Shoot-Thru-Hull Preparation; Hulls With Floatation Materials - Lowrance X510C Operation Instructions Manual

Transducer angles and their effects on fish arches.
If the arch slopes up – but not back down – then the front of the trans-
ducer 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 re-
move any oil film. Oil and dirt on the face will reduce the sensitiv-
ity or may even prevent operation.

Shoot-Thru-Hull Preparation

Hulls With Floatation Materials

The transducer installation inside a fiberglass hull must be in an area
that does not have air bubbles in the resin or separated fiberglass lay-
ers. 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. See the following figure.
