You can adjust the zoom of the Full Screen page, the Split Zoom page, and
the Split Frequency page manually, or you can allow the device to adjust the
zoom automatically.
Adjust the zoom manually by selecting the span (amount of sonar data that
will be displayed in the zoomed window) and selecting a xed starting
depth. For example, if you select a span of 15 meters and a starting depth
of 5 meters, the device will display an area from 5 meters deep to 20 meters
deep.
When you adjust the zoom automatically, the span is the area that will be
displayed on the screen from the contour of the bottom of the water. For
example, if you select a span of 10 meters, the device will display an area
from the bottom of the water to 10 meters above the bottom.
