The 76 SERIES are high performance, dual frequency transducers combining both HIGH and LOW frequency sections in a single unit.

The ability to specify any combination of frequencies in the same basic unit, provides the echo sounder manufacturer and hydrographer with a versatile sounding system combining high resolution with good range performance.

The well defined beam pattern combined with the dual frequency option makes the 76 SERIES an excellent choice when measuring sediment layers.

The high impact strength nylon bodyprovides a mechanically robust and corrosion free transducer.
