This capture shows a school of herring. Even though the MS70 detects and records data from all 500 beams, only two
sectors can be shown in a traditional 2D view. One is a horizontal slice, while the other is a vertical slice through the
matrix. Two views hold zoomed data, while the view on the left side shows an echogram from the single beam shared by
the two sectors. (Data kindly provided by IMR, Norway.)
