    Features
    • Excellent night-time visibility. The illuminated control panel is ideal for night diving
      Color of illumination changes to indicate mode: aqua blue (in DS-TTL mode), blue (in slave TTL mode), orange (in manual pre-flash mode) and Green (in manual mode without pre-flash). You can check which mode the strobe is set even under pitch-black conditions.

      In manual pre-flash mode

      In manual non pre-flash mode
    • Maximum guide number is a powerful 32 (ISO 100, meter). Recycle time is only 1.5 sec(*1)
      The YS-D2 is powerful enough to illuminate a wide area, even under very bright conditions with plenty of natural sunlight. During macro photography, where subtle exposure control is required, manual mode can easily be selected and the guide number quickly adjusted as low as 1.
      (*1) when nickel hydride AA batteries are used.
    • DS-TTL ll automatic exposure control with improved accuracy and stability
      SEA&SEA’s own automatic exposure control system, DS-TTL ll, has been further improved. Tuning light emitting timing in detail and adding light emission detection function, the accuracy of automatic TTL exposure has been noticeably improved. Previously, TTL photography was difficult with the lens’s aperture wide-open (maximum aperture) and images were likely to be overexposed. It is now possible to give a low powered flash so the correct exposure can be easily achieved with the YS-D2.

      In DS-TTL II mode
    • EV control function can finely tune the amount of light emitted
      By controlling the actual flash light level, the strobe achieves accurate exposure compensation with EV compensation. As the exposure compensation range has improved to +/- 2.0 EV, users can concentrate on shooting even more creative images. (-2,0EV, -1.5EV, -1EV, -0.7EV, -0.3EV, +0.3EV, +0.7EV, +1EV, +1.5EV, +2.0EV).
    • Two diffusers and red filters included with the strobe as standard
      By attaching one of the included diffusers, the beam angle is increased to 100o or 120o (circular) with a soft and even light. The red target light filter helps avoid disturbing skittish creatures that are likely to react to normal light. The red filter is fitted inside the diffusers.

    • The target light can be adjusted in 2 steps
      The strobe is equipped with a target light (approximately 100/300 lumen). In use (target light switch in ON position), the light will be automatically turn off when the strobe fires and will automatically turn back ON after 0.5 sec.
    • Ergonomically improved controls
      Handling is greatly improved. Larger knobs and a new magnetic rotary switch help prevent controls being accidentally reset in use. With the new controls, quick operation is possible when photo opportunities suddenly appear.
    • Custom mode is a new innovation which allows the YS-D2 to be compatible with cameras with non-standard pre-flash settings
      Some manufactures use their own pre-flash timings on their cameras. The new custom function means the YS-D2 can be compatible with cameras with non-standard pre-flash in DS-TTLII and manual modes.
    • Attaching the YS-D2
      The strobe can be attached to an arm with the Ball-mount (included) or YS-mount(optional)

    • Choosing the right cable
      In accordance with the camera and housing you use, choose either a fiber-optic cable (optional) or sync cord (optional) to connect the strobe.
      * A Fiber-optic cable ll is required to use the DS-TTL ll function.

      * When the YS-D2 is used with a camera with built-in flash in housing, use the Fiber-Optic Cable.
      * Use of genuine SEA&SEA Fiber-Optic Cables is recommended. SEA&SEA strobes may not function properly if a third-party Fiber-Optic Cables are used (functions such as TTL auto exposure in particular).

      CAUTION
      Do not use non-recommended batteries (such as lithium primary batteries). Use of non-recommended batteries may cause battery leakage and overheating and may cause the strobe to rupture, which could result in personal injury.
