Transducer Installation
The PC/180 uses three 8-element phased transducer
arrays (a total of 24 elements) configured in two sep-
arate through-the-hull (thru-hull) transducers. The
port side transducer includes a single horizontally
scanning array and the starboard side transducer in-
cludes a horizontally scanning array and a vertically
scanning array. The arrays are "potted" in a smooth-
surfaced plastic material that is acoustically transpar-
ent. DO NOT allow any solvents (i.e. gasoline,
acetone) to come in contact with the transducers
as this may dissolve the plastic housing.
Proper performance of your PC/180 is very depen-
dent on a good transducer installation and normally,
thru-hull installations are performed by a profes-
sional in a boat haul-out facility. We strongly sug-
gest you seek professional assistance before attempt-
ing to mount these thru-hull transducers.
The Transducers
The two PC/180 transducers are designed to be
mounted on opposite sides of the vessel's keel. Al-
though similar in appearance, the two transducers
operate differently and it is important that they be
mounted on the proper side of the vessel's keel.
Mount the Port-Side transducer on the port side of
the keel (the left side of the hull, looking forward
from the stern), and mount the Starboard-Side
transducer on the starboard side of the keel (the right
side of the hull, looking forward from the stern).
The Port and Starboard transducers can be identified,
as shown in the diagram at right, by the fact that the
Starboard-side transducer is slightly larger and has
two cables compared to the Port-side transducer's
single cable. In addition, each cable has a small la-
bel approx. 6" from the connector which identifies it
as the PORT HORZ, STBD HORZ or STBD VERT.
(Horz stands for Horizontal direction and Vert stands
for vertical direction.)
