Lowrance electronic Fish Finder manual Transducer Orientation and Fish Arches

3.Route the transducer cable alongside the trolling motor shaft. Use plastic ties (not included) to attach the transducer cable to the troll- ing motor shaft. Make sure there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the trans- ducer is ready for use.

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 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.
