Side scan sonar fish finder

The crab trap and speckled trout cannot escape detection. The darkness on your screen is right underneath your boat as your device scans out towards the sides.

In this video I explain how to identify fish on a side imaging fish finder.

Side scan sonar fish finder. Side imaging sonars also referred to as side-scan sonars are a set of sonar system that was developed to create an image of large areas on the seafloor effectively. This sonar device emits conical or fan-shaped pulses down towards the bottom of the sea across an extensive range perpendicular to the path the sensor follows through the water. Side imaging fish finders use two sonar beams which are located on both sides of the boat.

The two sonar beams are positioned in a right angle direction of the path of the boat to cover about 300 feet of water roundabout. The majority of SI sonar could be operated at two frequencies of 800 kHz and 455 kHz. And will look down beneath the side of the boat and projects up to 240 feet with 440 foot.

As the name suggests a side imaging fish finder is basically a sonar device used for finding fishes under the water. You can have the best utilization of your time on the water. It uses sonar technology coming with a particular transducer.

You just need to set it on the outside of the boat transoms to have a view of the shoal of fishes. The utility aspect of side scan fish finder. The side scan fish finders normally present the image on split-screen with a dark band in the center which is the turbulent water underneath your own boat.

The side imaging finders show an image in two dimensions and you have to interpret them. Shadow is the most helpful factor when interpreting side scan sonar not so with downward looking sonar. A shadow tells you if an object is in the water column on the bottom starting to bury is solid like a rock or hollow like a lobster trap how high it is from the bottom and it also tells you the general shape of an object.

Humminbird Side Imaging sonar uses a razor-thin beam to take a sonar snapshot of the area up to 400 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.

In this video I explain how to identify fish on a side imaging fish finder. I give instructions and tips on how to pick out bass on siding imaging sonar s.

Heres a visual representation that really helped me understand how it works. The darkness on your screen is right underneath your boat as your device scans out towards the sides. So if you see part of a school fish on one side of the screen as well as.

Lowrance side imaging fish finder. The difference between down imaging and side imaging is that in down imaging we make use of one sonar beam and that beam looks directly towards the bottom whereas inside imaging we make use of two beams and these beams are slightly angled upwards on both sides. As this side imaging technology makes use of two.

Types of Kayak Fish Finders Down Scanning. Shoots a high-frequency narrow-beam signal to create a photo-like image of the bottom. Offers incredible detail of structure and vegetation.

Uses the same signal as down scanning sonar but shoots to the side to create an image of bottom structure and fish to the left and right of the kayak. But side imaging sonar scans up to 360 feet to each side of the boat which is depicted by the green band stretching across the entire graphic. The crab trap and speckled trout cannot escape detection.

When side imaging is rendered on your graph or fish finder or. Throughout this document the term side scan will refer to all side looking bottom imaging sonars. Please also note the matrix and discussion do not include the depth sounder echosounder Down Imaging or fish finder sonars present on most hull mounted systems.

Understanding side imaging takes some getting used to so. Do you know how to read side imaging. Do you know what its for or how to use it to catch more fish.

Imaging Sonar Imaging sonar pings a very narrow beam either to the sides Side Imaging or straight down Down Imaging when your boat is moving the sonar returns stack on each other creating a realistic image of the lake bottom and shows fish. Fish finders that have side imaging allows you to scan the water horizontally on each side of your boat. This gives you the ability to scan a larger area more quickly.

Side imaging is most effective when your boat is moving at 3-5 mph. One thing that is super cool about side imaging is that a lot of times you can see the fishs sonar shadow. Basically the fish is up off the floor of the lake and suspended somewhere in the water column.

Therefore the fish blocks part of the sonar beam and creates a sonar shadow on the floor of the lake on your fish finder screen.
