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.

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. By using a snoot, the light surrounding the subject is cut off and only the subject is brought into view.

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.

The YS-01 underwater flash from Seas&Seas, the best-selling flash unit in its class, has been redesigned and now has improved performance. Same DS-TTL ll control as the high-quality Sea&Sea models The DS-TTL ll control circuit helps to automatically emit the correct amount of light based on the light intensity of the camera's built-in flash. The flash allows you to set the light intensity stronger or weaker than the programmed standard exposure. This feature allows even an inexperienced underwater photographer to instinctively control the amount of light they want. Example: If you are using two YS-01 Solis flash units, one on the right and one on the left, and there are white soft corals on the right of your photographic subject, you can subtly reduce the light intensity of the flash unit on the right alone by simply setting the brightness control to minus. With the improved circuitry, you can achieve the desired lighting for all your underwater shots in no time at all. Increased light intensity from the pilot light Compared to the previous model, the light intensity of the focus light of the YS-01 Solis is 40 percent stronger, which has improved the visibility of the light beam and helps you to judge the position of the flash more accurately. Superior light distribution and wide beam angle Due to the exclusively developed prismatic lens, the YS-01 Solis realises a wide beam angle of 100°x 100° with an ideal flat light distribution, even when the accessory diffuser is not attached. With the diffuser, the light becomes softer and the beam angle increases to 110°x 110°.

Replacement for the diffuser included with the flash.
