EDGETECH 4200-FS (100/400kHz)

The 4200 uses EdgeTech's Full-Spectrum Chirp technology to deliver wide band, high energy transmit
pulses, coupled with high- resolution and superb signal to noise ratio echo data. The system employs
wide band, low noise front end electronics which reduce system induced phase errors and drift to
negligible levels. The sonar data is also optionally available as a complex, fully coherent data set
suitable for advanced user applied post processing.
