Inland lake exploring or deep sea navigation is easier with the Garmin GPSMAP
172C. The rugged fixed-mount chartplotter can help you find where the fish are
or avoid underwater hazards.
Garmin's GPSMAP 172C is contained in a 4.9" H x 6.3" W x 3.7" D waterproof
case and can be exposed to the elements in any convenient location. The single-knob
tilt and swivel bracket works equally well as a surface or overhead mount. And
if the chosen location doesn't allow clear reception with an internal antenna,
an optional remote antenna can be used.
The display for the GPSMAP 172C is designed to be easy to view no matter
what the light conditions are. The 256-color LCD display measures 3.2" x 3.2"
(4.5" diagonal) and can be read in bright sunlight or at night with its
adjustable backlighting. The receiver runs off an external DC source of 10
to 35 volts or regular AC power with an optional adapter.
The Garmin GPSMAP 172C receiver has three features to assure maximum
positioning accuracy. Its 12 channels allows the simultaneous reception of up to 12
GPS satellites for maximum speed and accuracy in making location calculations.
It's Wide Area Augmentation System (WAAS) enabled for position accuracy of less
than 3 meters, 95% of the time. Or since it's Differential GPS(DGPS) ready, you can get
similar accuracy when used with an optional beacon DGPS receiver.
A world-wide marine basemap is built into the GPSMAP 172C to handle general
boating requirements. For greater details when fresh-water boating, Garmin offers
its MapSource, Recreational Lakes with Fishing Hot Spots. These maps
include fishing areas, marinas, boat ramps, and hazards for hundreds of lakes in
the U.S. and Canada. For ocean navigation, there's the MapSource, BlueChart
with depth contours, navaids, inter-tidal zones, wrecks and other points of
interest. Map data is stored on memory cards for quick and easy replacement.
If you want to increase the usefulness of the Garmin GPSMAP 172C, you can
add the GSD 20 Sounder Module. With this unit you can tell how hard the bottom is and
distinguish between the fish and thermoclines(uneven temperature water layers). The
depth and fish audible alerts can be set to give you instant notification when you're not
monitoring the display. And with the 172C's underwater waypoint ability and moving view
shown on its split screen, you can navigate to the choice fishing areas.
Garmin's 172C GPS receiver can store 3000 waypoints with added comments. Its
50 reversible routes let you quickly backtrack to your favorite spots. And the
tracklines can be color-coded for easy identification. With its selection of
optional maps and range of coordinate systems, you can navigate on the
water how and where you want.
