The unit's 'bilingual personality' mode automatically senses the type of positioning system interrogating it and switches mode accordingly. In addition, Super Sub-Minis now support more Sonardyne frequencies and all HPR 300 and HiPAP® channels. Key features • Depth telemetry capability with 1,000 Metre rated sensor • 2,000 Metre and 4,000 Metre SSMs also available (Type 7970) • Directional Beamshape with class leading acoustic power output • Channel selection via dual external controls or serial data port by PC • Long-life, fast charging NiMH battery • Optional remote transducer • Provides greater flexibility when deciding where to install unit on vehicle • Ideal for small ROVs and towfish The Type 7973 Super Sub-Mini is depth rated to 1,000 metres and has an omni-directional beam pattern that gives a wide area of acoustic coverage. Options for the Type 7973 SSM include a remote transducer that provides added flexibility when sitting the unit on smaller vehicles and a floatation collar to enable seabed deployment. For improved positioning accuracy, a built-in pressure transducer provides depth; this can be telemetered to Sonardyne's USBL systems as part of the positioning cycle. A dual external channel selection control, or serial data link, allows the SSM to be used with all of the popular acoustic navigation systems. Sonardyne UK (Head Office) T. +44 (0) 1252 872288 F. +44 (0) 1252 876100 E. sales@sonardyne.com www.sonardyne.com Specifications Super Sub Mini Transponder/Responder (SSM) Feature Depth Rating Operating Frequency Transducer Beamshape Operating Channels Transmit Source level (dB re 1µPa @1M) Receive Sensitivity (dB re 1µPa) Number of Replies Responder Transponder Depth Telemetry Maximum Update Period Power Supply Quiescent Life Mating Connections (Bulkhead) Mechanical Construction Dimensions (LxDia) Weight in Air Weight in Water Options and Accessories Type 7973 1,000 Metres MF (19-36kHz) Omni-Directional All Sonardyne and HPR 300 / 400 Channels, HiPAP Channels B12-B87 190dB
