Model 395 Series

Model 395 Series

The 395 SERIES transducer is intended for vertical depth sounding applications. The frequencies selected are compatible with a wide range of echo-sounder types. The concentric element arrangement generates a conical beam pattern with low side lobes. 

The polyurethane housing provides a mechanically robust, corrosion free transducer, suitable for tank, thru-hull or over-side mounting. 

The 395 SERIES is available with or without acoustic calibration which is traceable to National Standards. Transducer impedance can be adjusted to suit customers specification.
