Note: Do not use Wide beam for determining bottom hardness or features. Wide beam is not suited for accurate
bottom feature detection.
Sensitivity: 90-100%, depending on how clear the water is. Reduce this setting gradually until the screen is
free from clutter and small dots. Keep this setting at maximum if the water is crystal clear.

There are 3 factors that need to be considered when evaluating the hardness of the bottom:
1. Color. The more vivid and bright colors mean harder bottoms. In Day Color Palette, hard bottom will always be
shown in bright yellow color. Soft bottom will consist of darker colors, and you will see more blue and red.
2. The thickness of the line representing the bottom is also an indicator of the bottom hardness, the thicker
the line, the harder the bottom. Keep track of the color as well - if a bottom line that consists of yellow color
gradually turns red, and becomes thicker - it doesn't mean that the bottom is harder in the spot that you are
scanning. It simply means that there is a thicker layer of softer soil. Color should be the first factor to consider
(yellow = hard, red = medium, blue = soft).
