Sea & Sea YS-02 Underwater Strobe (Head Unit Only)

A manual strobe with exceptional cost performance.
The Sea & Sea YS-02 strobe has a circular beam angle of 100°x100° and guide number of up to 20. The YS-02 is a new compact-type slave strobe that can be used for all applications from wide-angle to macro photography.
 

You can use the YS-02 as a manual slave strobe with the guide number control function, which can set the light level to any of ten levels. Accurate pictures that follow the photographer's intentions can be taken while the light level is adjusted with the guide number controller. The YS-02 is equipped with a pre-flash cancel mode (*1) that is compatible with a wide range of digital cameras with a pre-flash. Power comes from four AA batteries for a powerful and long-lasting strobe, so 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.
You can fully exercise your creativity with the YS-02, 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.

*1 Some digital cameras adjust flash levels after a first flash and then capture an image with a second (main) flash. This first flash is called the pre-flash. The strobe’s pre-flash cancel function ignores the pre-flash and synchronizes the strobe with the main flash.
