Side Imaging


Humminbird’s Side Imaging is an ultra-thin beam which will scan the left and right side of your boat’s location. It offers a 180 degree side-to-side perspective of the below surface. The returned images then combined into the display with an excellent view of the lake bottom. With the big display, you will be able to read them and magnify the details and even mark the location on GPS.

It provides a photo-like image of the bottom which is sent by the sonar. However, it’s not a real photo. If you are a newbie, you may find the image distorted, which is not. Right after seeing some principle you will be able to understand what’s beneath your boat.

As the boat moves forward, the sonar will understand the changes. Thus, you will get a compiled data of the lake bottom. No matter whether it’s dark or sunny, the clarity of water has no impact on it. You will be able to get a live camera like images. The range lines, contour mode and color palette will be very useful.
