Model 250 Series

Model 250 Series
  • FREQUENCY 115 KHZ
  • SIDESCAN TRANSDUCER
  • SEAFLOOR MAPPING
  • DEEP WATER CAPABILITY
  • HULL OR TOW-FISH

The 250 SERIES sidescan is a robust fully moulded construction, operating at 115 kHz the sidescan has a very wide bandwidth. 

With a narrow beam in the along-track axis and wide beam in the across-track axis, suitable for most sea-floor mapping and other high directivity applications. 

The company’s extensive transducer expertise has created products that are of high performance and substantially lower cost. A deep-water version, capable of operating down to 2000 metres is available to special order. 

The 250 SERIES is available with or without acoustic calibration which is traceable to National Standards.
