Seismic, Sub-Bottom, Side Scan, and Combined Sonar Systems

Bubble Gun Low-Frequency Acoustic Seismic Systems

CHIRPceiver Sub-Bottom Profiling Systems

Side Scan Sonar and Combined Systems

Low-frequency acoustic signals provide superior sub-bottom penetration through coarse sand, gravel tills, and other difficult sediments

Two Available Transducers:
Standard 70 Hz to 2 KHz
Low Frequency LF 20 Hz to 2 KHz
 

Small component size, portability, and low power requirements make this a valuable tool for any survey platform

Multiple Sources can be synchronized to a common trigger without need for external timing control

Highly repeatable shot-to-shot phase and amplitude wavelet correlation and clean source frequency bandwidth signatures facilitate post processing & data analysis
