Zoom Feature
The zoom feature allows you to view a smaller portion of the complete range in
greater detail.
The zoom feature operates in auto or manual mode. Auto zoom will follow the
bottom contour while manual zoom will display the selected depth. For more on
the zoom feature, see pages 26-27.
To use the zoom feature:
1. While viewing the Sounder Page, press
I
. The zoomed part of the display
(always the bottom part) shows you twice the detail of the original display at half
the depth.
2. Pressing
I
a second time shows you twice the detail of the original at half the
depth in one screen.
3. Pressing
I
a third time shows you four times the detail in the zoomed part of
the screen at a quarter of the original depth.
4. Pressing
I
a fourth time shows you four times the detail in the zoomed part of
the screen at a quarter of the original depth in one screen.
Note: When dual frequency is selected, there is no split zoom with a full range
over a zoomed window. Both the 50 kHz and the 200 kHz will zoom together,
regardless of which is on top or bottom.
To turn the zoom feature off, press
H
until the original scale picture appears and a triple beep
sounds.
