The strobe
The YS-D3 DUO delivers even and uniform light distribution with a large light output of GN33. Custom settings allow the strobe to be used with high precision with a variety of cameras and shooting styles. 

DUO stands for DS-TTL function and RC function. This strobe has integrated the OM-systems remote strobe signal and can be fired remotely by OM-system camera users on land but need to be connected with an optical cable or sync cable when used underwater. Of course, it is also possible to control the amount of light by selecting flash/non-flash or by manual operation. In addition to TTL auto shooting in conjunction with the camera, the camera can also adjust the flash output compensation during TTL auto shooting.

Note

The YS-D3 DUO has an updated optical sensor that is more sensitive, this is to get a more accurate TTL dimming. What might occur is that when you turn on the strobe without an optical cable connected the strobe start to fire and the green ready light turns to yellow (saftey mode) and the strobe stops working. However, as soon as you connect an optical cable the ready light turns green again and you can use the strobe in a normal fashion again.

High Performance Strobe
Newly designed circuitry and light-emitting unit produces powerful guide number of 33. In addition, a high precision aspherical optical troidal lens has been fitted over the two flash tubes to disperse an even light from the center to the edge. The strobe's beam angle will increase to 110 degrees by attaching the standard accessories Diffuser. When the optional Dome diffuser is attached, beam angle will increase to as wide as 150 degrees.

Backlight panel that is effective when shooting in dark environments. The indicator color on the back of the YS-D3 changes each time the position of the mode switch is changed. Blue (in DS-TTLII mode), Red (in RC mode), Yellow (in manual mode with pre-flash), and Green (in manual mode without pre-flash) The positioning of the operation system is obvious during night diving.
