For example, if you are fishing in 60 feet of water but are only interested in the first 30 feet
(surface to a depth of 30 feet) you should set the Lower Depth Range limit to 30. The display
will show the 0 to 30 foot range, which allows you to see a more detailed view than you would
see if the display went all the way to the bottom.

For example, if you are only interested in the area between 20 and 50 feet deep, you should
set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Down Imaging™ View
will then show the 30 foot area between 20 and 50, and will not show the surface or the
bottom (assuming the bottom is deeper than 50 feet), and will show greater detail for that area
between 20 and 50 feet.
