EdgeTech has recently delivered eight 4200 Side Scan Sonar Systems to the U.S. Naval Oceanographic Office (NAVO). Four of the systems are single frequency 600 kHz Dynamically Focused and the remaining four are dual simultaneous frequency 300/900 kHz systems.
The EdgeTech 4200 was selected by NAVO due to its very high resolution imagery and long range capability. The systems will be used for shallow water surveys worldwide.
