I'm selling my pair of Sea & Sea YS Auto/Duo, as shown in pictures.
They never flooded, work perfectly, but cosmetically they show some signs of wear.
I'm including a set of spare o-rings, and the diffusers.
Currently they have kind of velcro near the optic sensor because they were used with a compact camera. I can include the home made optical adaptors, or you can easily remove the velcro, if you'll be using electric cables.
The strobes are located in Lisbon, Portugal.
Asking 350€ plus shipment.
I prefer wire transfer, but Paypal is also OK.
