Following latest features of the Z-330 strobe, the D-200 is designed to deliver maximum G.N. 20 and focus on optical trigger system. Built-in dome lens is optically designed to offer wide 110 degree coverage underwater without any diffuser which can sacrifice power. High performance, multi-function and friendly handling with lightest underwater weight supports your underwater photography with superior performance.
Expanded Underwater Coverage 110 degree by Dome Lens
Precisely designed front dome lens (*1) together with INON's unique patented T-shape Twin Flash successfully manages both powerful G.N. 20 (*2) and circular 110 degree coverage UNDERWATER without sacrificing any power. Without using a diffuser, the D-200 strobe is well designed to deliver high power and wide coverage.
Not as like a conventional translucent diffuser which can widen coverage while it blocks some power and stores heat inside, this specially designed dome lens diffuses light thanks to reflection ratio of air, acrylic and water to attain UNDERWATER coverage 110 degree with almost all powerful output coming through.
Furthermore, the D-200 has overcame drawback of high-power strobe which has long flash duration and reaches to FULL power after start flashing in significantly short period of time.
Together with flashing system in sync with pre-flash and main flash of camera’s built-in flash, the D-200 can deliver full power even at 1/1000 high shutter speed setting without cutting power.

Easy to Handle Underwater, Buoyant at 4g
The D-200 strobe provides buoyancy at 4g (*3) underwater including 4 x AA eneloop batteries and Strobe Light Shade making the strobe slightly buoyant underwater. By attaching an adapter such as Z Adapter MV or Z Joint can have almost neutral buoyancy in salt water. A heavy underwater weight strobe may cause sudden strobe movement with its own weight when unclamping too much while neutrally buoyant D-200 offers comfortable strobe aiming adjustment as well as easy handling underwater.
(*3) Buoyancy measured in freshwater is about 4g/0.1oz. Calculated buoyancy in sea water is about 23g/0.8oz. Including 4 x eneloop batteries and Strobe Light Shade.
