you to have a magnified 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, and can be moved so
as to focus on the bottom (for detecting bottom-hugging fish), or at any level
above bottom for suspended fish.
The Marcum Digital Sonar also offers Auto Bottom Lock 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 Bottom Lock 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 Marcum Digital Sonar can be accessed in several
ways depending on which sonar windows you have displayed on your
dashboard. Having your Digital Sonar 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.
Begin from the factory default screen open (Flasher in center, Vertical Display
on left, Vertical Zoom on right). 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.
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
