For those considering the fathom, it's getting harder and harder to beat it. Charlie's perfected hard mounted 3L suit inflation and oxygen for OW tech diving. Now you can have independent gas sources very easily. No more worrying about sharing suit and wing together. So now you've got 3 options. 1) onboard 50s with a soft mount for the oxygen (upper left unit in the photo) 2) offboard dil with onboard inflation and oxygen for sidemounting the bailout/dil (upper right unit in the photo) or 3) the new tech rig with onboard 50s, offboard suit and oxygen on really really sturdy mounts for OW trimix (unit on the ground)
