Sea & Sea YS-D3 MKII

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.
