Transducer Orientation And Fish Arches; Shoot-Thru-Hull Preparation And Installation - Lowrance X47 Installation And Operation Instructions Manual

TRANSDUCER ORIENTATION AND FISH ARCHES

If you do not get good fish arches on your display, it could be because
the transducer is not parallel with the ground when the boat is at rest
in the water or at slow trolling speeds.

Transducer angles and their effects on fish arches.
If the arch slopes up – but not back down – then the front of the
transducer is too high and needs to be lowered. If only the back half of
the arch is printed, then the nose of the transducer is angled too far
down and needs to be raised.
NOTE:
Periodically wash the transducer's face with soap and water to
remove any oil film. Oil and dirt on the face will reduce the
sensitivity or may even prevent operation.
SHOOT-THRU-HULL PREPARATION
The transducer installation inside a fiberglass hull must be in an area
that does not have air bubbles in the resin or separated fiberglass
layers. The sonar signal must pass through solid fiberglass. A
successful transducer installation can be made on hulls with flotation
materials (such as plywood, balsa wood or foam) between layers of
fiberglass if the material is removed from the chosen area.
