Explore the depths with the Sea & Sea YS-D3 Duo Underwater Strobe, designed to illuminate your underwater adventures in rich, natural color up to 328 feet deep. Compatible with Olympus OM RC, as well as offering traditional TTL and manual operation modes, this strobe is a versatile choice for divers and underwater photographers.

The YS-D3 Duo features a wide beam angle of 105°, expandable to an even broader 110° with the included diffuser. Its daylight-balanced color temperature of 5800K, or 5500K when using the diffuser, brings back the true colors of the underwater world, creating vibrant and accurate images. The strobe's aspherical toroidal lenses ensure even light dispersion without any hot spots, enhancing your underwater lighting experience.

Equipped with a dual-intensity 150/300-lumen LED target light, the YS-D3 Duo aids in focusing and framing your shots. Its backlit control panel displays different colors for each mode: blue for DS-TTL II, orange for OM RC, and green for manual, making it easy to identify your current setting. The strobe also features a 5-pin sync cord connector and a fiber-optic port, ensuring seamless connectivity with your underwater camera housing.
