Installation Overview
Use the following instructions to install the Sensor accessory on your boat. In
order to understand the installation requirements, we recommend that you
read the instructions carefully before you start the installation.
Required Supplies: In addition to the hardware included with your
Sensor accessory kit, you will need a drill, electrical tape, and an awl or
pencil. Depending on your installation requirements, you might also
need to purchase extention cables or a stem. See Section 1: Choose
the Mounting Location for more information.
1. Choose the Mounting Location
It is important to consider the following information when you choose a
mounting location for the Sensor:
• Interference: Do NOT mount the Sensor close to a VHF antenna or
within the active area of a radar. If the Sensor includes a compass
(AS GPS HS), do NOT install it near ferrous metals or near anything that
can create a magnetic field. Hardware and cables that handle large
currents, such as batteries and power cables, are also examples of
equipment that may cause interference.
• Reception: Mount the Sensor in an area that has full exposure to the
sky. The effective area of reception is 5˚ above the horizon.
• Surface: Whether the Sensor Cable will be routed down through the
mounting surface or to the side, or if your’re using a stem mount, the
mounting surface will influence how you install the Sensor. For details,
see Section 2: Install the Sensor.
• Cables: Test run the Sensor Cable from the chosen mounting location to
the Control Head. 10 ft (3m) extension cables may be purchased from
Humminbird® if your planned cable route exceeds 20 ft (6 m). Maximum
cable length, including extension cables, should not exceed 50 ft (16 m).
NOTE: To purchase extension cables, or other related accessories, visit our Web
