T197

T197
  • DUAL FREQUENCY NAVIGATION & SURVEYING
  • LOW SIDE LOBES
  • LONG RANGE ECHO SOUNDER
  • TOWED BODY CAPABILITY
  • FULLY OVER-MOULDED
  • (OPTIONAL) DEEP-WATER 1800M VARIANT AVAILABLE

The T197 is a high performance, dual-frequency transducers offering a versatile sounding system with high resolution and excellent range performance. The design features both high and low frequencies combined within a single over-moulded housing. Allowing a hydrographer the flexibility to select a system to meet the desired survey requirements of resolution, range, silt penetration and beam pattern. The over-moulded polyurethane housing provides a mechanically robust, corrosion-free transducer for hull or over-side mounting.

Transducer impedance can be adjusted to suit the customer's specification.

The T196 is available with or without acoustic calibration which is traceable to National Standards.
