NOTE:
Using the Zoom command while in auto Range mode will always
enlarge the echoes near the bottom, because auto Range always
keeps the bottom displayed in the lower portion of the screen.
When you Zoom in manual Range mode, echoes are enlarged near
the middle of the displayed range. For example, with a manual
depth Range of 100 feet, your screen shows the water column from
zero at the top of the screen to 50 feet in the middle to 100 feet at
the bottom of the screen. Select 2X Zoom and the screen will show
the water column from zero to 50 feet, with 25 feet shown in the
middle of the screen. Select 4X Zoom and the screen shows the wa-
ter column from 13 feet to about 39 feet, with 25 feet still in the
middle of the screen.
Important Tip:
Your unit has the handy ability to quickly zoom in on any portion of
the water column with just the touch of an arrow key. The Zoom
Pan feature lets you rapidly move the zoomed area up and down to
different depths. By "pointing" your zoom at different portions of
the chart as it scrolls, you can get a good, close-up look at structure
or cover below you.
To use Zoom Pan, switch to a manual depth Range setting (see page
33) and turn on 2X or 4X Zoom. Then, simply press the
UP ARROW
or
DOWN ARROW
to pan up and down the water column.
In 34 feet of water, with the Range set manually at 60 feet, the unit
shows the entire water column in Fig. 1. To get a closer look, turn
around and follow your wake to troll over the structure again. With
the unit in 4X zoom, press the down arrow key to look at the six fish
along the ledge, then press the up arrow to pan up the water column to
see four game fish threatening a school of forage fish.
