Echoes Series

A complete range of sub-bottom profilers covering the full spectrum
Plus d'information

Vue d'ensemble

More than just a sub-bottom profiler, the Echoes Series provides a complete solution for acquiring, processing and interpreting high-quality geological data thanks to its integration with the provided Delph Seismic software.

Echoes sub-bottom profilers use an acoustic array of transducers that are using the piezoelectric ceramics properties of ceramics in which a high-voltage current is sent. The properties of this signal are reproduced by the emitted acoustic soundwave (Chirp, CW, Ricker, etc.). Thanks to the reciprocal piezoelectric principle, this acoustic array can be used to sense the reflected soundwaves.

  • Very low distortion power amplifiers (Low frequency: flat spectrum)
  • In-house manufacturing and design of our transducers (Tonpilz technology), electronics and software
  • Clear interfaces, contrasted images, texture of layers


  • Compact antenna: transducer remains small and lightweight (easily operated by a single man for Echoes 10000)
  • Possible to use other acoustic sensors such as a multi-beam echosounder with no acoustic interference and without an external synchronization needed
