What's in the box: DS51 strobe, Diffuser, Waterproof bulkhead cap, Silicone lubricant 1cc tube
The size and weight of the DS51 make it the perfect choice for the traveling underwater photographer. The DS51's intensity and angle of coverage are comparable to any strobe in its class. The strobe can easily switch between TTL/Auto and any of the six manual power settings through a large, easy-to-turn dial on the rear of the strobe. A simple battery door is easy to remove and replace and provides a clear view of the o-ring seal. The strobe's battery compartment is independently sealed from the electronics preventing further damage in the event of a flood.
When combined with a compatible Ikelite TTL system or film TTL system, the DS51 automatically adjusts brightness to provide perfect exposure whether you're shooting macro, portrait or wide angle.
