1.2 Network Sounder
The network sounder can be installed on a desktop, deck or on a bulkhead. When selecting a mounting location for the network sounder, keep the following in mind:
• The temperature and humidity should be moderate and stable.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the unit away from electromagnetic field-generating equipment such as
motors and generators.
• Leave slack in cables for maintenance and servicing ease.
• A magnetic compass will be affected if the network sounder is placed too close to it.
Observe the compass safe distances noted in the safety instructions to prevent disturbance to the magnetic compass.
• Fasten the network sounder to the mounting location with four self-tapping screws
(4×20).

1.3 Transducer 520-5PSD, 520-5MSD
1.3.1 Mounting location
.The performance of this sounder is directly related to the mounting location of the
transducer, especially for high-speed cruising. The installation should be planned in
advance, keeping the standard cable length and the following factors in mind:
• When the boat has a keel, the transducer should be at least 15-30 cm away from it.
Typical thru-hull mountings are shown in the figure on the next page.
• Air bubbles and turbulence caused by movement of the boat seriously degrade the
sounding capability of the transducer. The transducer should, therefore, be located
in a position where water flow is the smoothest. Noise from the propellers also
adversely affects performance and the transducer should not be mounted nearby.
The lifting strakes are notorious for creating acoustic noise, and these must be
avoided by keeping the transducer inboard of them.
• The transducer must always remain submerged, even when the boat is rolling,
pitching or up on a plane at high speed.
• A practical choice would be somewhere between 1/3 and 1/2 of the boat's length
from the stern. For planing hulls, a practical location is generally rather far astern,
so that the transducer is always in water regardless of the planing attitude.

1.3.3 Installation procedure
1. With the boat hauled out of the water, mark the location selected for mounting the
transducer on the bottom of the hull.
If the hull is not level within 15° in any direction, fairing blocks made out of teak
should be used between the transducer and hull, both inside and outside, to keep
the transducer face parallel with the water line. Fabricate the fairing block as
shown below and make the entire surface as smooth as possible to provide an
undisturbed flow of water around the transducer.
The fairing block should be smaller than the transducer itself to provide a channel
to divert turbulent water around the sides of the transducer rather than over its
face.

Saw along slope of hull.
Construction of fairing block
2. Drill a hole just large enough to pass the threaded stuffing tube of the transducer
through the hull, making sure it is drilled vertically.
3. Apply a sufficient amount of high quality caulking compound to the top surface of
the transducer, around the threads of the stuffing tube and inside the mounting
hole (and fairing blocks if used) to ensure watertight mounting.
4. Mount the transducer and fairing blocks and tighten the locking nuts. Be sure that
the transducer is properly oriented and its working face is parallel to the water line.

Note: Do not over-stress the stuffing tube and locking nuts through excessive tightening, since the wood block will swell when the boat is placed in the water. It is suggested
that the nut be tightened lightly at installation and retightened several days after the
boat has been launched.

1.4 Transducer 525-5PWD (transom mount)
This type of mounting is very commonly employed for outboard motor boats. Do not
use this method on an inboard motor boat because turbulence is created by the propeller ahead of the transducer.
There are two methods of installation: flush with hull (for flat hulls) and projecting from
hull (for deep V-hulls).
Flat Hull
Transom mount transducer mounting locations
1.4.1 Installation for flat hulls
A suitable mounting location is at least 50 cm away from the engine and where the
water flow is smooth.
1. Drill four pilot holes in the mounting location.
2. Attach the transducer to the bracket with self-tapping screws (supplied).
3. Adjust the transducer position so the transducer faces right to the seabed.
Note: If necessary, to improve water flow and minimize air bubbles staying on the
transducer face, incline the transducer about 5° at the rear. This may require a
certain amount of experimentation for fine tuning at high cruising speeds.
4. Fill the gap between the wedge front of the transducer and transom with epoxy
material to eliminate any air spaces.
