The Sea and Sea YS-D1 Strobe sets a new standard for underwater strobes. From subtle light output as low as guide number 1 to a maximum power of guide number 32, control of underwater lighting has become effortless with the Sea and Sea YS-D1 Strobe.
Equipped with SEA&SEA’s new slave TTL system called “DS-TTL ll”
Revising the algorithms used for the DS-TTL system, the Sea and Sea YS-D1 Strobe employs a totally new slave TTL system. The strobe can adjust the interval between the pre flash and the primary flash in order to be compatible with a wide-variety of cameras, if not all, on the market today. The strobe is equipped with DS-TTL ll mode which is more responsive, more precise and more reliable. The DS-TTL ll enables a variety of strobe sync photography such as slave TTL and slave manual (11 steps) with compact or digital SLR cameras. When used with a digital SLR camera in housing, the strobe can also be connected with a conventional sync cord and through a YS Converter for TTL strobe photography. In a clear water environment, two Sea and Sea YS-D1 Strobe in DS-TTL ll mode provide perfect lighting. When you would like to emphasize contrast, setting the main strobe in DS-TTL II mode and the secondary strobe in manual mode (11 steps) offers flexibility without limiting control. When underwater visibility is poor, two Sea and Sea YS-D1 Strobes set to manual mode may produce the best images.
