Radar



The marine radar transmits microwave energy that has the potential to be harmful to humans and 

animals. Before beginning radar transmission, verify that the area around the radar is clear. The radar 

transmits a beam approximately 12° above and below a line extending horizontally from the center 

of the radar. Avoid looking directly at the radar, because the eyes are the most susceptible parts of 

the body.
When you connect your chartplotter to an optional Garmin marine radar such as a GMR

™

 404/406 or 

a GMR 18/24, you can view more information about your surroundings. The radar connects through 

the Garmin Marine Network and shares radar data with all networked chartplotters.
The GMR transmits a narrow beam of microwave energy as it rotates in a 360° pattern. When the 

transmitted energy contacts a target, some of that energy is reflected back to the radar.

1.  Turn on the network. 

The radar warms up and a countdown is provided to alert you when the radar is ready.
Note: As a safety feature, the radar enters standby mode after it warms up. This gives you an 

opportunity to verify that the area around the radar is clear before beginning radar transmission.

The zoom scale, also called the radar range, represents the distance from your position (the center) 

to the outermost ring. Each ring represents an even division of the zoom scale. For example, if the 

zoom scale is set at three miles, each ring represents one mile from the center out. 

For the GPSMAP 7000 series, from the Radar screen , touch the   and   buttons.
For the GPSMAP 6000 series, press the

The Radar screen has five standard operating modes. Each mode is available for use only with a 

Cruising mode—shows a full-screen image of the gathered radar information.
Harbor mode—intended for use in inland waters, this mode works best with short-range radar 

signals (2 nm or less).
