Sub-bottom Profiling Module
The Gavia Sub-Bottom Profilng Module Is Derived From Field Proven Chirp Iii Technology From Teledyne Benthos, Pioneers in Chirp Technology
The Chirp Sonar uses digitally produced 14kHz-21kHz acoustic transmission and matched-filter processing to achieve both high resolution and good penetration in soft sediments.
