  • Side Scan Sonar 4205

The EdgeTech 4205 is a versatile side scan sonar system that can be configured for almost any survey application from shallow to deep water operations. The 4205 utilises EdgeTech’s Full Spectrum® CHIRP technology to provide crisp, high-resolution imagery at ranges up to 50% greater than non-CHIRP systems; thus, allowing customers to cover larger areas and save money spent on costly surveys. In addition to the high-resolution imagery that EdgeTech is known for, the 4205 comes with several new features which makes the system even more flexible and powerful in offshore operations.

The 4205 is equipped with tri-frequency transducer array. The tri-frequency version allows surveyors the option to operate any two frequencies simultaneously from the tri-frequency system. Long range operations for example can be achieved with a selection of 230/540 kHz combination. Then, on-demand the system can be changed to a 540/850 kHz system for an even higher resolution survey. In the tri-frequency, towfish and target positioning has been improved with the integration of a more accurate heading sensor. The system comes with increased towfish power to support a wider range of additional third-party sensors.

The EdgeTech 4205 system is comprised of a topside system and a reliable stainless steel towfish. Topside processors are rack mountable and come with easy-to-use GUI software that can be installed on the optional industrial workstation, laptop or customer-provided PC.
