INSTALLATION OVERVIEW

The 405SX consists of two primary components to install: the control head and the transducer.

The control head contains the sonar transmit and receive circuitry, as well as the user controls and display. It should be installed in a location that provides access to the controls and visibility while in use. The control head mounts on a quick disconnect mounting system that swivels and tilts, providing flexibility for viewing from almost anywhere on the boat.
