Ikelite SubStrobe SS-100a Photocase Underwater flash

The SubStrobe 100A is the value leader in a strobe capable of covering wide-angle lenses underwater.

The electronics are completely sealed from the battery compartment. The strobe provides approximately 160 flashes from four "D" cell alkaline batteries. Full power recycle time is less than four seconds. This product comes with waterproof photocase.
