ZooM
One of the best features to have in an ice fishing Sonar is a “Zoom”, and there is
none better than that of the LX-7. A Zoom feature enables you to have a magni-
fied view of a selected portion of the water column. Note that when the ZOOM
window is open, you can still view the entire water column on one of the other
windows. Imagine that you are fishing for walleyes in 30 feet of water, and you
are zoomed in on the bottom 5 feet. If a school of crappies comes through at 20
feet, you will be able to easily see them on one of the other windows, and quickly
raise your bait to their level. The position of the ZOOM window is adjustable in
one-foot increments. The ZOOM can focus on bottom (for detecting bottom-
hugging fish), or at any level above bottom.
The LX-7 also offers Auto Bottom Track Zoom that automatically zooms and
locks onto the bottom, even when you change locations. This is especially useful
for if you are hole-hopping for bottom hugging fish like walleyes and perch. To
access the Auto Zoom, press ZOOM, and then press the UP button until “A”
(Auto) appears. It will appear after you pass “0” on the Zoom Window.
The ZOOM feature on the LX-7 can be accessed in several ways depending on
which sonar windows you have displayed on your dashboard. Having your LX-7
set at the factory default setting for a screen configuration will make it easiest
to learn how to use the Zoom. It is highly recommended that you learn how the
Zoom works while in simulator mode. Operating the Zoom is quite simple, and
only requires the pressing of a few buttons to select the size and position of your
Zoom Window.
So, start by having the factory default screen (Flasher in center, Vertical Display
on left, Vertical Zoom on right) open. The area that is featured on the Zoom
Display is indicated by the “Zoom Indicator Bar”, a light blue bar on the right
side of the Vertical Display. When you press the ZOOM button, a “Zoom Depth”
window will appear at the bottom of the screen. This is where you set the
uppermost limit of the Zoom Display by pressing the UP/DOWN buttons. When
you have the desired depth highlighted, pressing ZOOM again will establish that
depth as the top of your Zoom display. You will notice that the Zoom Indicator
Bar will move up or down as you make these adjustments. To set the size of what
is shown in the Zoom Display, press MENU, and then highlight “Zoom Window”.
You can now select which size zoom window you want.
Going through this process several times before you go fishing is a great idea,
as that will allow you to easily and quickly make adjustments right away once on
the water.
If you have only the Flasher Display, the Vertical Display, or the Scrolling Graph
Display open, and go into zoom mode, pressing the “ZOOM” will cause the
vertical zoom window to appear, and a “Zoom Depth” window will open at the
bottom of the screen. You will still set the uppermost limit of your zoom window
here, but you won’t have the advantage of having the Zoom Indicator Bar to
show you exactly what area is being highlighted. With a little bit of experience,
you’ll find this to be quite easy to do. Just set the zoom depth for 5, 10, 20,
or 40 feet above the bottom, and then set the Zoom Window to the size that is
appropriate.
