When you Zoom in manual Range mode, echoes are enlarged near
the middle of the displayed range. For example, with a manual
depth Range of 100 feet, your screen shows the water column from
zero at the top of the screen to 50 feet in the middle to 100 feet at
the bottom of the screen. Select 2X Zoom and the screen will show
the water column from zero to 50 feet, with 25 feet shown in the
middle of the screen. Select 4X Zoom and the screen shows the wa-
ter column from 13 feet to about 39 feet, with 25 feet still in the
middle of the screen.
SENSITIVITY
Sensitivity controls the unit's ability to pick up echoes. If you want to
see more detail, try increasing the sensitivity, a little at a time. There
are situations when too much clutter appears on the screen. Decreasing
the sensitivity can reduce the clutter and show the strongest fish ech-
oes, if fish are present. As you change the sensitivity setting, you can
see the difference on the chart as it scrolls.
These figures show results of different sensitivity levels on the same
location. Fig. 1: Sensitivity at 87 percent, determined by Auto Sensitiv-
ity. Typical of full auto mode. Fig. 2: Sensitivity set at 50 percent. Fig.
3: Sensitivity set at 20 percent. Fig. 4: Sensitivity set at 100 percent.
