Lowrance lcx-112c Operating Guide

Sonar Operations

As you can see from the quick reference on the previous page, basic operation

is easy, right out of the box. If you are a sonar novice, try operating the unit
with the factory defaults until you get a feel for how it's working.
As you're learning the basics, there is one setting you might want to tinker

with from time to time — Sensitivity.
Sensitivity controls the unit's ability to pick up echoes. If you want to see

more detail, try increasing the sensitivity, a little at a time. There are

situations when too much clutter appears on the screen. Decreasing the
sensitivity can reduce the clutter and show the strongest fish echoes, if fish

are present. As you change the sensitivity setting, you can see the difference

on the chart as it scrolls.

These figures show results of different sensitivity levels on the same

location. Fig. 1: Sensitivity at 88 percent. Typical of full auto mode. Fig.

2: Sensitivity set at 75 percent. Fig. 3: Sensitivity set at 50 percent. Fig.

4: Sensitivity set at 100 percent.
