The GeoAcoustics’ Over The Side (OTS) Mount has been in use for over 20 years and is a tried and tested design for mounting sonar equipment on various vessel types. It provides a reliable and stable mounting platform for a vast array of sonar equipment such as side scan, bathymetric or sub-bottom profiler systems. 

Although principally designed for operation with GeoAcoustics Ltd equipment, the OTS mount can be modified for use with almost any third-party sensor using a simple custom adapter. The simple, yet rugged design offers clear advantages over other systems employing work drives to raise and lower the pole. Further, a range of GNSS position / heading sensors can be fitted to the top of the OSM pole set.
