SEA LIFE UNIVERSAL FLASH HEAD The powerful and compact Sea Dragon Universal Flash makes it simple to add light and color to your images down to 200 feet/60 meters. Producing rich, deep colors in underwater photos, the Sea Dragon Flash is compatible with SeaLife camera models, and most other brands of underwater cameras that use an internal flash. The Sea Dragon Flash head- only (SL9631) configuration contains everything that the SL963 kit has, except grip, tray and Sea Dragon case. Variable power adjustment and large controls make it easy to fine tune brightness, while leaving the flash in Auto Mode automatically adjusts brightness. Use the Auto Learn Mode to easily sync the pre-flash with your camera by selecting Auto Brightness or by manually adjusting the brightness for optimal exposure. A quick-release button detaches flash head for aiming in hard to reach areas. The included diffuser spreads light out evenly, preventing a hotspot and backscatter.
