| The GMR 40 adds important
radar information to a system that already includes GPS,
sonar, and XM WX Satellite Weather data
components—making the Marine Network one of the most
comprehensive marine navigation systems on the market.
Impressive Performance
The GMR 40 (4kW 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
36 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 40 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 40 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 MARPA (Mini Automatic Radar Plotting Aid)
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 40 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 40) 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.
