Edgetech 4205 Tri Frequency Towfish

Availability: Rental

The next-generation 4205 is a versatile side scan sonar system that can be configured for almost any survey application from shallow to deepwater operations. The 4205 utilizes 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 a number of new features which make the system even more flexible and powerful in offshore operations.

The 4205 is available in either a tri-frequency sidescan sonar configuration or motion tolerant and multi-pulse configuration. 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 230/540kHz combination. Then, on-demand the system can be changed to a 540/850kHz system for an even higher resolution survey.

In the tri-frequency configurations, towfish and target positioning has been improved with the integration of a more accurate heading sensor that can be coupled with an optional USBL beacon. Additionally, all systems now come with Increased towfish power to support a wider range of additional 3rd party sensors.

Standard 701DL or Starmux transceivers can be used as the topside interface and power supply for the Tri-frequency towfish.
