The 4200 Series is Edgetech’s most versatile side scan sonar system and can be configured for almost any survey application from shallow to deep water operations. The 4200 utilizes Edgetech’s Full Spectrum® CHIRP technology to provide crisp, high resolution imagery at ranges 20-30% greater than non-CHIRP systems; thus allowing customers to cover larger areas and save money spent on costly surveys.
One of the unique features of the 4200 is the optional Multi-Pulse (MP) technology which places two sound pulses in the water rather than one like conventional side scan sonar systems. This allows the 4200 to be towed at speeds of up to 10 knots while still maintaining 100% bottom coverage. In addition, the MP technology will provide twice the resolution when operating at normal tow speeds, thus allowing for better target detection and classification ability. The 4200 system comes available with the dual simultaneous frequency towfish of 100/400 kHz.
