cNODE MiniS 34-180 and cNODE MiniS 34-40V

Kongsberg Maritimes cNODE MiniS Transponder, the most advanced HiPAP mini SSBL and LBL transponder developed to date. The cNODE MiniS, with an impressive range of features, 500+ Cymbal digital acoustic channels and backwards compatibility, supersedes the Mini MST.

The cNODE MiniS transponders are the smallest members of the cNODE series. These are used with HiPAP, cPAP and μPAP systems in underwater positioning and are ideal for positioning of ROVs. The MiniS also operate with data telemetry.
