INSTALLATION
Planning & Positioning
Before beginning work it is important to plan out the installation, taking note of:
The vessels hull design.
Location for the transducers and control box.
Cable runs and power supply.
Location of Control Box
The control box is sealed and water resistant so can be installed in the most convenient location, preferably
above the water line.
The length of cables to the transducers should be taken into consideration for the location of the control box
.
Hull Construction
Ultrasonic sound waves will only work properly on
fi
breglass, aluminium and steel hulls.
The system is not suitable for wooden hulls.
Hull Mounting
Transducers must be bonded directly to the hull of the boat. Special care must be taken to ensure that they
are not bonded to a false
fl
oor, cavity, over a keel, or on the inner layer of a balsa/foam cored boat.
A direct connection to the hull may require removing any spacing or other layer such as a sandwich foam or
balsa core.
If working with steel or aluminium, be sure not to connect over welds or seams in the material.
Obstructions
Avoid mounting transducers close to any objects such as stringers, bulkheads, water tanks, fuel tanks,
transoms, depth
fi
nder and
fi
sh
fi
nder.
Ideally, they should be 30 cms away from these areas for the system to operate most effectively.
.
Transducer Positioning
The diagrams below show the general optimum areas for mounting transducers, since every vessel is
different. The illustration should be used as a general guide only.
On smaller power craft under 10m, the transducer should be positioned in the close proximity of the propeller
and shaft to help protect these isolated parts.
Transducers should be
fi
tted onto a solid part of the hull, see under hull mounting above.
They should also be approximately 30cms off the centre line.
For stern drive units, transducers should also be approximately 10 to 13cms forward of the transom.
These measurements are a guide only, but the surrounding structures in the vessel will determine the
fi
nal
position.
