity before diving. The sensor can be turned on and off. Once your camera is installed, simply push the start actuating button integrated on the sensor's circuit board.
LED light will turn green for two seconds to confirm actuation
With optional valve and extracting pump, which are part of Vacuum Circuitry Kit, you can remove excess air to create a vacuum in housing
Once solid vacuum is achieved, LED will blink green again for two seconds
During dive, LED will flash green every few seconds, indicating system integrity
If vacuum starts to decrease, LED will start to flash orange
If water is detected, audible alarm will go off and LED will also flash red
Advanced Aquatica circuit has temperature compensation included, so any change in ambient or internal temperature will not cause incorrect reading
Onboard start actuating button is for vacuum only; your alarm is always on
Housing can be purchased with this system pre-installed at factory before shipment, in which case this one will serve as spare or replacement
If you purchased housing without this kit initially, you can now add it on
