To clarify the connection between the KISS GEM and the Shearwater dive computer.
When applied to a KISS fully closed (CCR) rebreather like the Sport, Classic or Explorer, the computer reads the three oxygen cells in the CCR. Connection between the cells and and computer is carried out by a single cable that is Hard wired to the CCR (inside the scrubber head, the cable is split off with two wires running to each 02 sensor) with the other end, via a fischer connecter is plugged into the shearwater computer on your wrist.
That is the general configuration on a CCR.
With the GEM (a semi-closed rebreather - SCR) the same Shearwater computer (placed in SCR mode) is connected via a fischer cable just like the one in the CCR, with one exception that it is only going to read one cell, which is all that is needed with the GEM, to monitor your PO2 and FO2, which it applies the information into the computer’s algorithm during the course of the dive.
While certainly not dainty on the wrist, the Shearwater is great computer, in addition to using the Predator model with my KISS Explorer, I use it for extended range open circuit dives and now will be using on my GEM when I receive it next month.
Now, if you think the Shearwater computer is not for you, or at the moment a little pricey for your wallet, the GEM works perfectly fine using the standard KISS PO2 display monitor (which you can replace with fischer cable later) and your current Nitrox computer. After all, when diving SCR, you are pretty much diving a single FO2 percentage (give or take 3%) the entire time.
