Set includes: Fixing bolt, diffuser

A Fiber-Optic Cable will also be required when using the YS-03.
Use of genuine SEAandSEA Fiber-Optic Cables is recommended. SEAandSEA strobes may not function properly if third-party Cables are used (functions such as TTL auto exposure in particular).
 
CAUTION
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 to use, providing the best results at a very affordable strobe.

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. The YS-03 SOLIS is compatible with any camera with a pre-flash and that has a TTL flash exposure function, regardless of make.

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.

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.
