The next‑generation EdgeTech 4205 is a highly versatile side‑scan sonar system available for rental through GoSubsea, designed to support almost any survey application from shallow coastal work to deep‑water operations. Utilizing EdgeTech’s Full Spectrum® CHIRP technology, the 4205 delivers crisp, high‑resolution imagery at ranges up to 50% greater than non‑CHIRP systems, enabling operators to cover larger areas more efficiently and reduce overall survey costs.
In addition to the high‑quality imagery EdgeTech is known for, the 4205 introduces several advanced features that enhance flexibility and performance in offshore environments. The system can be supplied in either a tri‑frequency configuration or a motion‑tolerant, multi‑pulse configuration.
• The tri‑frequency version allows surveyors to operate any two frequencies simultaneously, offering excellent adaptability across varying seabed conditions.
• The motion‑tolerant, multi‑pulse version supports higher survey speeds and operation in rougher weather while still maintaining high‑quality imagery. It can also be run in a single‑pulse high‑resolution mode when a more detailed view of the seafloor is required.
With its combination of range, resolution, and operational flexibility, the EdgeTech 4205 is well suited for a wide range of subsea tasks, including cable and pipeline surveys, geological, geophysical, and archaeological investigations, mine countermeasures (MCM), geohazard and channel clearance work, and search and recovery operations where reliable, high‑clarity imaging is essential.
