The MarCum MX-7GPS 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, under the SONAR sub menu, select 
the “Auto” box menu under the Zoom Depth. 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, GPS Map 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 highlight 
“Zoom Depth” under the Sonar Settings sub menu, this is where you 
set the uppermost limit of the Zoom Display by pressing the 
PLUS/MINUS buttons. When you have the desired depth 
highlighted, pressing “X” to close the menu, or selecting other 
options 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 have Sonar setting highlighted; 
then highlight “Zoom Window”. You can now select which size zoom 
window you want using the PLUS/MINUS buttons to increase or 
decrease the size of the window. Going through this process several 
times before you go fishing is a great idea, as that will allow you to 
easily and quickly adjust right away once on the water. 
 
For example, if you were fishing in 30 feet of water, and wanted to 
zoom in on the bottom 10 feet, press the Menu button and within the 
Sonar Settings submenu highlight Zoom Depth. Use the 
PLUS/MINUS to set the zoom depth for 20 feet (10 feet off bottom). 
Now using the arrow pad highlight the Zoom Window.
