Vexilar 107 Pro - Manual (Page 10)

PORTABLE MOUNTING
An optional suction cup bracket can be
used to temporarily attach a transducer to the
transom or side of the boat. The cups should
be placed in a location where they will not be
torn off when the boat goes high speed, but
still just low enough to maintain the high speed reading.
The optional BK0044 suction cup mounting plate works
well for this application.
An arm assembly that clamps to the transom or side of
the boat can also be used to hold the transducer. Simply
attach the transducer to the end of the arm using cable ties
or tape. If the arm is constructed of metal tubing insulate
the transducer from the arm by wrapping electrical tape
around the arm. This prevents "ringing" which can be dis-
played as noise near the surface.
IN-HULL MOUNTING
Finding the best location for the transducer before
mounting is critical. Choose a flat smooth spot near the
center of the bilge and near the back of the boat. It is a good
idea to make a "test run" before you permanently install
the transducer. This makes sure that you can, indeed, get
a reading through your hull, and when the boat is on plane.
Put about a half inch of water in the bilge and hold the
transducer in the intended location. Move the transducer
around until you get the best reading. Mark the spot.
To install the transducer, clean the spot of mud and oil.
