+amount of breathing gas is released every time the breather inhales. With
+active SCR (aSCR) equipment, in contrast, a small amount of breathing gas is
+released continuously from the back cylinder.
+
+To log pSCR dives, no special procedures are required, just the normal steps
+outlined above:
+
+- Select pSCR in the _Dive Mode_ dropdown list on the *Info* panel.
+
+- pSCR diving often involves gas changes, requiring an additional cylinder.
+  Define all the appropriate cylinders as described above and indicate the
+  cylinder/gas changes as described above in the section on
+  xref:S_MulticylinderDives[multicylinder dives].
+
+If a pSCR _Dive Mode_ has been selected, the dive ceiling for pSCR dives is
+adjusted for the oxygen drop across the mouthpiece which often requires
+longer decompression periods. Below is a dive profile of a pSCR dive using
+EAN36 on the back cylinder and oxygen for decompression. Note that this dive
+lasted over two hours.
