A sidescan sonar uses high-frequency sound pulses that are bounced off the sea floor to create an image of the sea floor morphology shape) and show differences in seabed texture and substrate types. Typically, a sidescan sonar consists of two transducers mounted in a towed body or 'fish'.
Where can a side scan sonar be mounted?
hull
How does side scan sonar differ from regular sonar?
The primary difference is that the transducer broadcasts a very narrow beam, both straight down and side-to-side, instead of the traditional cone shape. This means the display is receiving a nearly two-dimensional signal, allowing for a much more detailed display image.19 Jun 2014
Does side imaging work in deep water?
Yes. The Side Imaging units will show detailed images of the bottom up to 150 feet deep. Also the side imaging can be used to scan an area of water up to 480 feet wide for suspended fish and baitfish regardless of the depth.
What is the difference between sonar and side scan sonar?
2.2 Side-Scan Sonar. Side-scan sonar is a category of sonar system that is used to efficiently create an image of large areas of the seafloor. Side-scan data are frequently acquired along with bathymetric soundings and sub-bottom profiler data, thus providing a glimpse of the shallow structure of the seabed.
How is multibeam technology different from sonar?
Unlike single beam sonar, which uses just one transducer to map the seafloor, a multibeam sonar sends out multiple, simultaneous sonar beams (or sound waves) at once in a fan-shaped pattern. Multibeam collects two types of data: seafloor depth and backscatter.
What is a multibeam sonar system?
Multibeam sonar is a common offshore surveying tool that uses multiple sound signals to detect the seafloor. Because of its multiple beams it is able to map a swath of the seabed under the ship, in contrast to a single beam sonar which only maps a point below the ship.
Can you see fish on side imaging?
View multiple Humminbird sonar and imaging technologies at once for a complete picture. Here, we can see trees, weeds, and fish to the right side of the boat as the depth falls off. Enable range lines to help determine the distance between your boat and fish, structure or weeds.
How can you tell which side scan your fish is on?

Do fish finders actually show fish?
A fish finder is a highly effective tool that will allow you to see fish and structure you never knew were there; however, one slight misstep in the buying process can make your new device ineffective and, at times, they will not show you the complete picture.
When did side imaging come out?
In 1963 Dr. Harold Edgerton, Edward Curley, and John Yules used a conical-beam 12 kHz side-scan sonar to find the sunken Vineyard Lightship in Buzzards Bay, Massachusetts.
Who uses side scan sonar?
Side-scan sonar is a category of sonar system that is used to efficiently create an image of large areas of the seafloor. This tool is used for mapping the seabed for a wide variety of purposes, including creation of nautical charts and detection and identification of underwater objects and bathymetric features.
