Product Information

Sharp, bright underwater images

The Sea Dragon Duo Flash Set includes two Sea Dragon Universal Flash strobe heads, Flex-Connect Dual Tray and two Flex-Connect Grips. The set provides powerful, yet controllable light to bring out amazing colors in your underwater photos. The included diffusers reduce backscatter and eliminate shadows with nearly two times the light coverage over the single Sea Dragon strobe. The Duo Flash set is universally compatible with all underwater cameras with an internal flash and standard tripod mount. Because of the added second strobe, it is highly recommended to add several optional Flex-Connect flex arms to the set to spread the light out for even and thorough illumination of the subject.

Adjust your settings for any dive environment

Variable power adjustment and large controls make it easy to fine tune brightness, while leaving the flash in Auto Mode automatically adjusts brightness for optimal exposure. Quick-release buttons detach flash heads for aiming in hard to reach areas.

Easily expand with Flex-Connect accessories

Quickly and easily expand Sea Dragon lighting with Flex-Connect Flex Arms and other accessories. Flex-Connect allows you to transform your camera set from compact to full-featured in just seconds, providing a quick way to adjust to any dive environment. Assembly and set up is always quick and easy so you can spend more time snapping great underwater pictures!
