Overall view with a stage tank:

Full rig with S40, 200 BAR, DIN, EAN50 stage tank.

It's mounted on the left side in order to allow easy long hose deployment.

Stage Tank:

This is a 200BAR, S40 (5,5 l.) DIN valve, Luxfer aluminum stage tank. Usually it's filled with EAN50 mix. I keep it oxygen service clean.

It has a small label near the neck, right hand side, with the standard filling data (EAN %, MOD and diver name), a central NITROX label and,

 

At the back bottom, where the dive buddy can easily read it, with big figures, is the MOD (Maximum Operating Depth) for 1,4 BAR of oxygen partial pressure. We use meters.

Regulator and pressure gauge:

The oxygen service regulator is a piston Scubapro MK2 first stage with a G-250 second stage. As a gauge i'm using a transmitter coupled as TD to my Uwatec Galileo SOL computer. I also have an analog gauge that can be mounted with a short, 15 cm./6 inches, HP hose and secured to the first stage body with a 3 mm. bungee loop, but I prefer the transmitter.

Heat shrink tubing for stainless steel hose clamp:

The stainless steel hose clamp (the band) is protected, against galvanic corrosion between steel and aluminum, with two pieces of heat shrink tubing.
