Edgetech 4205

Description

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 makes

the system even more flexible and powerful in offshore operations. The 4205 is available

in either a tri-frequency side scan 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. The

4205 motion tolerant configuration with multi-pulse provides surveyors the ability to operate

either at faster survey speeds or in more adverse weather conditions while still obtaining

high quality underwater imagery. Additionally, this configuration can be operated in a single

pulse high-resolution mode for those operations that require an even more finite view of the

seafloor.

In both the tri-frequency and motion tolerant/ multi-pulse 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. All

EdgeTech 4205 systems are comprised of a topside system and a reliable stainless steel

towfish. Topside processors come in a choice of configurations from portable to rack mounted

units. In addition, an easy-to-use GUI software is supplied with every unit.
