| The GARMIN GPS 12 Personal Navigator: an affordable 12 parallel
channel handheld for outdoor adventurers who want a basic, hard-working
12-channel GPS, but who don't want to spend a bundle. Based on the
popular GPS 12XL, the GPS 12 offers outdoor enthusiasts an entry-level
way to gain the power and performance of a 12-channel receiver with
fast satellite acquisition in the toughest conditions—even
in heavy tree cover.
The GPS 12's rugged, waterproof case features military-tough
construction, and its rocker keypad design provides true one-hand
operation that keeps you on the move—day or night, rain or
shine. It also features 500 available waypoints and 1024 track
log points, nine proximity waypoints to mark and steer clear of
dangerous areas, and GARMIN's innovative TracBack™ function—a
feature that turns your track log into an instant breadcrumb trail
and allows you to reverse your route in order to quickly navigate
back home. As an added bonus, the GPS 12 also boasts a position
averaging feature which diminishes the effects of Selective Availability
(SA) upon position error and displays a value that reflects the
estimated accuracy of the averaged position.
Include a host of advanced navigation features like enhanced
moving map graphics, average and maximum speed data, and trip
timers, and you have all the things that make the GPS 12 a purebred
GARMIN—innovation, performance, and value
