If you want a mapping GPS receiver without frills, the Magellan SporTrak Map
may be just what you're looking for. It has all the accuracy and reliability you need for any
outdoor navigation activity. And its ease of operation makes it right for even the first-time
The case of the Magellan SporTrak Map measures just 2.2" W x 5.6" H x 1.2" D and
yet contains a 12-channel GPS receiver capable of position accuracy to within three
meters. Regular accuracy for the receiver is within seven meters but by using the
Wide Area Augmentation System (WAAS), it reduces errors by over half. Similar accuracy
can be achieved using Differential GPS (DGPS), since the receiver is also DGPS ready.
However DGPS does require you also have a beacon receiver, which makes it more
cumbersome than WAAS.
Although it doesn't add anything to the 6.1 ounce weight of the SporTrak Map, the basemap
certainly contributes to its value. The receiver has 2 MB of North American map data
built in. It's like a glove compartment full of interstate road maps showing the
major roads, waterways, and cities. It also has 6 MB of memory for storing
additional maps you may download. These could be city street maps, marine charts, or
topographic maps for countryside explorations.
If you can read and have a thumb (or finger), you can use the Magellan SporTrak
Map. The large center key is a directional control like a computer's mouse. And
with it, you select from a menu one of the seven main information displays. The
most often used display is the Map Screen. This shows your location on the map
along with two customizable data fields. These fields can display various trip
information of your choice, such as speed, direction, or the estimated time to
your destination. With pan and zoom controls you can view whatever area and detail
you want. Other screens include your direction, as shown by a compass image or
with text, your speed on a speedometer's image or the text numbers, position
information, and local GPS satellite status. Except for the satellite screen,
each screen includes customizable data fields.
Data fields aren't the only thing you can customize with the SporTrak Map.
Besides longitude and latitude, there are 11 other map coordinate systems you
can choose from as well as 76 map datum. If English isn't your favorite language, you have
eight other choices for the text displays. And the several programmable
alarms, let you choose to have a visual alert or include a tone sounded at the same time.
This is particularly helpful for off-course notification or arriving at a certain
point. And if you ever forget what your options are, there's a built-in help
system to guide you through that feature.
With its two AA batteries, you can get up to 14 hours of continuous use. And
the high-contrast grayscale screen of the Magellan SporTrak Map makes sure you'll
have clear displays every minute. The contrast is adjustable for the 1.4" W x 2.2" H
display. And with backlighting for both the screen and keypad, navigation is
possible night or day. This receiver is made for use on land and water, since its
rubber-cushioned case protects it against impacts and if dropped in the water, it will float.
