Steele Associates has provided hydrographic surveying and mapping support on diverse and technically challenging projects. Our R2Sonic 2024 multibeam sonar is capable of 700 kHz ultra-high resolution data acquisition, the highest resolution available for any commercial shallow water multibeam echo sounder. The 2024 is ideal for offshore site survey such as pipeline inspections, cable laying operations or other bathymetric applications.
