SES-2000 standard plus Sub-Bottom Profiler
and Sidescan Sonar
The SES-2000 standard plus model is designed for getting sub-bottom profiler data in shallow-water applications down to 500m.
A superior feature of this SES-2000 model is the possibility to get dual-frequency sidescan data at the same time as the sub-bottom and echosounder data.
SES-2000 standard plus data example (frequency: SBP 8kHz, Sidescan 410kHz; water depth 4 meters).
