Here is the entire rig set up for macro. (The dome port would be obvious). Dual YS-D1 strobes on * and 5 inch arms with Stix floats. Kraken 3500 focus light on top. The blue strap attaches to me so I don't lose the camera underwater.

Step 1
Remove the strobes from their clamps and remove the fiber cables. Remove the focus light and its clamp.

Step 2a (macro port)
Remove the macro port and all the clamps on the strobe arms.

Step 2b (dome port)
Remove the dome port and all the clamps on the strobe arms. I put the macro port over to the right side for this picture.

Step 3b (only for dome port)
Remove the port extension from the dome port. (Macro port doesn't use an extension.)

Step 4
Pack the arm clamps inside the 90mm dome port extension to make use of otherwise wasted space.

On the right side is the bag for the 180 degree viewfinder along with the stock viewfinder.

The next step is to swap out the big 180 degree viewfinder with the small stock on shown to the lower right of the camera.

Step 5
Open the housing to remove the 180 degree viewfinder. (Remove an o-ring holding the viewfinder in place, swap in the stock viewfinder, replace o-ring.)

Step 5 (in-progress)
Here the 180 degree viewfinder has been removed. The stock viewfinder sits to the right of the 180 degree viewinder.
