Setting up and Using Sonar > Using the Sonar Page

Depth Line—adds a horizontal depth line across the screen that is

used to measure the depth of underwater objects. The depth of the

line appears in a box on the right side of the line. Press up or down

on the ROCKER to move the line on the Sonar Page.

Noise Reject—helps ﬁlter unwanted noise from the Sonar Page.

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

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

setting the Noise Reject, remember that a higher noise rejection

setting is less likely to show ﬁsh or structures.

Resizing the Split Screen

You can adjust the way the split screen is shown. This option is only

available when a zoom scale other than No Zoom is selected.

To resize the Sonar Page split screen:

1. From the Sonar Page split screen, press MENU.

2. Using the ROCKER , highlight Size Split, and press ENTER.

3. Move the horizontal double-arrow left or right using the ROCKER

until the vertical width line shows, then press ENTER.

4. If you want to cancel this operation, press QUIT or press MENU,

highlight Stop Resizing, and press ENTER.

Using the Pointer on the Sonar Page

You can show the pointer (arrow) to reference sonar items and

mark underwater waypoints. This makes it easier to ﬁnd and use an

object such as a stump for a future ﬁshing location. When using this

feature, the Sonar Page pauses. The depth continues to update while

the screen pauses, but the unit does not show any new sonar data

until the Sonar Page resumes scrolling.

To mark an underwater waypoint:

1. From the Sonar Page, press MENU, highlight Show Pointer, and

press ENTER.

2. Use the ROCKER to move the pointer to the location you want to

mark. Press ENTER. The New Map Waypoint Page appears.

3. To change the name, symbol, or depth, highlight the appropriate

ﬁeld and press ENTER. Make your changes, and press ENTER

when done.

4. When ﬁnished, highlight OK, and press ENTER.

5. To return to the standard Sonar Page, press QUIT; or press

MENU, highlight Hide Pointer, and press ENTER.
