The Ikelite AQ/s flash is designed to be used with the Ikelite Aquashot 3 and 3e housings. Using this external flash underwater will increase the natural color of your photographs as well as eliminate the effect of snow ( backscatter) that often occurs when using a camera's built in flash.
The kit also includes a travel bag as well as the macro kit that allows you to photograph objects as close as 8".
