The YS-D3 DUO Strobe from Sea & Sea

The YS-D3 DUO is a high-specification underwater strobe with three shooting modes: DS-TTL, RC mode and manual.
The YS-D3 DUO delivers even and uniform light distribution with a large light output of GN33.
Custom settings allow the strobe to be used with high precision with a variety of cameras and shooting styles.
Shooting Modes
Highly accurate DS-TTL dimming
DS-TTL dimming accuracy has been greatly improved by adopting a newly designed light receiving sensor.
By applying detailed custom settings, it can be used with high accuracy with a wide variety of cameras of multiple brands.
The “RC System” is a flash system for OM SYSTEM digital cameras and the YS-D3 DUO was developed in collaboration with OM Digital Solutions to incorporate the RC mode.
RC mode is a light control mode in which the camera automatically controls the flash output based on the brightness through the lens. The YS-D3 DUO is equipped with a more precise “RC mode” that was developed based on system information officially provided by OM Digital Solutions. The YS-D3 DUO is equipped with a more precise “RC mode” developed based on the system information officially provided by OM Digital Solutions.
Manual mode has 11 steps
In manual mode, light intensity can be adjusted in 11 steps. The settings are (GN: 1 / 1.4 / 2 / 2.8 / 4 / 5.6 / 8 / 11 / 16 / 22 / 33). The value can be easily seen on the scale on the light intensity adjustment dial. Compatible with digital cameras that do not have a pre-flash function.
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.
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.
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.
Operability
We placed 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.
Underwater Balance
YS-D3 DUO 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.
