Zoom Adjustment

Range—sets the display depth range used for viewing. The unit

can be set to automatically track the bottom or set to a user-

speciﬁed depth range. Auto Mode displays the most information

possible while continuously showing the bottom.
Zoom—used to quickly select a display zoom scale or split

the display. When a scale other than

No Zoom is selected, the

Adjustment Menu displays a new selection labeled View. The

Zoom setting is divided into six display levels:

4X Split Zoom Display (Dual Frequency Mode)

• 2X Split—shows two reduced-size sonar pictures at the

same time. The right half of the display screen shows the

complete sonar picture at its original scale. The left half

shows a portion of the original picture at 1/2 depth scale.

• 2X Zoom—displays the 2X zoomed picture on the full

screen and does not show the original depth scale.

• 4X Split—shows two reduced pictures; the right at the

original depth scale and the left at 1/4 the original depth

scale.

• 4X Zoom—displays only the 4X zoomed picture on the full

screen. However, if Dual Frequency Display is set to Split,

then a 50/200kHz split screen appears.
