I have three Sea&Sea YS-D1 strobes for sale. I purchased these strobes last year and have used them on two week long vacations. One of the strobes was my backup strobe and has never been in the water. The ones that have been used were protected by a neoprene cover. None of the strobes have any problems and were never flooded. All of the strobes come with everything just as new including the box and packing materials. See the attached pictures. Buyer pays shipping and PayPal fees from Cincinnati Ohio USA.
New Strobe $575
Used Strobe $500
