Capture higher quality images underwater with the Ecko DS Underwater Strobe from Ikelite, which provides illumination at depths as low as 328'. The Ecko DS is one of the smallest and lightest strobes in its class, weighing less than one pound per strobe. The compact size makes it simple to transition from macro to wide angle capturing. When used in TTL mode together with a compatible TTL converter, your camera will meter the scene and adjust strobe power automatically.
