Depth Line

Adjustment

Noise Reject—helps ﬁlter unwanted noise from the graph. The

Noise Reject tool can be turned Off, set to Normal (automatically

adjusts for optimum viewing), or to a ﬁxed 1-100% setting. When

setting the Noise Reject tool: the HIGHER the noise rejection

setting, the less likely the unit is to NOT show ﬁsh or structure.

To turn the Noise Reject Off, press the ROCKER Down until the

setting bar is all the way at the bottom of the range and reads Off.

Noise Reject

Adjustment

Scroll—adjusts the rate that the graph scrolls from right to left.

If you are sitting still or the graph is moving too fast, slowing the

scroll rate or pausing it can be beneﬁcial.
