Sea and Sea YS 03 Universal Strobe Lighting System


Sea and Sea YS 03 Universal Strobe Lighting System

YS03 TTL strobe photography with this very easy to use, compact affordable, underwater strobe.

YS-03 (Black) (Product No.03116)

*A Fiber-Optic Cable will also be required when using the YS-03.
* When the YS-03 is used with a non-SEA&SEA housing, a Strobe Mask Set may be required along with the Fiber-Optic Cable.
*Use of genuine SEA&SEA Fiber-Optic Cables is recommended. SEA&SEA strobes may not function properly if third-party Cables are used (functions such as TTL auto exposure in particular).

Do not use non-recommended batteries (such as lithium primary batteries). Use of non-recommended batteries may cause battery leakage and overheating and may cause the strobe to rupture, which could result in personal injury.

Easy and Versatile Slave TTL
Easy and Versatile Slave TTL
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 output. The YS-03 is compatible with any camera with a pre-flash and that has a TTL flash exposure function, regardless of make.
Comes with diffuser as standard
The half-translucent section diffuses and softens the light from the strobe. Using the diffuser gives softer, more evenly exposed images. The diffuser will also help reduce effects of overexposed images or when strong light produces shade/shadow in the image.
Charged and ready to trigger.
TTL exposure confirmed.
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.
