CONTROL HEAD INSTALLATION

You have two choices for mounting your 900 Series™ control head:

Gimbal mounting, where you use a surface on the boat, such as the dash, to mount the control head so that it can be tilted up or down, or

In-dash mounting, where you cut a hole in the dash in order to allow the control head to be recessed into the dash, and the control head cannot be moved after mounting.

GIMBAL MOUNTING THE CONTROL HEAD

If you are gimbal mounting the Humminbird® 900 Series™, you can pre-assemble the unit in order to plan the best mounting location.
