SEA&SEA Dual Sync Cord Adapter for Two Strobes This is an adapter used when you want to connect two underwater strobes to a SEA&SEA underwater camera. It can be used with models like the Motor Marine II. Simply put, it's like a Y-splitter for strobe sync cords. This is a rare item, and it's unlikely to be listed again. As shown in the first photo, there is a small crack that has been repaired with adhesive, but it does not affect its functionality. Using two strobes allows light to spread evenly, resulting in truly wonderful underwater photos. Why not start your two-strobe underwater photography journey with this?
