TRANSDUCER WETTING
Immediately before your vessel, thoroughly wipe the face of the transducer with a detergent type
liquid soap. This reduces the amount of time required for the transducer to establish good contact
with the water. If this procedure is not followed it may take several days for the complete “wetting”
to occur, resulting in reduced performance of the instrument.
There are a variety of transducers available for use on the many styles of boats available and the
preference of the boat owner. The three most popular styles are:
●
TRANSOM MOUNT: Ideal on boats with outboard engine or on I/O driven boats installed on
the stern of the boat)
●
THROUGH THE HULL: Installation is ideal for boats with Inboard engine(s)
●
INSIDE THE HULL: Often called Shoot Through Transducer can be used effectively if
procedures for installation are followed carefully.
“STYLE” OF THROUGH-THE-HULL TRANSDUCERS:
Transducer manufacturers build many different styles of transducers. The two most popular styles
of Through the Hull transducers are Low Profile types which typically are 1 3/4” or 2” in diameter
of Stem Type transducers which typically have a ¾” pipe thread and require a fairing block to level
it.
“MATERIAL” OF THROUGH-THE-HULL TRANSDUCERS:
The two most popular materials used are nylon and bronze.
●
WOODEN BOATS require the use of a bronze transducer or bronze fittings due to the fact
that when the boat is out of the water, the wood will dry out. When the fitting is installed and
the boat returned to the water, the wood will swell and possibly crack a nylon type of
transducer. Therefore, bronze is recommended for all wooden boat applications.
●
LARGER FIBERGLASS BOATS often prefer bronze transducers and fittings due to the size
of the boat and the total number of fittings used in the installation.
NYLON OR BRONZE - LOW PROFILE TRANSDUCERS
Ideal for high speed sport boats and sailboats, this style of transducer is designed to be mounted
flush against the hull without a fairing or leveling block. The hull deadrise angle must not exceed
15° in order to use this transducer fitting.
●
SAILBOATS: Normally a maximum beam amidships or in front of the keel.
●
POWERBOATS: Off centerline, 6”-12” and before the first lifting strake (flat area). Do not
install it on a lifting strake since this is the area where air bubbles travel from the bow to the
stern in order to provide a smooth ride.
