The Type 7970 Super Sub-Mini is designed for deepwater applications up to 4,000 metres and has a highpower directional transducer with an acoustic output comparable to Sonardyne's most powerful Compatt transponders. 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. The unit's 'bilingual personality' mode automatically senses the type of positioning system interrogating it and switches mode accordingly. Key features • Depth telemetry capability with choice of 2,000 or 4,000 Metre rated sensors • 1,000 Metre rated SSM also available • Directional transducer with class leading acoustic power output • Channel selection via dual external controls or serial data port by PC • Long-life, fast charging NiMH battery • Compact and rugged design • Windows based software for test and setup In addition, Super Sub-Minis now support more Sonardyne frequencies and all HPR 300 and HiPAP® channels. The Type 7970 is available with either 2,000 metre or 4,000 metre rated depth sensors. 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 Transmit Source Level (dB re 1µPa @1m) Receive Sensitivity (dB re 1µPa) Quiescent Life Maximum Update Period Number of Replies Responder Transponder Depth Telemetry Power Supply Mechanical Construction Dimensions (LxDia) Weight in Air Weight in Water Ordering Information Type Type Type Type 7970-000-01 7970-000-02 7970-054 7972 SSM Type 7970 (2,000 Metre Version) 2,000 Metres MF (19-36kHZ) +/-45º (-10dB), +/-30º (-6dB), +/-20º 202dB
