The EdgeTech 4200 Series is a highly versatile side‑scan sonar system designed for survey operations ranging from shallow coastal work to deep‑water missions. Built on EdgeTech’s Full Spectrum® CHIRP technology, the 4200 delivers crisp, high‑resolution imagery at ranges up to 50% greater than conventional non‑CHIRP systems. This extended coverage allows operators to survey larger areas more efficiently, reducing vessel time and overall project costs.
Its imaging performance and flexible configuration make the 4200 well suited for a wide range of subsea tasks, including cable and pipeline surveys, geological and geophysical mapping, mine countermeasures (MCM) and channel clearance, as well as geohazard and archaeological investigations. The system is also a strong choice for search and recovery operations where reliable, high‑clarity imagery is essential.
