The Knudsen 3260 echosounder has dual frequency capability: 12 kHz and 3.5 kHz
The EchoControl program, used to control the echosounder, will record files in Binary "echogram" files (.keb) and fully configurable ASCII data files (.kea). SEG-Y and XTF recording is also available on request for most frequencies. The EchoControl program can record all 4 data file types simultaneously allowing the user a wide range of options for interfacing with third party survey software. Event marks showing lat/lon & time can be recorded along the way to make a record of notable features.
