T37

T37
  • 200 KHZ DUAL BEAM
  • NAVIGATION, FISHING & SURVEYING
  • HIGH PERFORMANCE
  • SCIENTIFIC ECHO SOUNDER
  • HULL OR TOWED BODY
  • ROBUST NYLON HOUSING

The T37 is a precision echo sounder transducer designed for use in hydrographic or scientific applications where accurately defined beam patterns are needed. 

The pattern is configured to achieve conical beams both for wide and narrow beam widths and are switched using a beam selection switch box which can be supplied separately. 

The T37 is available with or without acoustic calibration which is traceable to National Standards.

Transducer impedance can be adjusted to suit customers specification.
