If your idea of a trip is one that starts when the road ends, you'll like the Magellan
SporTrak Topo GPS receiver. It comes with an extensive built-in nationwide
topographic map database. Combined with the handheld's small size, light
weight, and rugged design, you'll find it can be the right navigation tool to guide you anywhere.
Packed into its 2.2" W x 5.6" H x 1.2" D case, the Magellan SporTrak Topo
has 8 MB of general map features and 100 MB of topographic map detail. This basemap
covers 80% of Alaska and 100% of the other 49 states. Topographic contouring and
elevation is shown, along with major roads, cities, waterways, and coastlines.
Included with the receiver is a CD of Magellan's MapSend Topo 3-D topographic
maps, to be used if you want enhanced details. The CD has much more information on lakes
and rivers, major and minor roads, and outdoor recreation points of interest.
The data can be downloaded from a PC using the included interface cable. If you should
need city street maps or some area not already covered, there's 16 MB of
memory for additional map data.
Position accuracy for the SporTrak Topo is within seven meters horizontally
and ten meters in elevation. To achieve greater accuracy, the receiver can use
the Wide Area Augmentation System (WAAS), the European Geostationary
Navigation Overlay System (EGNOS), and Differential GPS (DGPS). WAAS and EGNOS
require no other equipment and can reduce position errors to less than three
Even for first-time users, the operation of the Magellan SporTrak Topo is
simple. With its menu system and directional keypad, it's easy to move
through the nine navigation screens. There are screens which display their
information with images and others with text only. And most screens have
data fields which display your choice of trip information. Additionally, you
have a choice of nine languages for the text. And since there's a built-in
help system, guidance for screen functions is always available.
Viewing the navigation screens on the SporTrak Topo is never a problem with its
high-contrast grayscale LCD. The 1.4" W x 2.2" H display has adjustable contrast
and backlighting for reading under any light conditions. The keypad is also backlit
and to help save battery power, there's a shut-off timer. It can be set to turn off
the backlight if a key hasn't been pressed for a certain interval. Tapping any key
will turn the backlight back on.
Additional features of the Magellan SporTrak Topo include 12 map coordinate
systems and 76 datums, storage for 20 routes and 2,000 track points, automatic
conversion of your path to a route, optional tones to alert you if you're off
course or you've reached a certain point, sunrise and set times for any area and date,
and a best-times hunting and fishing database. There's even a simulation mode to let you
practice your navigation skills without having to go anywhere. The receiver uses
two AA batteries which can supply up to 14 hours of continuous use. And all this
is in a 6.1 ounce package that floats.
