Sea&Sea YS-D3 Mark II Strobe

[Description]

Sea&Sea YS-D3 Mark II Strobe

Features of the YS-D3MKII model

• Newly developed software enables compatibility with existing and previous Sea&Sea optical converters. TTL shooting with the YS-D3MKII can now be enjoyed using the YS-D2 position on the S&S optical converter.
• A newly designed circuit improves the accuracy of TTL light intensity with compact cameras and also provides greater compatibility with third-party Optical TTL converters.
• The design of the light intensity adjustment dial and mode switch has been revised for better useability in all diving environments.

The difference can be easily recognized from the outside by the MKII label on the side of the unit and the new control knobs on the rear.

Included items: Diffuser, Ball mount (straight type), Silicone grease

[Features]

• 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°by attaching the standard accessories Diffuser. When the optional Dome diffuser is attached, beam angle will increase to as wide as 150(TBD)
• Superior consecutive firing capability to capture those critical moments.
  • The YS-D3 utilizes larger capacity condensers compared with those used on competing strobes. In addition, the D3 is also equipped with a newly designed charging circuit. As a result, the YS-D3 will fire at GN16 continuously without any interval time. Even when the strobe is fired at GN22, the strobe will fire again within a mere 0.8 seconds.
  • When the YS-D3 is fired at Guide Number over 22, a two-stage ready-to-fire signals will be issued. For instance, after the strobe fires at full power of GN33, the strobe will inform you both visually and audibly when the condenser is charged to fire at GN22. Then, when the condenser is charged enough to fire at GN33, another different signal will be issued. This design allows you to release more shutters in scenes where you want to shoot as many pictures as possible, maximizing shooting intervals between scenes

• Target light with increased power
• incorporating a uniquely designed aluminum heat diffuser, the target light is now powerful enough to be used as a dive light.（About 4 times brighter than YS-D2）
• 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
  
  • 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), light blue (in slave TTL mode), orange (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.

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)
