Underwater Flash IKELITE DS 51
This powerful Flash is ideal for all types of photographers, beginner as professionals.
Its unique mode-setting dial makes it an easy-to-take flash. The switch between TTL mode, full power manual mode and the 5 intermediate exposure power modes are immediately accessible.
Its rear compartment sealed battery door is transparent and allows to see easily the O-ring to check the good sealing of the assembly.
The battery compartment is completely disconnected from the electronics compartment to avoid damage to the electronics and the flash tube during a possible drowning of the battery compartment.
A TTL exposure mode
When the flash is combined with an Ikelite subwoofer equipped with TTL electronics, the flash automatically adjusts the exposure to capture your macro shots or snapshots.

The guide number of a flash corresponds to the intensity of illumination at the center of the beam. many flash manufacturers choose to use a reflector that focuses the beam at its center to artificially increase the guide number of the flash. Ikelite chose to "sacrifice" the guide number very lightly in order to favor a soft, homogeneous image without hot spot.
Most underwater flash manufacturers indicate in their flash characteristics a maximum beam angle and not a coverage angle. The average coverage of a submarine flash is generally narrower than that indicated (average between 55 and 70 °). The coverage angle of Ikelite flashes is therefore well above average.
