I have a variety of Nauticam gear to sell, I inherited it from a family member who passed away. I do my own underwater photography, but not in the ocean and not as a diver (mine is portrait work at the moment and I use Ikelite). So I'll try to answer questions, but my knowledge is limited.
2 YS-D1 strobes with caps, some minor wear, never flooded and tested recently - works great. Willing to post a video upon request.
2 sync cords
2 cloth protectors
Ultralight accessories - fair condition with erosion on some. I'll post more pictures if requested - they are still useful, but not like-new.
This was used with a Nauticam dslr housing

This dome is in fair/good condition, still very functional, but has scuffs and minor defects. The seal is new, but I recommend replacing it for peace of mind.
Extension ring is in good condition with a new seal (I recommend replacing it for peace of mind).
Great condition, looks new.
This eye piece is in good condition with regular wear. The rubber around the eye moulding has a tiny crack, but doesn't effect the usefulness (see picture).
Misc. items - including the compass (pictured together)
Make an offer
The compass is glued to one of the balls for an ultralight arm

Nauticam Housing for Canon 5D Mark III
Make an offer
The inside is pristine! But it's missing an eyepiece (unless you purchase the 180 viewfinder)
The outside is corroded, needs repair. Possibly great for extra parts.
It's fully functional, I put my own Canon 5D Mark III inside and submersed it in the bathtub, there were no problems. So it could work great even though it's not pretty, but it could also be a problem later.
