Kongsberg 1171-Series Scanning Sonar

High Resolution, Multi-frequency Fan/Cone Beam Transducer with Tilt Block and Internal Compass

This 1171-series sonar head uses new transducer construction techniques optimized to provide low noise, high-resolution sonar operation at frequencies from 600 kHz to 1.5 MHz. This wide-frequency, dual transducer configuration is ideal for both imaging and profiling applications where data clarity supersedes any other requirement at operating ranges from 25 m out to more than 150 m. This 1171 sonar head is well suited for bottom clearance, body recovery, underwater construction support, pipeline and cable surveys, bridge and pier inspection applications. The open face transducer design is ideal for all water temperatures, and the beam pattern is not affected by thermal defocusing. The adjustable tilt block allows the operator to mechanically set the transducer tilt up to +/- 30°, as required for optimal imaging data acquisition. In addition to heading information, the internal compass module also provides pitch and roll information. This sonar head is operated using the MS 1000 software.
