Capture high-quality images underwater with the Ecko Fiber Underwater Strobe from Ikelite, which provides illumination at depths as low as 328'. This strobe utilizes a fiber optic cord, which is thinner and lighter than an electrical sync cord and can be removed while wet or underwater. The Ecko Fiber is one of the smallest and lightest strobes in its class, weighing less than one pound per strobe. Its compact size makes it simple to transition from macro to wide-angle capture. When used in TTL mode together with a compatible TTL converter, your camera will meter the scene and adjust strobe power automatically.
