Sea & Sea Underwater Strobe YS-D3 MK II Lightning

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.
