It’s all in the details. Gain a 180 degree side-to-side perspective on the
world below the surface with remarkable Humminbird® Side Imaging®. In an
instant, the ultra-thin beam scans the area up to 240 feet to the left and right
of your boat location—for total coverage of up to 480 feet. The return image for
each slice is then added to the images taken immediately before and after to
build an incredible view of the lake bottom. You can then magnify the detail of
the image with the zoom feature or mark the GPS location of promising cover or
structure directly on the screen.
Side Imaging's high-frequency beams reveal structure, cover, and contour changes
with crystal clarity. The images are so real you might think it’s a camera, but
it’s not, so it doesn’t matter how murky the water is.
How to Read Side Imaging
Understanding a few simple concepts will help you grasp the detailed
images of Humminbird Side Imaging and make you a master of the lake or sea
bottom. Compare the screenshot and diagram to help visualize how Side
Imaging works. We’ve included several callouts to explain what you’re
seeing. Remember, Side Imaging is a history of what you’ve already passed
A- Boat Location
The position of your boat in relation to the on-screen image. The
on-screen image is a history of what you have passed over.
B- Water column
The dark blue area shows structure, cover and activity between the surface
and lake bottom.
C- Bottom Profile
Reveals depth and terrain directly beneath the path of your boat. D- Flat Terrain
Neutral shades of blue represent flatter terrain. E- Descending Terrain
Dark shades of blue represent descending terrain. F- Rising Terrain
Lighter shades of blue typically represent terrain rising from the bottom.
Sometimes, very hard bottoms appear as a whiter shade.
G- Fallen Log
The shortened horizontal shadows indicate cover very close to the bottom
of the lake. The angle of the shadow gives away the orientation of the
H- Standing Timber
Objects standing off the bottom directly below the boat will appear in the
water column. Structure to the left or right of the boat will appear as a
clearly defined bright shape with an adjacent, dark sonar "shadow." This
shadow is not caused by light; rather it's the lack of sonar return
because the object has already reflected the sonar energy. Generally, long
shadows indicate the object is tall, and small shadows indicate something
is short. It's important to note the shadow will often tell you more about
the object than the primary sonar reflection.
Visualizing Side Imaging
Reading the image produced by Humminbird Side Imaging is easy. Simply
visualize the screen folded in half down the middle (behind the boat).
Then, fold the image again at the lowest point of the water column. The
dark blue area provides a visual representation of the water column and
lake bottom directly below your boat.
Understanding the Beam
Humminbird Side Imaging Sonar uses a razor thin beam to take a “sonar
snapshot” of the area up to 240 ft. to the left and right of your
location. The return image for this slice is then added to the images
taken immediately before and after to build an incredibly detailed view of
the lake bottom.

Side Imaging reveals balls of bait that you can use when targeting
where fish are feeding.
