The Echoscope is a new state-of-
the-art real-time 3D sonar system
developed and manufactured by
Coda Octopus since the early
2000s.
It is widely deployed for a wide
range of subsea applications
across commercial, defence, and
research sectors such as marine
construction, offshore energy,
pipeline and cable surveys, bridge
and port inspections, dredging,
and salvage operations—enabling
precise placement, verification,
and monitoring even in zero-
visibility conditions.
In the defence sector, it supports
mine countermeasures, diver
tracking, hull inspections, and Port
and Harbour security, while its
compact variants integrate easily
with ROVs, AUVs, and diver
platforms, making it a versatile
tool for complex underwater tasks.
Unlike traditional sonar systems
such as Side Scan, Multibeam
Echosounders (MBES), or
Multibeam Imaging Sonars (MBIS),
the Echoscope is the only
technology in this group capable
of delivering true real-time 3D
volumetric imaging. It generates a
complete 3D dataset in a single
sonar ping, without relying on
accurate positioning and
mosaicking or combining
multiple frames over time.
To illustrate how these
technologies differ, consider the
