INSTALLATION
You will need to find a place to mount the unit that will make it
easy to view and reach. You must provide the unit with power
and mount the transducer and temp sensor in an effective loca-
tion.
Mounting the Unit
Find a convenient place to mount
the unit. Make sure that there is
plenty of room for the unit to tilt
freely without the cables binding or
stretching behind the unit. Once you
have found the spot, remove the unit
from the gimbal bracket and securely
attach the bracket to the mounting surface. The screws provided
are for wood/carpet or dash mounting applications. If you want
to use an optional removable swivel bracket, be sure it’s able to
support the weight of this unit.
A Decorative Wire Cover has been included to help make your
rigging job look good. Use this to cover up the large hole you’ll
need to drill to fit the transducer, temperature probe, and power
connectors through.
Connecting the Power
Plug the 2 pin connector into the back of
the unit. Find the closest source of 12 volts
and route the cord to it. Keep the cord
away from sharp metal edges and avoid
tight places where the cord may get crushed. Connect the white
wire to positive and the black wire to negative. If the cord pro-
vided is not long enough, more can be added. Use 18 gauge wire
minimum. Install a 2 amp in-line fuse, placed in the positive line,
as close to the power source as possible, to protect against shorts
in the wiring.
MOUNTING THE TRANSDUCERS
The transducer mounting method will depend on which version
of the Edge
3
you purchased. In either version, it is important to
mount the two transducers as close together as you can. This
will insure your Edge
3
gives you the information it was design
to offer.
• LC-507C TM - Transom Mount Transducers
• LC-507C ETM - Trolling Motor Mounted Transducers
• LC-507C IH - In-Hull Mounted Transducers
Transom Mounting
Locate the transducers and bracket
hardware. Each transducer has a
mounting bracket assembly which
includes;
2 Angle Brackets
4 Bracket Screws
4 Washers
4 Nuts
4 Mounting Screws
Attach the bracket to the transducer as shown in Figure 5. The
flanges of the bracket normally point outward, away from the
transducer. If mounting space is tight, you can reverse the angle
brackets and face the flanges inward.
Locate a spot for each transducer simi-
lar to the one shown. If your boat hull
has a significant rise (more than 10°),
you should mount the transducer so the
bottoms are parallel to the water line.
If your boat hull is level, or has only a
small rise, you should keep the bottom
of the transducers parallel with the hull
