POSEIDON S7EN recreational rebreather
The POSEIDONSE7EN is a recreational rebreather that features new internal electronics. This unit is now more reliable and flexible thanks to the latest generation of Firmware. The new unit has a new Configuration Utility, which allows divers more interaction with their regulators.
