Sharkpixie 0 Posted November 28, 2015 For sale is a Nauticam 4.33" acrylic dome port for mirrorless housings. I bought this as a backup port and never used it. Upgrading to a different port now, so I don't need this as a backup anymore. Comes with original box, new o-ring, and neoprene port cover. Retail price is $495. Selling mine for $395. Buyer pays shipping. Share this post Link to post Share on other sites
