I have a barely used Nauticam adapter for Aquatica ports.
This enables you to use any Aquatica Bayonet Port on a Nauticam Housing.
I purchased this to use my 8" Aquatica Dome but after a few weeks decided to puchase the Nauticam White Balance Dome.
Adapter includes back cover.
The adapter has seen very little use and is in as new condition.
No damage at all.
RRP is $240
Happy to take US$160 plus postage and fees (postage from Australia to the US would be about $20)
