I read and see people talking about rebreathers that have many hours of dive time. But what if you wanted a scrubber that was as small as possible and you were happy with a 60 minute max dive? To ensure enough dwell time at the end of the dive, how many KG of sorb would be needed?

Follow up question, what is the smallest canistor on the market and what is the advertised dive time?
