White Edge

The white edge function gives the seabed echo a white edge, making it easier to dif-
ferentiate bottom-feeding fish from the seabed itself.
Note 1: The white edge function is compatible with the internal fish finder, as well as
the following transducers and their software versions. Use of other transducers or soft-
ware versions is not recommended.
Transducer
BBDS1
DFF1
DFF1-UHD
DFF3
DFF-3D
Note 2: White edge is not available when a TZT9F or TZT14 is connected in the same
network with TZT2 series.
To activate the white edge function, do the following:
1. Open the Layers menu.
2. At [White Edge], tap the desired width for the white edge. The higher the number
the greater the width.
To deactivate the white edge function, tap [Off] at step 2 in this procedure.
Note: With the DFF-3D's triple beam display, white edge is available only with the
downward picture.
