Sea & Sea YS-03, head only

Fully automatic strobe triggered by light from the camera through a fibre-optic cable.



As the YS-03 has been designed to mimic the light intensity of the camera's built-in flash, it is not necessary to manually adjust power output. The YS-03 is compatible with any camera with pre-flash that has a TTL flash exposure function, regardless of make.

Simple Controls

The YS-03 has been designed for any underwater photographer to use and is easy to understand. The only control is the rotary power switch and by simply turning the switch from OFF to TTL you can take beautiful images.
