Active sonar

The use of sound waves reflected off objects or emitted directly by a source of sound to detect or measure the distance, size, speed, direction, or other characteristics of a remote object.

Imaging Types

Down Imaging

Down Imaging sonar systems shoot sound waves out in a cone-shaped pattern in front of the boat. The sound waves reflect off of objects in the water and are sent back to the fish finder.

A display on the fish finder then shows an image of the object that the sound waves bounced off.

Side Imaging

Side Imaging sonar systems work by sending sound waves down to the bottom of the water. Instead of bouncing back up, these waves are reflected horizontally near the surface.

The display on the fish finder then provides an image of objects that are near the bottom or on the surface.

GPS Mapping Technology
