Fantasea Line FA-1 LED Strobe Trigger

Sync up your camera and external underwater flash units with Fantasea Line's FA-1 LED Strobe Trigger. It eliminates the need for the camera's built-in flash to fire, thus extending battery life for longer shooting sessions while also decreasing lag time between shots, since you need not wait for the built-in flash to recycle. Additionally, keeping the internal flash inactive prevents heat buildup and condensation in your camera housing.
