7Transducer Selection and Installation
Be sure to turn the power off before starting the installation. Further, it is highly
recommended that you keep power off while you’re performing the installation. If
power is left on or turned on during the installation, fire, electrical shock, or other
serious injury may occur. Be sure to ground the equipment to prevent electrical shock
and mutual interference. Be sure the transducer outputs are tied together before
handling to avoid electrical charge build-up.
Be sure to use a 5 Amp fuse. Using the incorrect fuse can result in fire or damage to
the Network Sounder
Mounting the transducer requires drilling holes through the hull; make sure the
installation does not cause the vessel to leak.
A thru-hull installation should be performed by a professional installer. Do not
attempt this unless you are fully qualified. Do not perform a thru-hull installation of
the transducer when the vessel is actually in the water.
Immediately after installing the transducer, be sure to check for leaks, and don’t
leave the vessel in the water for more than three hours before checking it again.
Northstar assumes no responsibility for improper or incorrect installation of a
transducer.
The following basic setup information is not a substitute for the installation
instructions provided by the transducer’s manufacturer. To ensure that you meet all
critical installation parameters, be sure to read and follow all of the requirements in
their instructions. Northstar assumes no responsibility for improper installation.

The following basic setup information is not a substitute for the installation instructions
provided by the transducer’s manufacturer. To ensure that you meet all critical installation
parameters, be sure to read and follow all of the requirements in their instructions.
Northstar assumes no responsibility for improper installation.
Selecting the best location for the transducer
The two most common problems with echo sounder installations stem from electrical
noise and cavitation. Either of these situations can produce poor performance.
Electrical noise occurs when the transducer cable is routed too closely to noise-
producing electronics, such as alternators, AC generators, radars, etc. To avoid
problems with noise, route the transducer cable by itself (not in a bundle) and away
from other wires or cables and the engine.
Cavitation can occur at high speeds. During cavitation, bubbles form between the
transducer and the water. When this happens, the transducer can’t get its energy into
the water properly and won’t be able to detect any echoes. To avoid cavitation,
choose a mounting location with good water flow all around it at all speeds.
Before any drilling or cutting takes place, carefully choose a mounting location for the
transducer that meets the following criteria, depending on the type of vessel:
the transducer is more than four feet away from the Northstar
navigator and other similar equipment, to prevent mutual electrical
and magnetic interference
the transducer and its cable are as far as possible from other electrical
cables
there is space above the transducer for the transducer’s stem,
housing, and cable
the path for running the transducer’s cable is reasonably direct—keep
in mind that the transducer cable is 33 feet long (10 meters). To
prevent damage, coil any excess cable and secure it
water turbulence and noise are minimal, decreasing the amount of
bubbles passing over the transducer face
the transducer isn’t behind hull irregularities or near eroding paint;
both indicate areas subject to turbulence
the transducer is as far as possible from the engine or propellers, and
inboard of the lifting strakes
the transducer always remains submerged and parallel to the water
surface
the transducer is easily accessible from inside the vessel for
adjustments and maintenance

20 Northstar 8000i 1 kW Network Sounder Installation Manual
the transducer’s ultrasonic beams aren’t obstructed by the keel,
propeller shafts, or any other part of the vessel the hull thickness falls
within the limits in Table 3 below (all dimensions are perpendicular to
the waterline):
Best Location for the Transducer
Displacement hull. A - Pressure waves
Planing hull - Outboard and I/O Planing hull - Inboard
Stepped hull Fin keel sailboat
Full keel sailboat
A flat-bottom hull provides the best environment for mounting the transducer:
It provides a horizontal surface and a constant water flow over the transducer, with
little turbulence (see Figure 2 for the recommended transducer incline angle). If the
vessel has a deadrise angle greater than 5 degrees, mount the transducer on a fairing
