A Guide To The Sonar Fish Finder

Fishfinders have made angling more interesting for professional anglers as well as for the novice anglers. Latest marine technology makes sure that you get the best features to grab more fish in less time. Many advanced technologies have been introduced in the past few years, to make fishing more fun and interesting. Sonar technology is one of them. Sonar actually stands for the sound. Sonar waves are a kind of sound waves that a transducer, mounted on the transom of the boat, sends deep into the water.
These sonar waves travel down into the water in the form of a beam angle. The purpose of sonar technology is to provide you with the best and life-like images from underwater. Anything that comes in connection to this beam angle, a transducer collects that sonar reading and displays it on the Fishfinder’s LCD.
Fishfinders come with different types of sonar beams. Some have single or dual, while many come with multiple sonar angles to provide you the best underwater experience.

Types of Sonar

Single and dual beam sonar that works on two levels (narrow & wide) to identify the target.
Down imaging Sonar works to give you 3D images of what is exactly under the boat. This sonar beam is quite a thin slice of high-frequency sonar waves.
Side Imaging Sonar covers both sides of your boat. These two beams on both sides create a photographic image of the underwater terrain including fish and structures.
