Sea & Sea YS-D3 Strobe

Creating a broad evenly distributed light intensity and a wide beam angle for the ultimate underwater image.

  • 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)


    In order to avoid misunderstanding, the YS-D3 guide number (GN) and the beam angle are based on measurements taken on land (not underwater) 
    Some competitors will often state a GN measured on land and the beam angle in water, for example a GN 33 and beam angle of 110 degrees. However, this GN 33 value is based on a beam angle of 60~70 degrees. The beam angle may be expanded in water by a dome effect, however the GN in water is significantly lower than the value measured on land. 
     
    Note: A land-based strobe that uses the same four AA batteries as the YS-D3 may provide a notation that the GN is 60, but these measurements are taken under the condition that the focal length is equivalent to 200 mm (= beam angle 12 °). When the beam angle becomes narrower, the brightness of the illuminated area increases due to the light-collecting effect.
     

    Aspherical optical troidal lens
  • 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)
