Since 1957, recreational sonar technology has been available to avid boaters and fishermen. A standard fishfinder is a sounder or recreational sonar that provides anglers with the ability to locate and target open-water fish. This view of underwater specifics allow the crews to understand depth contours, bottom composition, and structure location.

Nowadays, a modern sounder or fishfinder displays measurements of reflected sound on a graphical chart allowing crews to identify:

  • schools of fish
  • underwater debris
  • bottom of body of water
