eTrex Vista C
The eTrex Vista® C is Garmin's exciting, new, pocket-sized handheld
that brings color, automatic routing, longer battery life, plus
more to our popular-selling eTrex
Vista. You won't miss a thing when you take this colorful,
lightweight, easy-to-use handheld out hiking, biking, boating or
even geocaching.
The eTrex Vista C along with the eTrex
Legend C are Garmin's smallest, least expensive products
to combine a color TFT display and advanced GPS routing capabilities
in a waterproof design.
Outdoor enthusiasts will love the latest improvements made to the eTrex Vista C :
Barometric altimeter provides extremely accurate elevation for hikers and climbers
Electronic compass so you can get a heading when standing still
256-color, sunlight-readable display makes it easy to distinguish map details and see where you're going
Automatic route generation, off-route recalculation, turn-by-turn directions with alert tones, and icon-driven menus for finding points of interest (when combined with Garmin's optional MapSource® CDs) navigate you safely to your destination
Longer battery life for more hours of outdoor enjoyment
Mini-USB port for fast, convenient download of map data from Garmin's entire library of optional MapSource CDs using a PC
Of course the eTrex Vista C still includes those popular features
that users have come to love and expect in the eTrex
product line, such as a compact, lightweight, waterproof design
and user-friendly interface. It is WAAS-enabled, and like all eTrex
units, the primary controls are oriented on the side of the unit,
so the user can conveniently operate it with one hand. Also, an
innovative rocker switch is located on the face of the unit that
enables the user to input data easily, scroll through menus, or
pan the map page.
