pronounced.
Zoom 2X
The zoom 2X button lets you split the sonar screen in half. The left half shows the
standard view, while the right half shows a zoomed-in view of a portion of the water
column.

The right half is zoomed in by a factor of two, which means that half the amount of water
column is shown, but the sonar images appear twice the size.
When you first press the Zoom 2X button, the zoom window automatically focuses on
the bottom half of the water column. A green “bounding box” in the left side of the
window indicates the area being zoomed. You can reposition the box by using the green
arrows as handles: just touch either one of the arrows and drag the box up or down. As
you move the green box, the right side of the window magnifies the selected area. This
lets you zoom in on different parts of the water column.
The 2X Zoom screen on the right shows only the area from 16 to approximately 55 feet.
Gain
Gain controls the sensitivity of the sonar receiver. Higher sensitivity lets you see more
sonar detail, while lower sensitivity is helpful in reducing screen clutter for greater display
clarity.
The higher the gain, the more sensitive the receiver. Lower the gain to clear any extra
noise caused by murky water. If you are in a very clean freshwater lake, you may want
to increase the gain to see more detail in the water column.
The factory default setting for gain is auto. The auto setting lets Maestro Navigator
automatically adjust the gain based on speed and depth. This works well most of the
time, but if you feel that you need to set the gain manually, touch the Gain button and
