Humminbird Side Imaging Sonar is a great know-how that can help you find more fish faster. Normal "2D" fishfinders look straight down, mostly giving you a view underneath the boat. Side Imaging fishfinders can look to the side of the boat up to 240 feet on each side. That's a total of up to 480 feet around the boat! The sonar's high frequency beam can also map underwater structures such as reefs and wrecks.

So how does this help you find more fish? simple! It lets you see a immense volume of water and also gives an excellent, detailed view of fish attracting structures so that you can see fish that other anglers cannot.

Let's say you fish in freshwater lakes, rivers, ponds, etc. With lots of waterways being over fished nowadays, most anglers will focus on fishing from docks, near the shore or near grass. With Humminbird Side Imaging on your side you'll be able to go out in to the open water and find submerged structures that others can't see easily with their standard "2D" sonar. Your fish finder will help you find timber, stumps, rocks and anything else that attracts fish. You'll even be able to observe transitions from soft (muck) to hard (gravel, sand) bottoms and you know fish loves these transitions. You could identify these transitions with a standard fish finder, but it would need tirelessly circling the water until you are directly above the transition and great skill at reading your fish finder display. With the side imaging sonar you'll not only find these transitions easily, but be able to see them extending for several hundred feet.

in case you fish more in saltwater your side imaging fish finder will give you detailed views of reefs, wrecks and dropoffs, all places fish like to hide. The narrow high frequency beam will let you easily distinguish between the fish, the reef (or other structure) and the bottom. It will also show you baitballs and of work, Fish!

The Humminbird Side Imaging fishfinders do include standard downlooking "2D" sonar if that is more to your speed. basically switch to the "2D" mode and use your fish finder the way you're used to.
