For example, if you were fishing in 30 feet of water, and wanted to zoom in on
the bottom 10 feet, press ZOOM, and then set the zoom depth for 20 feet (10
feet off bottom). Now press MENU, highlight “Zoom Window”, and select 10
feet. The 20 to 30 foot portion of the water column is now displayed on the
Zoom display, and the entire water column is viewable on the flasher window.
The LX-7 also features “Chart Zoom” which enables you to use a scrolling
graph in Zoom mode. Activate the Chart Zoom in the Display Options of the
menu. You set the zoom just as you would when using the other sonar options.
When you press the ZOOM button to make a change, the Vertical Zoom
window will automatically open. After adjustments have been made, you may
turn the Vertical Zoom window off again in the Display Options of the menu.
Cone anGle Info
A feature unique to the LX-7 is the “Sonar Footprint” that displays the actual
area being covered by your transducer while you are fishing. This data is
displayed below the cone angle icon, and represents the diameter of the base
of the transducer cone. This will keep you constantly updated how much area
is being covered by your LX-7, and will help you decide which transducer angle
best suits the conditions. When the LX-7 is first turned on, it will be transmitting
utilizing the 20-degree setting. To switch from 20 degree to 8 degree, simply
press the CONE ANGLE button once, and the CONE ANGLE icon will change
from 20 degree to 8 degree, and the Sonar Footprint will change with it.
Conditions where the narrow beam will benefit you are:
1—Fishing in deep water (over 40’) for walleyes, perch, or lake trout
2—Fishing along very steep drop-offs for bottom-hugging walleyes
3—Fishing in big schools of fish, like suspended crappies or tullibees
4—Fishing in and around heavy weeds for panfish, like bluegills and crappies
5—Fishing in a crowd, the narrow beam will reduce interference from your
neighbor
InTerPreTInG sIGnals
DIGITAL DEPTH— The digital depth display on the LX-7 provides a quick and
easy way to determine depth. Digital Depth is always displayed in the center of
the circular display, and on the bottom of the vertical displays. It will also show
in the upper left corner of the graph in some configurations. This display can
be used as a quick reference when checking depths through the ice.
READING BOTTOM— When interpreting your bottom signal, always read the
leading edge (shallowest side) of the signal return. If you have a strong signal
return (wide band) and it starts at 13 feet and ends at 16 feet, the correct depth
is 13 feet or the shallowest leading edge of the return signal. Anything beyond
the shallowest leading edge indicates the strength of the return signal.
Your LX-7 can also be used to determine bottom composition. The thicker
and bolder your bottom shows, the harder the bottom is. In some cases, hard
