How is a Sentinel different from other rebreathers?
All of the major rebreather models are good quality units. There is no perfect rebreather; they all have strengths and weaknesses that make each uniquely more or less suited to your needs. Beyond the features of the rebreather itself, you should consider the supplier along with how the model was designed and has been supported. Only a very few rebreather models are supplied by large and well-established dive equipment companies, and the Sentinel is the only rebreather where the electronics system has been developed by a leading dive computer company.
