Using Radar

Cruising mode is the standard radar operation. If you switch from Sentry mode to Cruising mode, 

the antenna will go into full-time transmission and will disable any guard zones. You can place the 

radar in Cruising mode by selecting 

 > 

.

Use the Cruising screen to view a full-screen image of the gathered radar information. Your position 

is in the center of the screen, and the rings provide distance measurements.

The zoom scale 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 

kilometers, each ring represents one kilometer from the center out. Use the 

 (+/-) keys 

(GPSMAP 4000 series) or the   and   keys (GPSMAP 5000 series) to adjust the zoom scale.

Sentry mode allows you to put the radar antenna into timed-transmit mode, in which you can 

configure a transmit/standby cycle. You can also enable a guard zone in Sentry mode, which 

identifies a safe zone around your boat. An alarm sounds when a radar object enters this zone. You 

can place the radar in Sentry mode by selecting 

 >

  NOtE: When Sentry mode is enabled, all MARPA targets are cancelled, and you cannot acquire 

MARPA targets until you exit Sentry mode.
