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 

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. 

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.
