I have two Sea and Sea YS-D1 strobes for sale. Both strobes have been used but are in great condition--photos of actual strobes shown below. Both strobes function perfectly and have no damage.
All parts for both YS and ball mount and both 100 and 120 degree diffusers included with both strobes. Also included two sets of new o-rings and Sea and Sea lube for each strobe and a fiber optic cable for each strobe.
Strobes are $275 each, or I will sell both together for $525. Free shipping included in the continental United States. Will discuss shipping costs for other locations. If you have any questions, please message me. Thanks.
