Eagle Electronics 240 User Manual

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.

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.
