Welcome to Clydeside Surveys Limited.
The 4125 Dual Frequency Side Scan Sonar system is the ideal tool for seabed feature mapping, offering flexibility and high quality results in a simple and reliable package.
The system offers high resolution, switch selectable, dual frequency operation (400/900 kHz), which when combined with multiplexed data transmission enables a low drag co-axial tow cable to be used. This also facilitates simple installation onto remotely operated vehicles (ROV’s) and combined systems towfish.
The standard system employs a lightweight towfish which is easily deployed by one person and can operate to a depth of 1000 metres. There are separate controls for each channel, which makes the system very easy to operate. Optional extras include a deeper rated towfish, a towfish instrumentation package and a stainless steel towbody.
The basic system includes the following:
The multiplexed data transmission technique employed allows the system to be used with a wide selection of towcables, including twisted pair and co-axial cables. Data from the dual frequency side scan sonar can be input to many sonar processing systems, including a GeoPro Sonar Processor or it can be displayed on a wide variety of industry standard graphic recorders.
