Congrats Vladimir on the pictures!
Your second wreck picture and the ray are just fantastic!
Great to see your split with 4 inch dome too :-)
And that's why i keep hoping (and asking) for Nauticam to offer hand-straps on their DSLR housings, just like Subal does, or just like Nauticam themselves do on their Mirorless housing, see this item which i had on my mirorless housing:
I think it would take your hand pain away, and provide the usual benefits of hand-straps.
I take also this opportunity to ask if anyone knows why their is some sort of buckle/shackle on the steel thing which hold the right handle of the Nauticam housing together with the main housing body, see the picture attached.
Despite attaching a hand-strap, i can't think of other possible needs?
I am happy to say my prayers apparently got heard: you can find on Nauticam dealers what seems to be a new hand strap compatible with some housings, including the D500 one!! It goes by:
Hand Strap for 28113 Large Handles (for NA-1DXII, D500, D5, 80D)
