Would I change anything? Of course. Someday I'll add a shut-off for the mouthpiece to prevent flooding when it's not in use. The breathing hoses could use a little weight so they don't pull so much. The schematic and circuit boards could use some refinement. A secondary PO2 display based on the sensor voltage would be nice. Acrylic (polymethylmethacrylate, i.e. plexiglas) is a no-no for absorbent canisters, but Lexan (polycarbonate) seems OK, etc, etc, etc.
I'm into my 3rd year diving this unit. PO2 has been
against a Ceramatech "Handi" oxygen sensor. Overall, I'm pretty pleased.
