The Sea & Sea YS-02 Strobe Package features the YS-02 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. Manual exposer control is easy, since the strobes have a ten-level power dial located on the back. The YS-02 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.
It is best to connect the strobe to the housing with the included fiber optic cable. One Sea & Sea fiber-optic L-type cable is included. Use it to connect the built-in sensor on the Sea & Sea strobe to the built-in flash on the camera. When the camera's internal flash fires, the cable will fire the YS-02 strobe. The L shaped connectors resist bending and have improved light conducting efficiency. The included Sea & Sea Strobe Mask Set is used to attach the Sea & Sea fiber-optic cable to many manufacturers' underwater housings. The mask blocks the on-camera flash from exposing your subject. This prevents back-scatter. The grommet allows the cable to be attached in front of the on-camera flash so the light will trigger your external strobe.
Also included Sea & Sea Grip-Stay S is designed to attach the YS-02 to small camera housings. To keep things stream-lined you can pass the fiber optic cable through the grip. 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.
