| Determine the Transducer Mounting Position
The Side Imaging transducer has specific mounting requirements. Consider the following to find the
best mounting location for the transducer.
WARNING! Do NOT install the transducer in line with the engine intake.

1
The best mounting location for the transducer is aft midship, as close to the centerline of the
boat as possible.
2
Make sure nothing is in front, behind, or to the side of the transducer that is closer than 12"
(30.5 cm). The transducer should be mounted forward of the propellers on inboard boats, and
separated adequately from other transducers, strakes, rivet lines, or other protrusions on the
boat.
3
Deadrise: The transducer, when mounted, must be parallel with the waterline. If the selected
mounting location has a hull deadrise of 2 degrees or greater, the included leveling block should
be used to level the transducer housing and direct the sonar signal straight down.
4
The Side Imaging transducer must NOT have anything obstructing the 'view' of the side looking
beams. For example, nothing can be in the line of sight of these beams (not a hull, motor, or
other transducer, etc.)
NOTE: Side Imaging sonar is best performed at boat speeds from 2 to 6 mph, and it is not
recommended for high-speed operation (as gaps between strips of information can appear).
However, the transducer can support traditional 2D sonar and Down Imaging® sonar at higher
speeds. Rough seas and air bubbles can also affect the reading of the Side Imaging transducer.
5 Inside the Boat: There must be room to access the mounting location for installation and cable
routing. If you need to use the leveling block, make sure the inside surface of the hull is smooth
enough to seat the leveling block securely.
Installation Scenarios for Consideration:
Flat Hull, One Transducer: Locate a flat area on the bottom of
the hull, forward of where the propeller shaft comes out of the
hull. Make sure there is nothing lower than this location to the
right or left.
V-shaped Hull, Two Transducers: Install two thru-hull
transducers, one on each side of the V. Connect the transducers
with a Y-Cable.
Two Back Engines, Two Transducers: Install two thru-hull
transducers outboard from the dual engines. Connect the
transducers with a Y-Cable.
NOTE: Installations with two transducers require a Y-Cable (or
Splitter Cable), which vary based on the control head model. To
purchase a cable, visit our Web site at humminbird.com.

RECOMMENDED:
In the illustration, the transducer is
close enough to the centerline so that
the hull will not interfere with the Side
Imaging beams.

4
NOT RECOMMENDED:
In the illustration, the transducer is too
far from the centerline, and the hull is
blocking the Side Imaging beams.
