SOFT Dock for Sea&Sea-YS D3

High Performance U/W-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? Various accessories available for all underwater imaging experiences Dome diffuser (optional accessory) Increases beam angle to 150°×170° 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. Flash 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. * The color in DS-TTLII mode has been changed from the YS-D2 to match the color with the optical converter. In DS-TTLII mode In manual pre-flash mode   In manual non pre-flash mode Connection method with arm that can be selected according to preference YS-D3 comes with a straight type ball base. Optional YS base and new Diagonal ball base can be installed depending on the application. YS base (common to YS-D1 / D2 / D3) Traditional YS base. Easy vertical swing. Diagonal ball base (only for YS-D3) A ball base inclined at 35 ° compared to the straight type. This makes it easier to lower the strobe backwards, making it suitable for shooting when using a dome port. Also, when a Synchro Cord N is installed, interference between the cord and the ball clamp is minimized.

NEW, YS-D3 MKII MODEL Sea&Sea has now updated its flagship YS-D3 strobe to the YS-D3MKII. The new updates enhance TTL shooting and third-party optical converter compatibility while still retaining all the great features, such as a 33 Guide Number, wide Beam Angle and broad flash distribution of the original D3 The new MKII model will be a “running change” update, that is, the product number (#03123), will remain the same. 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.

Light source This is a high-performance strobe that pursues quality of light, and its high luminous flux and wide beam angle are effective for wide-angle photography with fish-eye lenses and other wide-angle lenses. The strobe also features our proprietary light distribution technology. 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. Two discharge tubes Uniform and even light distribution The originally developed "aspherical toroidal lens" is placed in front of the light-emitting tube, and the two discharge tubes and the "aspherical toroidal lens" provide uniform and even light distribution to the periphery, making it an ideal light source for external Illumination. Aspherical optical troidal lens Adjust beam angle with diffuser The beam angle is 80°×105° without the diffuser and 100°×110° with the included diffuser for soft lighting. When the optional dome diffuser is attached, the beam angle increases to 150°×170°. The dome diffuser is effective when using a fisheye lens or when lighting with soft light (guide number is reduced by approximately -1.5 EV). Without diffuser With attached diffuser (optional) Dome diffuser installed Operability Sea&Seas particular emphasis on ease of use, especially underwater handling. The more you use it, the more you will appreciate its easy-to-turn dial, easy-to-see panel display, and good underwater balance. Large dial Underwater operation is performed with the mode switch and light intensity control dial. The large dials are non-slip and the height difference allows smooth operation even when wearing thick gloves. It is designed to stop in steps with a click-click to minimize malfunctions. Large dial Easy-to-read backlit panel 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. In DS-TTLII mode In RC mode In manual non pre-flash mode Underwater Balance YS-D3 DUO by Sea&Sea has almost zero buoyancy with the ball mount and clamp in place. Heavy underwater weight requires unexpected force to operate the clamp, but the YS-D3 DUO is unaffected by buoyancy, so operation is smooth. Even if you change the strobe position, the underwater balance of the entire housing set does not change significantly and you can feel how easy it is to handle. Two patterns of target lights The LED target light function is useful for focusing and checking the beam angle of the strobe. Choose either 300 lumens or 150 lumens depending on the situation. 300 lumen 150 lumen One-touch battery replacement The power source is AA batteries, which are widely distributed in general. Four of the same type (1.5V alkaline AA batteries and 1.2V nickel-hydrogen AA batteries). The battery box is opened and closed by a bayonet type that does not put a burden on the O-ring. It is a one-touch operation and does not require force like the screw-in type. Hook for Fiber Optics A hook for fiber-optic cable on the strobe body smartly guides the fiber-optic cable. How to connect with the arm of your choice A straight type ball base is included, but the YS base or Strobe Ball Base 35 can be attached as an option depending on the application. (optional) YS base (optional) Diagonal ball base Accessories A wide variety of accessories expand the shooting range. Snoot An adapter that turns a strobe light into a spot light. An internal prism allows the optical axis of the target light to be perfectly aligned with the optical axis of the strobe light. The beam aperture is 25mm and the use of a snoot cuts off light around the subject to make only the subject stand out. Dome diffuser Diffuser that widens the beam angle to 150° x 170°. Light intensity is reduced by approximately -1.5 EV (GN28). Flash prism Light guiding prism that can emit YS-D3 DUO light without using a fiber-optic cable; supports RC mode and manual Emission.

Makes it possible to narrow the beam area by simply placing it in front of the underwater flash. The aiming light can be switched between red and white, brightness is adjustable, aiming light off delay is adjustable. Uses a single 18350 battery that lasts for 3 hours.
