Sea&Sea YS-D3 DUO DS-TTL RC strobe - WHITE

Sea & Sea YS-D3 DUO DS-TTL RC Underwater Strobe

Key Features:

• OM SYSTEM RC Flash System Compatible: Evolves with the RC mode for precise light control.
• Wireless RC Flash System: Compatible with OM SYSTEM digital cameras, offering automatic flash output control based on in-lens brightness.
• Precise Light Control: Offers better flash control compared to traditional TTL modes by using a digital optical signal for more accurate output adjustments.

High-Performance Strobe

• Powerful Guide Number: With newly designed circuitry, the YS-D3 DUO produces a powerful guide number of 33, ensuring optimal lighting performance.
• Aspherical Optical Lens: A high-precision lens ensures an even light distribution from the center to the edge of the beam.
• Wide Beam Angle: The strobe features an 80°x105° beam angle (without diffuser) and 100°x110° (with diffuser), with a 150° beam angle achievable with the optional Dome diffuser.

Important Notes:

• Guide number and beam angle measurements are based on land tests.
• The strobe’s guide number is based on a beam angle of 60-70° in land conditions, and underwater measurements may vary.

Accessories to Enhance Your Underwater Photography:

• Snoot (Optional Accessory): Narrows the beam angle to direct light precisely onto the target, ideal for focused lighting.
• Dome Diffuser (Optional Accessory): Increases the beam angle to 150°x170°, essential for fisheye lenses or soft light effects. Guide number drops by -1.5EV with the diffuser attached.
• Flash Prism (Optional Accessory): Enables strobe firing without fiber-optic cables for manual use, particularly useful when multiple strobes are deployed in fixed positions.

Visibility and Ease of Use

• Backlight Panel: The YS-D3 features a color-changing indicator on its back for clear mode identification:
  • Blue (DS-TTLII mode)
  • Red (RC mode)
  • Yellow (Manual mode with pre-flash)
  • Green (Manual mode without pre-flash)

This ensures visibility even in low-light conditions, perfect for night diving.

Flexible Arm Connection Options:

• The YS-D3 comes with a straight-type ball base but can be adapted to the YS base (compatible with YS-D1, D2, D3) or the Diagonal ball base (exclusive to YS-DUO/D3) for enhanced flexibility and ease of positioning.
