Model 270 Series

Model 270 Series

The 270 SERIES side-scan is a robust fully moulded construction, with 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 270 SERIES is available with or without acoustic calibration which is traceable to National Standards.
