Model 65 Series

Model 65 Series
  • MULTIPLE FREQUENCY OPTIONS
  • SINGLE NARROW BEAM
  • LOW SIDE LOBE
  • LONG RANGE ECHO SOUNDER
  • TOWED BODY CAPABILITY
  • FULLY MOULDED

The 65 SERIES transducer is a high power, long range directional array operating at several frequencies. Originally designed for over-side installation, the 65 SERIES can also be hull mounted. The nodal mounted tonpilz elements are extremely robust, capable of withstanding high slamming forces, highly efficient and provide an excellent front to back ratio. An external transformer can be supplied to accommodate any impedance matching. The transducer housing is an over-moulded, robust and corrosion free transducer body. 

The 65 SERIES is available with or without acoustic calibration, traceable to National Standards.
