GPS E-TREX VISTA HCX
Enjoy Clear Reception
With its high-sensitivity, WAAS-enabled GPS receiver, eTrex Vista HCx locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons. The advantage is clear — whether you’re in deep woods or just near tall buildings and trees, you can count on Vista HCx to help you find your way when you need it the most.

Get Your Bearings
The Vista HCx has a built-in electronic compass that provides bearing information even while you're standing still, and its barometric altimeter tracks changes in pressure to pinpoint your precise altitude. You can even use the altimeter to plot barometric pressure over time, which can help you keep an eye on changing weather conditions.

Expand Your Memory
Adding maps is easier than ever with Vista HCx's microSD card slot. Conveniently plug in optional preloaded microSD cards with MapSource data for your land and sea excursions. Just insert a MapSource card with detailed street maps, and Vista HCx provides turn-by-turn directions to your destination. The card slot is located inside the waterproof battery compartment, so you don't have to worry about getting it wet.
