The network sounder can be installed on the deck or on the bulkhead. When selecting a
mounting location for t he 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 placed too close to the
magnetic compass. Observe the following compass safe distances to prevent
disturbance to the magnetic compass:
a) Standard com pass: 0. 80 m eters
b) Steering compass: 0.55 meters
Mounting procedure
Fasten the network sounder to the mounting location with four tapping screws (4 x 16).
Note: Do not install the equipment where it may get wet from rain or water splash.
Waterproof level is IPX2 (IEC 60529).

1.2 Thru-hull Mount Transducer 520-5PSD, 520-5MSD
Transducer mounting location
This type of mounting provides the best performance of all, since the transducer protrudes
from the hull and the effect of air bubbles and turbulence near the hull skin is reduced.
When the boat has a keel, the transducer should be at least 30 cm away from it. Typical
thru-hull mountings are shown in the figure on the next page.
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 (8 m) and the following factors in mind:
• Air bubbles and turbulence caused by movem ent 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 m ounted 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 ast ern, so that the
transducer is always in water regardless of the planing attitude.

Procedure for installing the thru-hull mount transducer
1. With the boat hauled out of the water, mark the location selected for mounting the
transducer on the bottom of the hull.
2. 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 t he transducer itself to provide a channel to
divert turbulent water around the sides of the transducer rather than over its face.

Figure 1-6 Construction of fairing block
3. Drill a hole just large enough t o pass the threaded stuffing tube of the transducer
through the hull, making sure it is drilled vertically.
4. Apply a sufficient amount of high quality caulking compound to the top surface of the
transducer, around the threads of the st uffing tube and inside the m ounting hole (and
fairing blocks if used) to ensure watertight mount ing.
5. 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 t ube 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 installat ion and retightened several days after the
boat has been launched.

1.3 Transom Mount Transducer 520-5PWD,
Optional Transom Mount Triducer 520ST-PWD
This type of mounting is very commonly employed for outboard motor boats. Do not use this
method on an inboard mot or 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
Figure 1-7 Transom mount transducer mounting locations
Deep V -hull
Installing the transom mount transducer flush with hull (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 t r ansducer to the bracket with tapping screws (supplied).
3. Adjust t he t r ansducer 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.

Figure 1-8 Transom mount transducer, mounting flush with hull
Installing the transom mount transducer projecting from hull (for
deep-V hulls)
This method is em ployed on deep-V hulls and provides good perf ormance because the
effects of air bubbles are minimal. Install the tr ansducer parallel with water surface; not
flush with hull. If the boat is placed on a trailer care must be taken not to dam age the
transducer when the boat is hauled out of the water and put on the trailer.

Transducer preparation
Before putting the boat in water, wipe the face of the transducer thoroughly with a detergent
liquid soap. This will lessen the time necessary for the transducer to have good contact with
the water. Otherwise the time required for com plete “saturation” will be lengthened and
performance will be reduced.
Note: Do not paint the transducer. Performance will be affected.

Necessary tools
You will need the following tools:
• Sandpaper (#100)
• Silicone sealant
• Silicone grease
Remarks on installation
• Turn off the engine and anchor the boat while installing the equipment.
• Install the transducer in the engine room.
Selecting the mounting location
Keep the following points in mind when selecting a mounting location:
• The mounting location should be where the hull is of single-hull thickness and is void of
air or flotation mat erials ot her than solid fiberglass between the transducer face and the
water.
• Do not place the transducer over hull struts or ribs which run under the hull.
• Avoid a location where the rising angle of the hull exceeds 15°, to minimize the effect of
the boat’s rolling.
• You will finalize the mounting location through some trial and error. The procedure for
1. Clean the transducer face to remove any foreign material. Lightly roughen the
transducer face with #100 sandpaper. Also, roughen the inside of the hull where the
transducer is to be mounted.
2. Warm the silicone sealant t o 40°C before usage to soften it. Coat t he transducer face
and mounting location with silicone sealant.
