sub basement profiling on rivers

[goldenshamrock]

Good Day, have just joined and read few a few threads prior. I am interested to know of anyone's experiences or knowledge of using sonar, as an example for sub basement profiling of rivers. Basically to determine and pinpoint areas below the perceived river bottom that may have cavities, pockets, less dense material, faults and cracks. Primary interest is to more accurately identify these spots for potential catchment points for diamonds and possibly gold. River depths 5 to 20 feet. Sub basement depths wishing to explore up to another 20 feet below as initial assessment. All comments welcome.

You might want to post this below in the "Side scan sonar" forum. There are a few experts that might be able to help you. Have you tried a digital fish finder?
