The New YS-03 Lighting Package is now available from our Stockists.

The YS-03 Strobe is a simple to use, DS-TTL only strobe that has been desined for any underwater photographer to use.

The only control is a rotary power switch and by simply turning it on, you can take beautiful underwater images.

The strobe is compatible with any camera with a pre-flash that also has a TTL Flash Exposure function, regardles of make.

The Lighting Package includes the Strobe Head, a Fibre-Optic Cable II plus a Flexi-Arm and Tray, all you need to add lighting to your underwater housing.

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 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.


Charged and ready to trigger.

TTL exposure confirmed.

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.

*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).
