You can switch between DS-TTL (Digital Slave TTL) and a ten-level manual control function, to enable fine adjustment of the light level according to the photographer's intentions. You can also set up a lighting system that uses two strobes in DS-TTL mode. Power comes from four AA batteries for a powerful and long-lasting strobe. You can enjoy taking pictures all day long without having to recharge the batteries. The recycle time takes about two seconds with nickel-metal hydride batteries (2700 mAh) for stress-free continuous shooting. The YS-01 is furnished with a high-luminance white LED target light (1W) indicating the optical axis of the strobe attached to its front face that is effective for night diving.
You can fully exercise your creativity with the YS-01, which can be used as a primary strobe or secondary strobe in a wide range of applications, from compact digital cameras to digital SLR cameras.

The Sea & Sea YS-01 is a compact slave strobe that can be used for wide-angle or macro photography. With its circular beam angle of 100 x 100° and a guide number of up to 20 it is the perfect strobe for small Point & Shoot cameras or DSLRs. The DS-TTL (Digital Slave TTL) feature gives you automatic exposure control when shooting in slave mode. It is best to connect the strobe to the housing with a fiber optic cable. For finer lighting control it is best to shoot in manual mode. This is easy since the YS-01 has a ten-level power dial located on the back of the strobe.

The YS-01 is powered by 4-AA batteries. You can get up to 330 flashes at full power with NiMH batteries. With NiMH batteries you will get a blazing fast 1.9 second recycle time, so you will not miss all the action on the reef. The YS-01 has a bright 1W LED target light, that is bright enough to use as a dive light on night dives.

An external flash is your most important accessory. The ocean is one big, blue filter. As you descend, the reds and oranges quickly become muted shades of blue and gray. Using a color corrected strobe light will bring back your subject's natural color.
