[Features]

• Highly accurate DS-TTL dimming
  • DS-TTL dimming accuracy has been greatly improved by adopting a newly designed light receiving sensor.
  • By applying detailed custom settings, it can be used with high accuracy with a wide variety of cameras of multiple brands.
• Manual mode has 11 steps.
  • In manual mode, light intensity can be adjusted in 11 steps. The settings are (GN: 1 / 1.4 / 2 / 2.8 / 4 / 5.6 / 8 / 11 / 16 / 22 / 33). The value can be easily seen on the scale on the light intensity adjustment dial. Compatible with digital cameras that do not have a pre-flash function.
• High light intensity GN33
  
  • The light output has a guide number (GN) of 33, one of the highest among general-purpose underwater strobes. The use of two discharge tubes increases power and achieves GN 33 at full flashing.
• Various accessories available for all underwater imaging experiences
  
  • ・Dome diffuser (optional accessory)
    
    • Increases beam angle to 170°×150° Essential accessory when fisheye lens is used, or soft light is required.
    • + Guide number will drop to -1.5EV when it is fitted.
  • ・Snoot (optional accessory)
    
    • A strobe adaptor which narrows the beam angle to be directed at a target point. Diameter of the opening 25mm. Designed with internal prism which aligns target light`s light axis and strobe`s light axis to the center.
  • ・Slave prism   (optional accessory)
    
    • Optical guiding device to fire the strobe when a fiber-optic cable is not used. This device is for manual use only. The device is effective if multiple strobes are used in a fixed position.  However, the flash may not fire depending on the position of where multiple flashes are occurring in relation to that of the master flash.
• Excellent visibility
  
  • The indicator color changes each time the mode switch is repositioned. Blue (in DS-TTLII mode), red (in RC mode), yellow (in manual mode with pre-flash), and green (in manual mode without pre-flash) are the different colors for identification, so positioning of the controls is easy to see even when night diving.

Connection method with arm that can be selected according to preference

• YS base (common to YS-D1 / D2 / D3)
• Diagonal ball base (only for YS-D3)
