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.
