Aquazond Side Scan Sonar GBO-200M

The Side Scan Sonar GBO-200M, while the vessel is in motion, allows for the measurement and recording of the seabed profile beneath the vessel and provides hydroacoustic images of the seabed surface to the left and right sides of the vessel.
The GBO-200M is designed for installation on various vessels using an overboard deployment system and is used in hydrographic, surveying, scientific research, and emergency rescue operations.
The GBO-200M consists of a depth-sounding echo sounder channel and a side-scan sonar channel.
The GBO-200M includes:
- Hydroacoustic transceiver antenna SA-015 — 2 units
- Satellite navigation system signal receiver antenna — 1 unit
- Electronics unit GBO-200-Depth-M
- Charger for built-in batteries
