Sealife Digital Pro Flash Universal

The Sealife SL961 is a powerful underwater strobe light. Since the strobe will fire with four different pre-flash settings, as well as no pre-flash, it will work with any underwater digital or film camera that has a built-in flash. Since water absorbs the red and yellow light spectrum resulting in blue pictures you need a flash to bring out the intense colors of the underwater world. It also reduces the backscatter problem that normally will occur when using a camera with a built-in flash.
