necessary.
You are now ready to install the transducer. Find the section that refers to
your specific transducer installation method.
Transducer Installation Overview
Proceed to the installation section that matches your transducer type. Your
choices are as follows:
• 858c, 958c: DualBeam PLUS™ (XNT 9 20 T), Transom Mount
• 858c, 958c: DualBeam PLUS™ (XNT 9 20 T), Inside the Hull Mount

• All units: Trolling Motor Transducer Installation
NOTE: Due to the wide variety of hulls, only general instructions are presented
in this installation guide. Each boat hull represents a unique set of requirements
that should be evaluated prior to installation. It is important to read the
instructions completely and understand the mounting guidelines before
beginning installation.
1a. If a fuse terminal is available, use crimp-on type electrical
connectors (not included) that match the terminal on the fuse
panel. Attach the black wire to ground (-), and the red wire to
positive (+) 12 VDC power. Install a 3 amp fuse (not included) for
protection of the unit. Humminbird® is not responsible for over-
voltage of over-current failures.

1b. If you need to wire the control head directly to a battery, obtain
and install an inline fuse holder and a 3 amp fuse (not included)
for the protection of the unit. Humminbird® is not responsible for
overvoltage or over-current failures.
NOTE: If the included transducer will not work for your application, you may
exchange it, NEW and UNASSEMBLED, with mounting hardware included, for
a transducer appropriate for your application - often at very little or no charge
depending on the transducer. Call the Humminbird® Customer Resource
