Technical Specs

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-degrees by attaching the standard accessories diffuser. When the optional dome diffuser (see SKU: SSDD140) is attached, beam angle will increase to as wide as 150-degrees (TBD).

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 7.87"/200mm (equal beam angle 12-degrees). When the beam angle becomes narrower, the brightness of the illuminated area increases due to the light-collecting effect.

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. Snoot (optional accessory see SKU: SSYD3SN). A strobe adaptor which narrows the beam angle to be directed at a target point. Diameter of the opening 0.98" (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. 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. Traditional YS base. Easy vertical swing. Diagonal ball base (only for YS-D3). A ball base inclined at 35-degrees 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.

The YS-D3 has a guide number (ISO 100/m) land: 33, 28 (with diffuser attached). Beam angle: 80-degrees x 105-degrees (without diffuser), 100-degrees x 110-degrees (with diffuser). The YS-D3 is powered by 4x AA alkaline batteries 6V or 4x AA Ni-MH batteries 4.8V, with number of flashes 140 with alkaline and 220 with Ni-MH. Recycle time (full) with alkaline 3.5 sec. and 1.7 sec. with Ni-MH. The strobes color temperature is 5800-degrees K and with the diffuser 5500-degrees K. The depth rating of the strobe is 330' (100m). The unit measures (W x H x D) 3.6" x 4.4" x 5.8" (92mm x 11mm x 147mm), excluding ball base and weighs 21.5 oz. (610 g) without batteries and ball mount. Underwater buoyancy is approximately negative 0.7 oz. (negative 20 g) with batteries and ball base. The YS-D3 exposure control is DS-TTL II, Slave TTL, Light level control dial (GN): 1 / 1.4 / 2 / 2.8 /4 / 5.6 /8 / 11 / 16 / 22 / 33 (11 steps). Strobes auto power off function is 30-minutes, sync cord connection is a 5-pin Sync cord/N and is compatible with a fiber-optic cable. The strobe has an over-pressure relief valve, LED target light (output is adjustable in 2 steps), and audible charge signal. The YS-D3 Strobe comes complete with a diffuser, ball mount, and tube of silicone grease.
