Innomar Sidescan Extension

Innomar sidescan-extension (100kHz)

With this extension Innomar's "compact" shallow-water sub-bottom profiler can be turned into a digital sidescan. For this the SBP transducer is replaced by a sidescan sonar-head operating at 100 kHz.

This sidescan extension can be used in applications that require not only sub-bottom data but also to determine seabed morphology and/or objects on the seabed. Applications include surveys in the dredging industry (looking for outcrops), archaeological surveys, pipeline tracking and presurveys of construction sites.

Please note that the sidescan head is interchanged with the SBP transducer and therefore sidescan and sub-bottom data cannot be acquired simultaneously.
