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.
