When selecting the transducer type and hull location
for the transducer(s) keep in mind the primary rule for
transducer operation. This is: the transducer can
function as long as it has an unobstructed forward
view and has smooth flowing non-aerated water
surrounding it.
♦ Do not cut or splice your phased array transducer
cable or removing the 9-pin connector as it will
void the transducer warranty.
♦ On both the thru-hull and transom mount trans-
ducers the blunt end is the forward end! See
sketch at right.
♦
♦ ♦
♦ If you need a longer length cable than comes
with the transducer (30’), then purchase the
optional extension cables, Interphase Part # 04-
0014-008R for 30’ or 04-1014-007R for 10’
lengths. Total transducer cable lengths over 60’
are not recommended as they will decrease the
effective power and depth range.
♦ Choose a location where there is the least
amount of acoustic noise, air bubbles or
turbulence caused by the boat’s movement. The
transducer should not be located nearby or
especially directly behind the propeller.
♦ Choose a location where the transducer can be
mounted so that it will be level to the water’s
surface and will not be tilted to either side.
Otherwise the transducer will not scan from the
surface ahead to directly beneath the boat.
♦
DO NOT install a bronze transducer housing
directly into an aluminum or steel hull because
electrolytic corrosion will occur. Consult your
boat-yard for more information on how to
properly install transducers into these types of
hulls.
♦ DO NOT allow any solvents i.e. gasoline, ace-
tone to come in contact with the transducer head
unit as this may dissolve the urethane material.
In addition, DO NOT force the cable by pulling
on it. This may cause damage to the internal
transducer wiring.
