I have an Aquatica A300 housing for sale for a Nikon D300.
Interestingly I also have an additional housing back for a Nikon D200 that Aquatica made up for me so I could use my D200 as a back up body if I got stuck in the field. Its never been wet as I never needed it but its a great option that goes with the D300 housing too.
I also have a 60 Macro port that honestly has been used only once. (I have many bespoke macro ports that I use instead).
I have a zoom gear for the Tok 10-17 that I'll let go too.
All the gear is very clean and well maintained.
PM me and I'll send on images.
The D300 housing & D200 back is USD 1100.00 and the Port is USD 300.00 plus shipping.
Thanks Folks, N.
