The SeaFrogs SR-009 is a rechargeable manual flash trigger for compatible underwater photography systems using fiber optic strobe connections. It converts the camera's hot-shoe signal into optical pulses that trigger an external strobe through a fiber optic cable.
The updated version features USB-C charging, a 3.7V 300mAh lithium-polymer battery, more than 600 flashes per full charge, over 5 hours of continuous operation and a 0.3-second recycle time.
TTL automatic flash exposure is not supported. Flash output must be adjusted manually on the external strobe. Before ordering, confirm the housing's internal clearance, hot-shoe position, fiber-optic port alignment and strobe compatibility.
