What is a Vexilar?
A Vexilar is a brand name for a type of fish finder or sonar device that is used for locating fish underwater. Fish finders work by emitting sonar signals into the water and measuring the time it takes for the signals to bounce back from the bottom or from any fish in the water. The data is then displayed on a screen, which can show the depth of the water, the structure of the bottom, and the location of any fish. Vexilar fish finders are popular among fishermen and are used for both recreational and commercial fishing.
