Is the Divesoft Liberty rebreather over-engineered?
Liberty's redundancy is intentional: the design aims to avoid a single electronic component failure disabling the complete rebreather.
What Divesoft has done with the Liberty is to design a system from the bottom up to properly engineer a rebreather to sufficiently accommodate the requirements to avoid a single component failure. Technical diving demands redundancy and backups. Previously designed rebreather platforms where unable to avoid single part failures either with gas injection with a single solenoid, or single point PO2 monitoring with using only Oxygen cells.
Technical diving with closed circuit rebreathers can be a strenuous activity but without proper equipment, it can be a dangerous sport. The Liberty rebreather is designed to be fault-tolerant, which means that no single malfunction in the electronic system can cause a catastrophic failure of the whole system rendering the unit to be un-useable.
