The 1171 Series of sonar heads have been developed to meet the requirements for both shallow and deep ocean applications. As well as the choice of operating frequencies, the new sonar heads feature faster scanning rates, improved range resolution and even clearer, sharper images, all in a more compact lighter housing.

1171 Series - Obstacle avoidance imaging sonar heads

The dual transducer design allows optimised operational configuration for both long range obstacle avoidance and shorter range imaging detail. The transducer is protected within an oil-filled, pressure compensating dome. The telemetry is RS485 and RS232 compatible and is automatically sensed and configured at start up to match the telemetry link used. The sonar head operation is configured and controlled using the MS1000 Software Processor. Other features include:

  • Dual transducers for multi purpose obstacle avoidance and inspection use
  • Multiple frequency capability (330 to 400 kHz and 450 to 700 kHz)
  • Improved range and scanning rate
  • Improved sampling resolution & beam foot print resulting in clearer, sharper images
  • Improved Range Resolution
  • Lighter 4000m depth rated design
  • Optional Ethernet telemetry interface

1171 Series - Multi frequency profiling heads

The Multi-Frequency design allows optimising of the profiling configuration for different applications. Like the sonar head, the transducer is protected within an oil-filled, pressure compensating dome and the telemetry is automatically sensed and configured at start up to match the telemetry link used. The sonar head operation is also configured and controlled using the MS1000 Software Processor.

  • Multiple frequency capability (675kHz to 1.35 mHz)
  • Improved range and scanning rate
  • Clearer, sharper images and a >0.5 cm range resolution
  • Sample resolution of > 0.5mm
  • Lighter 4000m depth rated design
  • Optional Ethernet telemetry interface
