Using Radar

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 Garmin Marine Radar 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.

  WaRNiNG: 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 part of 

the body.

1.  Power 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 

microwave energy transmitted by the radar can potentially be harmful to humans and animals.

2.  From the Home screen, touch 

. The “Ready to Transmit” message appears.

3.  Complete one of the following actions:

Touch

Press and release the   

 key on the chartplotter. Do not hold the key, or you may shut 

down the chartplotter.

4.  Touch 

. A “Spinning Up” message appears for a few moments, then the radar 

begins painting an image.
