| The GMR 20
adds important radar information to a system that already includes GPS,
sonar, and XM WX Satellite Weather data components—making our
Marine Network one
of the most comprehensive marine navigation systems on the market.
Impressive Performance
The GMR 20 (2kW radome) features a narrow 3.6-degree
horizontal and 25-degree vertical beamwidth, which delivers accurate
target acquisition and better penetration through rain and fog. It has a
range of 24 nautical miles (nm). For fast and efficient presentation of
radar signatures, raw data is processed within the radome and presented
on Garmin’s
GPSMAP®
3006C and
GPSMAP 3010C chartplotter/multifunction displays (MFDs).
Ease of Use
The GMR 20 features automatic and manual sensitivity
and tuning controls, including gain, sea clutter, and rain clutter—which
allows boaters to spend less time tuning the unit and more time
navigating. The unit also boasts selectable interference rejection,
which mitigates the effect of nearby radar transmissions.
Advanced technology
Once the GMR 20 is interfaced with a GPSMAP 3006/3010
MFD, it is possible to overlay radar images on the charting to help
reconcile radar signatures with known objects. Users can view "radar
only" or split the display for multiple views of radar and charting.
To aid in collision avoidance, the unit also offers
Mini Automatic Radar Plotting Aid (MARPA) capability, which allows
boaters to track the bearing, course, speed and predicted closest
approach (by both time and distance) of up to 10 targets. MARPA
functionality requires GPSMAP 3006/3010 MFDs and an optional heading
sensor.*
Marine Networking
The GMR 20 communicates with the Garmin Marine Network
through a waterproof 100-megabit plug-and-play proprietary network—which
affords users the ability to expand their boat’s system as needed.
Boaters can connect a GPS antenna and one remote network sensor (like
the GMR 20) directly to the MFD—or with the addition of the GMS™ 10
Network Port Expander, users can connect multiple MFDs and network
sensors to the same network.
The GMR 20: Giving boaters more confidence and
enjoyment on the water.

dealer or installer for details. |
