Grayline

This series of figures shows how different Grayline settings can reveal more information. The "A" figures to the left show locations with Gray- line set at the factory level of 64 percent. At right, the "B" figures show the same locations with Grayline increased to 84 percent. In Figure 1B, no fish are near the left structure, but the right structure shows fish holding next to the structure. Notice in figures 2B and 3B how Grayline displays a hard, rocky bottom (the drop-offs) with a wider gray line. The muddier bottom below those drop-offs appears as a narrower gray line.
