Installation of Transducers (Option)

This equipment can use thru-hull, transom or
inner hull mounted transducers. Select a
transducer mounting type according to the
ship's type. The optional inner hull mounting
kit (type: 22S0191) is required for inner hull
mounting. For details about inner hull mount-
ing, see the installation instructions supplied
with the inner hull mounting kit.
Transducer mounting location
The performance of this fish finder is directly related to the mounting location of the
transducer. The installation should be planned in advance, keeping the length of the
transducer cable and the following factors in mind:
• 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 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 your 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.
