Sea & Sea YS-03 Solis TTL Underwater Strobe

New and Improved! The YS-03 Solis is now more reliable than ever! Built with the latest technology, this TTL only strobe offers no compromise on performance, allowing users to take first class pictures in a simple fashion.

Simple Controls

The YS-03 Solis 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.

Easy and Versatile Slave TTL

As the YS-03 Solis has been designed to mimic the light intensity of the camera's built-in flash, it is not necessary to manually adjust output. This strobe 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.
