Wow, that seems really low. 90 cu ft/hr is 1.5 cu ft/min divided by 3 people is 0.5 cu ft/min/person. That's one fourth of what NOAA recommends for a person at rest.
Apparently the Sport Sub design has evolved since I did my research on it. You say there's a rebreather of sorts? Can you define the sorts? Do they use a CO2 absorbent?
Also, are you familiar with how the automatic ballast system works? I have not been able to find any information on it.
Thanks...
