Humminbird LCR 3D - Manual (Page 27)

The diagnostic function is also very helpful during troubleshooting to determine where a
problem in the system lies. A "weak" beam is usually caused by an improper sensor installation,
however, if your sensor is mounted outside the hull, the problem is most likely in the sensor or the
LCR 3D itself.
