Switched over to Nikon for U/W work now, so some surplus gear if anyone fancies some bargains!
Nauticam 1dx housing. Fully functional, never flooded, 2 minor issues. First, the shutter release doesn't return after a shot is taken, probably just a missing spring, has no effect in real life. Secondly, the housing comes with the vacuum valve and electronics. The valve is stuck so to release the pressure, you need to twist all the valve as if you were going to unscrew it. It is still 100% functional. Handles included, obviously ! £1100
Macro port 94 for the 100mmL macro - excellent condition - £250
Nauticam TTL flash trigger, a few light rub marks, nothing major - £300
