Sea & Sea YS-D3 Duo Review

SEA & SEA YS-D3 DUO UNDERWATER STROBE REVIEW

The Sea & Sea YS-D3 Duo is the latest strobe model, and it comes with a few new features compared to its predecessor, the YS-D3. The most significant change is that the Sea and Sea YS-D3 Duo now supports Olympus and OM System RC Automatic TTL Flash Power. This is great news for those who use TG, Pen, and OM cameras. If you already have a YS-D3, the power and beam pattern are the same, so if you are not using an Olympus or OM camera, there is no difference in performance.

At Backscatter, we take the testing of strobes very seriously in order to provide our customers with the most accurate comparison between different models. As there isn't any industry standard for measuring strobe performance, we rely on our in-house testing process. Our testing process includes underwater testing of the strobe's guide number and beam pattern using a professional light meter inside a custom-made housing. We also conduct on-land testing of the strobe's color temperature, recycle time, and flash duration using a light meter and a spectrophotometer in a controlled environment. With this information, we are able to compare all of the strobes we sell on an even playing field.
