SEA&SEA YS-01 Solis Strobe
The SEA&SEA YS-01 Solis Strobe, the best-selling strobe in its class, has been redesigned to offer improved performance. Featuring DS-TTL II circuitry, this strobe automatically adjusts the light intensity based on the light output from the camera’s onboard flash. With this function, even an inexperienced underwater photographer can intuitively control the desired light level. The strobe also allows you to adjust the light intensity from the programmed standard exposure, making it easy to fine-tune the lighting for your specific needs.

Important Notes
- A Fibre-Optic Cable is required when using the YS-01 strobe.
- If using the YS-01 with a non-SEA&SEA housing, a Strobe Mask Set may be needed along with the Fibre-Optic Cable.
- For optimal performance, always use genuine SEA&SEA Fibre-Optic Cables. Non-recommended cables may cause issues, especially with TTL auto exposure.
CAUTION: Do not use non-recommended batteries (such as lithium primary batteries). These can cause battery leakage, overheating, and may even cause the strobe to rupture, leading to personal injury.
