CHIRP Interference Rejection: Six settings keep competing sonar signals from cluttering your screen, providing a clear view in both sonar and flasher modes.
Adjustable Sonar Zoom: Hone in on fish, whether they are tight to the bottom, or suspended high in the water column. Utilize 2X zoom on the flasher screen, or up to 16X zoom on 2D sonar view.
