Sensitivity Controls the level of detail shown on the display. Too much detail will clutter the screen. If Sensitivity is set too low, desired echoes may not be displayed. NOTE: You can make changes (+/-40%) to sensitivity with Auto Sensitivity turned on. You will have to turn it off to make significant adjustments. Colorline Separates strong sonar echoes from weak sonar echoes. That makes it easier for you to distinguish fish or structure from the bottom. A hard return will be shown as a wide, bright yellow area, whereas a soft return will be a narrow reddishblue area. Auto Sensitivity Keeps sensitivity at a level that works well under most conditions, reducing the need for adjustments. Auto Sensitivity is turned on by default. Range Selects the deepest range shown on the display. Range settings display the section of the water column from the water surface to the selected depth range. If you select too shallow a depth range, the unit will not be able to lock onto the bottom. Custom Range - Upper and Lower Limits Used to select the upper limit and lower limit of a section of the water column. That allows you to view a section of the water column that does not include the water surface. Upper and lower limits must be at least 5 ft (2m) apart. Sonar Operation | Elite-5 HDI 24
