Model 320 Series

Model 320 Series

The 320 SERIES continues the company’s successful policy of providing a range of frequencies in the same transducer shape. Compatible with a wide range of echo- sounders, the piston elements are configured to achieve optimum echo-sounder performance. 

The fully moulded polyurethane housing provides a mechanically robust, corrosion free transducer for hull or over-side mounting, offering maximum flexibility at minimum cost. 

The 320 SERIES is available with or without acoustic calibration, traceable to National Standards. Transducer impedance can be adjusted to suit customers specification.
