The SURVEYOR Moisture Alarm, Vacuum Valve & Pump for Canon EOS 1DX Mark III from Aquatica offers an added level of protection to the underwater photographer. The SURVEYOR circuitry integrates a water detection function that remains on constant duty when a battery is inserted. Should the slightest amount of water make contact with the sensor probes, it will trigger an alarm using both an audible signal and a rapidly flashing red LED to visually attract your attention. Adding the vacuum pump and pressure valve to your housing will make it possible, by creating a vacuum inside the housing, to fully test its sealing integrity. Once the easy-to-follow procedure is completed, a green LED blinking every five seconds will inform you that your SURVEYOR system is monitoring your camera housing and you`re ready to dive. In the event that sand, hair, or other foreign matter would compromise the housing sealing integrity, the SURVEYOR warns you with both an audible signal and a rapidly flashing red LED signal.
