Filter provides an advanced level of control over the amount of detail
visible on-screen and the sensitivity of the unit. You can choose the setting
that works best for your style of use.
With Filter set to
OFF
, the
128
displays increased
detail, showing more thermoclines, structure, fish
and even your bait when it falls within the sonar
cone. However, this extreme sensitivity requires
you to optimize the installation of your unit and transducer so that “noise”
generated by a moving boat is not picked up by the fishfinder.
With Filter set to
ON
, excessive clutter often caused by interference from other
fishfinders, your boat‘s engine, or from noise generated by the hull at high speeds
is reduced in the display. This provides a cleaner image on the display in most cases.
With the Filter menu selected in the C

window, use the
R
ANGE
±
knob to select the setting for your boat. When finished, press
