Adjusting the Zoom
You can adjust the zoom manually by specifying the span and a fixed starting
depth. For example, when the depth is 15 m and the starting depth is 5 m, the
device displays a magnified area from 5 to 20 m deep.
You also can allow the device to adjust the zoom automatically by specifying
a span. The device calculates the zoom area from the bottom of the water.
For example, if you select a span of 10 m, the device displays a magnified
area from the bottom of the water to 10 m above the bottom.
