The Aquatica SURVEYOR Moisture Alarm for Canon EOS 7Dfrom Aquatica SURVEYOR Moisture Alarm for Canon EOS 7Doffers 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.

This kit includes the moisture and vacuum sensor circuit, a pressure valve with retaining nut, a vacuum pump, mounting hardware, a container of O-ring lubricant, and a CR2032 battery.

Q: 1. CF card requirements?

A: I use Lexar Professional 32 GB 1066x . All of the Sandisk and Lexar cards from 16 to 64 are good cards. It depends on what you are shooting.
