Zen Underwater DP-230 230mm Fisheye Dome Port for Nauticam

Description

DP-230 230mm Fisheye Dome Port
I purchased this used and had great time using it.  I've since sold my underwater camera setup and this is the last item I have left.  I would recommend having it serviced or servicing it yourself before using.  It does come with a Nauticam rear cover and a neoprene cover.  There are no scratches or imperfections in the glass that I can see.  There is some paint / decal scuffs which is documented in the pictures.  This is the older version of the Dome Port and is rated for 65 meters.
Shipping will be via USPS Priority Mail and insured for the full retail amount.  I will cover both of these costs.
Due to the type of item and the hobby that it is associated with, it is sold as is with no warranty implied or offered.
