Sealife Sea Dragon Universal Flash Head

By SeaLife


The Sea Dragon universal underwater flash/strobe head works with all cameras with a built-in Flash. This head-only version, is just like the complete SL963 Sea Dragon Universal Flash, excluding the grip, tray and EVA travel case. The Flash offers both automatic and variable power adjustments with an effective UW distance range up to 8feet/2.5m. The “Auto Learn Mode” easily syncs your cameras pre-flash for easy set-up and use with your camera. For best results, we recommend rechargeable Panasonic Eneloop Pro 2550mAh Ni-MH batteries (4 –not included). The Sea Dragon Flash head includes a snap-on diffuser that spreads light out evenly, especially for close-in shooting. For distance, use the flash without the diffuser.
