To calibrate the water speed:

1. On the

Sonar tab, press the Cal Water Spd soft key.

2. Bring the boat to cruising speed. Both the top ground and uncalibrated

water speeds are shown at the bottom of the calibration window. Note your

top speed, stop the boat, and press

ENTER.

3. By default, the top ground speed automatically appears in the

“What

was your top water speed?” field. If a ground speed is not available,

the top uncalibrated water speed is used instead. If the new speed is

correct, highlight

OK, and press ENTER. If you want to manually enter

a calibration, press

ENTER on the speed field, enter a new speed, and

press

ENTER.

Graph Sub Tab

Use the Graph sub tab to select the color scheme, fish symbols, and scale.

The available Graph sub tab options are:

Color Scheme—sets the colors for the Sonar and Flasher Pages.

• Fish Symbols—sets how the Sonar Page interprets suspended targets

and background information. If you select a fish symbol, the

GPSMAP 2206/2210 identifies some returns for you by replacing

them with fish symbols (in large, medium, and small sizes based on the

size of the sonar return). If you are using dual beam, fish symbols from the

narrow beam (directly underneath your boat) are solid, and the returns from

the wide beam (out to the sides of your boat) are hollow.

The Sonar Page does not interpret the sonar return data.
Suspended targets appear as symbols. No background

information appears
Same as previous with the target depth shown.
Suspended targets appear as symbols. Background information

appears, making the distinction between fish and structure easier.
Same as previous with target depth shown.

• Scale—controls the appearance of the depth scale shown vertically along

the right side of the graph. You can configure the depth scale to appear in

one of four different ways: as an Overlay, in the Corners, Basic, or No

Scale.
