Fig. 3-10 Zoom Feature On

Zoom area
When you turn on the zoom feature, it can only enlarge a part of the
Downlook display. You must decide which part you want to enlarge.
As we said, the right side of the display shows the normal Downlook
display. The vertical line at the right edge of this display shows the
area or "window" of the water being enlarged. On the right edge of the
zoomed section of the display, the number at the top of the display
shows the depth at the top of the zoomed area. The number at the
bottom shows the depth at the bottom of the zoomed area.
When the Fishfinder is set for Auto Zoom, it will choose the zoom area
automatically. The unit always chooses an area of the water which
includes the bottom. The unit then moves this area up or down to keep
the bottom in the picture. The Auto Zoom feature is helpful for bottom
fishing.
