General Considerations
The orientation of the mounted transducer(s) is criti-
cal to the performance of the PC/View. The lower
diagram at right shows the proper orientation for
both the transom-mount and thru-hull transducer(s).
For all three types of transducers, the broader,
rounded or blunt side must point forward.
It is also important to think carefully about the loca-
tion of the transducer(s) before proceeding. Consider
the following:
1) The transducer(s) should be located where there
is the least amount of acoustic noise, air bubbles
or turbulence caused by the boat’s movement.
The transducer(s) should not be located near or
especially directly behind the propeller.
2) The transducer(s) must be mounted so that it
will be level with the water’s surface and will
not be tilted to either side.
3) The transducer(s) must always remain sub-
merged, regardless of the speed of the boat.
4) The transducer(s) should not be mounted where
it could be damaged by underwater obstacles or
when loading the vessel on a trailer.
5) DO NOT locate the transducer(s) in the ex-
treme bow of the boat where it will be subject to
intense turbulence as the boat pounds through
the water.
6) DO NOT locate the transducer(s) directly be-
hind any hull protrusion which will cause the
water to be turbulent when it reaches the trans-
ducer(s) or which will obstruct the transducer’s
forward looking view. For displacement-hull
power and sail boats, the thru-hull installation is
usually required.
7) Transducer cable(s) will need to be routed to the
Acoustic Interface Module. If you need trans-
ducer cable lengths greater than the standard
30’ length, order
two 30’ extension cables
(Interphase Part # 04-0014-008).
