Transducer mounted on trolling motor, side view.

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.

Transducer aimed

too far back

Transducer aimed

too far forward

Proper transducer angle
