EXTERNAL FLASHES

Underwater flashes and strobes were designed to improve the color, lighting and quality of your
underwater images. Since light and color are absorbed by water, using an external flash is recommended in
all depths, during daylight and night dives. In addition to retrieving the color and light absorbed by water,
underwater flashes also allow for creative lighting, assist in reducing the amount of backscatter and prevent
the shadowing effect caused by the housing lens port when using the built-in camera flash, especially when
accessory lenses are mounted on the housing.
The FG7X II S Housing can be used with underwater slave flashes. These external flashes feature a slave
sensor which triggers the external flash to fire in sync with the internal camera flash.
Most underwater slave strobes are capable of synchronizing with the internal camera flash without any
cables under certain diving conditions. They feature a slave sensor that triggers the strobe to fire in sync
with the camera built-in flash as long as the strobe and the camera are positioned on the same axis and as
long as there is not much ambient light available. However, if the strobe slave sensor isn't pointed directly
at the internal camera flash, or when photographing during daylight, in clear water and bright conditions,
the slave sensor might fail recognizing the output of the internal camera flash. Connecting a fiber optic
cable between the internal camera flash and the slave strobe ensures full synchronization in all angles and
diving conditions.
Attaching Fiber Optic Cables to the Housing
1. When installed on the housing, the fiber optic cable plate allows for an easy attachment of up to 2
fiber optic cables to the housing.
2. Remove the Fiber Optic Cable Plate from the housing. Insert your fingers beneath the adaptors
installed inside the plate and push the plate upwards till it is removed from its slot.
3. The Fiber Optic Plate receives most fiber optic cable brands, including Sea&Sea. In most cases, the
plugs installed inside the plate can be removed and the fiber optic cable can be installed using the
plug it comes with. If attaching fiber optic cables which already feature an adaptor:
a. Housing adaptors should first be removed from the fiber optic cable plate. Use a pen or
screwdriver to gently push them out of the plate. The adaptors should be pushed from the
back of the plate and pulled out from its front side. Make sure not to damage the fiber optic
cable plate when doing so.
b. It's recommended to apply some silicone grease on the small o-rings of the adaptors
installed on your fiber optic cables, so they can be installed and removed more easily.
