Garmin GMR Fantom™ 256 Radar
THE POWER TO SEE MORE
GMR Fantom™ 256 is the most powerful 6’ consumer solid-state radar.
The GMR Fantom™ 256, our most powerful 6’ solid-state radars, feature 250 W of
power. They use MotionScope™ technology to detect and highlight moving targets
in different colors, which helps you avoid potential collisions, find flocks of
birds and track weather. New MARPA Automatic Acquisition allows for triggering
and tracking with no user prompting on all returns, boundary zones, guard zones
or MotionScope. Scan-to-scan averaging, a new feature, helps aid in reduction of
sea clutter and interference. Its Pulse Compression technology provides
high-resolution imaging and maximizes energy to help you detect and identify
targets. Auto Bird Gain helps you identify flocks of birds on the water. The GMR
Fantom 256 radar have a detection range of 20’ to 96 nautical miles.

MOTIONSCOPE TECHNOLOGY
MotionScope technology detects and highlights moving targets in
different colors to help avoid collisions, find flocks of birds and track
weather from 20’ to 96 nautical miles.
AUTOMATIC ACQUISITION
New mini-automatic radar plotting aid (MARPA) automatic acquisition allows
for triggering and tracking of up to 30 targets with no user prompting on
all returns, boundary zones, guard zones or MotionScope.
CLEAR THE WAY
Scan-to-scan averaging aids in reduction of sea clutter and interference, so
you have a clear view of what’s out there.
AUTO BIRD GAIN
Where there are birds on the water’s surface, there are fish below it. Auto
Bird Gain helps you locate flocks of birds at the water’s surface.
PULSE COMPRESSION
This feature provides high-resolution imaging while maximizing energy to
enhance target detection and identification.
ECHO TRAILS
True Echo Trails feature displays a fading trail to help you quickly and
easily identify moving targets while accounting for the movement of your own
boat.
RADAR OVERLAY
Overlay radar on your chart screen as single display or split screen with
independent range settings.
DYNAMIC SEA FILTER
Dynamic Sea Filter automatically adjusts gain to calm, medium and rough sea
conditions.
