Check out our Sea & Sea YS-D3 Review at Bluewater Photo and the YS-D3 Review on the Underwater Photography Guide

The Sea & Sea YS-D3 is one of the world's best strobes for underwater photography. It offers lots of great improvements from it predecessor, the YS-D2J, including quicker recycling times, a more even beam, a redesigned back display, and a more powerful targeting light. The YS-D3's circuitry has been improved and the strobe is capable of a powerful, professional guide number of 33 (land). At guide number 22, the YS-D3's recycling time is a mere 0.6 seconds and at guide number 16, there is virtually no recycle time! This kind of capability is very beneficial to underwater photographers that need to shoot quick subjects with burst modes on their camera.

What's New With The Mark II:

The original Sea & Sea YS-D3 strobe has been upgraded to the Sea & Sea YS-D3 Mk II. Both strobes are essentially the same with a few minor diferences. 

  • The Mark II features enhanced TTL shooting with better third-party optical TTL converter compatibility
  • New compatiblity with existing and older Sea & Sea optical TTL converters
  • Improved TTL with compact cameras
  • Redesign of the light intensity adjustment dial and mode switch for better ergonomics

Optional Accessories for the Sea & Sea YS-D3:

It's pretty clear to us that when Sea & Sea was designing the YS-D3, they were addressing every concern they've ever heard about their strobes. Many of these concerns were answered in the form of strobe accessories that make our mouths water! We might just be seeing a golden age of innovation for Sea & Sea. Check out some of our favorite accessories for the YS-D3:


1. Sea & Sea YS-D3 Snoot - the YS-D3 snoot will allow you to produce dramatic lighting and capture beautiful black backgrounds easily with your YS-D3. It has a prism built in so that the target light of the strobe will easily illuminate the subject. 



2. Sea & Sea YS-D3 Dome Diffuser - the dome diffuser for the YS-D3 produces a nice, even, 150 degree beam. This is great for wide angle photography, especially with a fisheye lens.

3. Sea & Sea YS-D3 Slave Prism - The slave prism allows the strobe to be triggered remotely without any cords or cables. This is great for backlighting wrecks, caves, and reefscapes.



4. Sea & Sea YS-D3 Strobe Diagonal Ball Mount - The diagonal ball mount has a 35 degree inclination which minimizes interference between the sync cord and ball mount.
