Product Description

The Sea & Sea YS-D2 Underwater DS-TTL Strobe offers exclusive features like no other strobe in the world. Keeping with the same great performance specs as the Sea & Sea YS-D1, the Sea & Sea YS-D2 Strobe has added Audible Confirmation providing TTL confirmation and ready light confirmation. The Sea and Sea YS-D2 also features a rear glowing panel with easy to read controls.

The Sea & Sea YS-D2 is the most versatile underwater strobe available today. A true all rounder, it works in most underwater scenarios and with any camera or housing. It can be synced to a camera's pop-up flash, hot shoe or TTL connector with electric or fibre-optic cables and used with any TTL protocol.

The backlit display with colour coded modes and its sheer simplicity in use are genius. The size and weight make it a winner for the travelling underwater photographer.

New Features: (different than YS-D1)

  • Audible confirmation
  • Glowing control panel
  • New control knobs
  • Dual powered target light with red filters
  • Wing-nut style fixing bolt (YS mount)
  • Newly designed battery compartment
  • Improved Recycle Time (full): 1.5 seconds with Ni-Mh batteries (YS-D1 is 1.9 sec)

The DS-TTL exposure compensation function enables subtle lighting control by adjusting the Light Level dial in DS-TTL mode.

Powered by only four AA batteries, the YS-D2 offers a maximum light output of Guide Number 32.

Its even and flat beam is suitable and powerful enough for professional use. Not only is the YS-D2 suitable for wide-angle photography, it is also ideal for macro photography which requires delicate light level control. The strobe's guide number can be reduced to 1. Highly versatile, the YS-D2 offers more automatic and manual control over lighting to get that perfect exposure. The YS-D2 is the most versatile underwater strobe available today. The DS-TTL exposure compensation function enables subtle lighting control by adjusting the Light Level Dial in DS-TTL mode.

TTL with exposure compensation (EV) control function.

By controlling the actual flash light level, the strobe realises accurate exposure compensation with EV value. Regardless of a compact or a SLR camera, you can achieve any desired exposure compensation. However, many TTL systems are not reliable. The YS-D2’s DS-TTL exposure compensation function allows users to adjust the light level in TTL mode (-1.5EV, -1EV, -0.7EV, -0.3EV, +0.3EV, +0.7EV, +1EV, +1.5EV).

Two Accessory Diffusers

In macro photography when a wide beam is not necessary, no diffuser should be attached. When both strong light output and a relatively wide beam are necessary, the diffuser 100 should be attached. When a wide-angle lens is used, the diffuser 120 should be attached. Three beam angles can be selected in accordance with the photographers's requirements.

Ergonomic Design

The Sea & Sea YS-D2 Strobe will auto-sense when a sync cord is connected, causing the slave ON/OFF switch to no longer be active. Simple controls and configuration enables easy operation. The light level control clicks to aid in setting and operation.
