EdgeTech, the leader in high resolution sonar imaging systems and underwater technology, recently added a new frequency pair to the popular 4200 Side Scan Sonar. The EdgeTech 4200, a multi-purpose survey system that can be configured for shallow or deep water operations is now available with a 100/600 kHz frequency pairing. This unique dual simultaneous frequency combination allows surveyors the ability to achieve an along track resolution of 2.5 meters at 200 meters range (with MP Technology) and 0.45m at 100 meter range. Across track resolution is 8cm and 1.5cm respectively.
With its unique Multi-Pulse (MP) technology, which places two sound pulses in the water rather than one pulse like conventional side scan sonar systems, the EdgeTech 4200 can 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.
