Kongsberg 1171 High Resolution Sonar Head Series for Real-Time Imaging in Low-Visibility Underwater Inspections
When you’re working underwater, visibility is rarely on your side. Murky water, low light, and suspended debris can turn even the simplest inspection into a guessing game. Whether you’re trying to assess structural damage, locate an object, or track progress during a project, not being able to clearly see what’s happening below the surface slows everything down and increases risk.
That’s where high resolution scanning sonar changes the game. Instead of relying on visibility, it gives you a clear, detailed picture of underwater environments in real time. You can confidently inspect structures, identify targets, and make informed decisions without sending divers into uncertain conditions or wasting time on incomplete data.
High-Resolution Imaging with Open-Face Transducer and Narrow Beam Sonar Technology
The open-face transducer design and narrow horizontal beam pattern work together to deliver consistently sharp, high-resolution sonar imagery in even the most challenging underwater conditions.
By eliminating acoustic lensing and preventing thermal defocusing, the exposed transducer ensures reliable performance across varying water temperatures without signal distortion.
Paired with increased power output and a tightly focused beam, the system achieves superior signal-to-noise ratios and finer angular resolution, allowing operators to clearly identify structural details that would otherwise be lost in turbid or near-zero visibility environments.
Versatile Mounting Options with Adjustable Tilt and Integrated Positioning Sensors
The Kongsberg 1171-Series is built for flexible deployment, allowing it to be mounted on tripods, vessel-mounted poles, or ROVs, and positioned in either horizontal or vertical orientations to suit the inspection task.
This versatility makes it especially effective for scanning complex structures like bridge piers, seawalls, and offshore platforms without needing to rely on traditional towed sonar methods.
Complementing this flexibility is an adjustable tilt block with up to ±30° mechanical tilt and an internal compass module that provides real-time heading, pitch, and roll data.
Together, these features remove the guesswork from sonar positioning, enabling operators to precisely align the beam and capture accurate, high-quality data on the first pass.
Advanced Sonar Software Integration with Data Mosaicing for Complete Underwater Visualization
The integration of MS 1000 software with advanced data mosaicing capabilities gives operators a powerful, streamlined workflow for capturing and analyzing underwater data.
With features like track plotting, target measurement, geo-referencing, and annotation tools, users can plan precise survey paths and accurately track objects or structures in real time.
After data collection, multiple scans can be stitched together through mosaicing to create a complete, high-resolution view of large assets such as docks, seawalls, or subsea infrastructure.
This eliminates the limitations of viewing small sections in isolation and provides a clear, comprehensive perspective that supports better decision-making and reporting.
Sonar Performance Specifications by Frequency
This table outlines how the Kongsberg 1171-Series performs across different operating frequencies, giving you a clear view of how beam width and range adjust based on your selected settings.
It helps you quickly understand the tradeoffs between coverage, resolution, and detection range so you can choose the optimal configuration for your specific inspection or survey application.

Kongsberg 1171 High Resolution Sonar Head Series with Flexible Frequency Control and Multi-Sonar Scanning Capability
The wide-frequency, dual transducer configuration combined with simultaneous multiple scanning and ping synchronization gives operators unmatched flexibility and efficiency in the field.
With tunable frequencies ranging from 600 kHz to 1.5 MHz and support for both fan and cone beam shapes, the system adapts to different inspection needs without requiring additional equipment.
At the same time, the ability to run multiple sonar heads and sensors simultaneously with synchronized pings allows for faster data collection and a unified, time-aligned dataset.
This means you can capture more accurate information in less time while maintaining clarity across varying ranges and conditions. If you’re looking to streamline complex surveys and eliminate the need for multiple systems, this capability delivers a smarter, more efficient approach to underwater imaging.
