Products:

SIVA S-10
A closed circuit chest mounted apparatus using 100% oxygen developed specifically for Special Forces operations and shallow water MCM.

SIVA S-24
A chest mounted apparatus for closed circuit operations using 100% oxygen and/or premixed oxygen-nitrogen gases in a semi-closed mode to 24 meters. The S-24 is used for both MCM and Special Forces operations.

SIVA-55
A conventional semi-closed circuit rebreather using pre-mixed gas for MCM operations to 55 meters with the capability of closed circuit oxygen operations. SIVA-55 may be converted to the SIVA + configuration via a modular upgrade kit.

SIVA +
A semi-closed circuit mixed gas rebreather that mixes oxygen and either nitrogen or helium to deliver gas to the diver at a constant partial pressure of oxygen to a depth of 90 meters for MCM operations.
