Especially in inclement weather, longer-range radar signals 

can increase the clutter on the Radar screen and make it 

more difficult to view information about shorter-range targets. 

In rain, shorter-range radar signals can enable you to view 

information about nearby objects more effectively, if the rain 

clutter setting is configured optimally.

• Select the shortest effective range, given your reason for 

using radar and the present environmental conditions.

MotionScope

 Doppler Radar Technology

The GMR Fantom radar uses the Doppler effect to detect and 

highlight moving targets to help you avoid potential collisions, 

find flocks of birds, and track weather formations. The Doppler 

effect is the frequency shift in the radar echo due to the relative 

motion of the target. This allows for instant detection of any 

targets moving toward or away from the radar.
The MotionScope feature highlights the moving targets on the 

radar display so you can navigate around other boats or severe 

weather, or toward fishing spots where birds are feeding at the 

surface.
The moving targets are color-coded so you can tell at a glance 

which targets are heading your way and which are heading 

away from you. On most color schemes, green indicates the 

target is moving away from you and red indicates the target is 

moving toward you.

Enabling a Guard Zone

You can enable a guard zone to alert you when anything comes 

within a specified area around your boat.

NOTE: 

This feature is not available in dual radar modes.

Defining a Circular Guard Zone

Before you can define the boundaries of the guard zone, you 

must enable a guard zone (

Enabling a Guard Zone

, page 29

).

You can define a circular guard zone that completely surrounds 

your boat.

Select the location of the inner guard zone circle to define the 

width of the guard zone.

Defining a Partial Guard Zone

Before you can define the boundaries of the guard zone, you 

must enable a guard zone (

Enabling a Guard Zone

, page 29

).

You can define the boundaries of a guard zone that does not 

completely surround your boat.

again when needed.

MARPA

Mini-automatic radar plotting aid (MARPA) enables you to 

identify and track targets and is primarily used for collision 

avoidance. To use MARPA, you assign a MARPA tag to a 

target. The radar system automatically tracks the tagged object 

and provides you with information about the object, including the 

range, bearing, speed, GPS heading, nearest approach, and 

time to nearest approach. MARPA indicates the status of each 

tagged object (acquiring, lost, tracking, or dangerous), and the 

chartplotter can sound a collision alarm if the object enters your 

safe zone.

MARPA Targeting Symbols

Acquiring a target. Concentric, dashed green rings radiate from 
the target while the radar is locking onto it.
Target has been acquired. A solid green ring indicates the 
location of a target that the radar has locked onto. A dashed 
green line attached to the circle indicates the projected course 
over ground or the GPS heading of the target.
Dangerous target is in range. A red ring flashes from the target 
while an alarm sounds and a message banner appears. After 
the alarm has been acknowledged, a solid red dot with a dashed 
red line attached to it indicates the location and the projected 
course over ground or the GPS heading of the target. If the safe-
zone collision alarm has been set to Off, the target flashes, but 
the audible alarm does not sound and the alarm banner does 
not appear.
Target has been lost. A solid green ring with an X through it 
indicates that the radar could not lock onto the target.
Closest point of approach and time to closest point of approach 
to a dangerous target.

Assigning a MARPA Tag to an Object

Before you can use MARPA, you must have a heading sensor 

connected and an active GPS signal. The heading sensor must 

provide the NMEA 2000 parameter group number (PGN) 

127250 or the NMEA 0183 HDM or HDG output sentence.
