Pre-owned. Working condition. Instructions available online. Find your way through the wilderness with the GPSMAP 76CSx's high-sensitivity GPS receiver, which acquires satellite signals quickly and tracks your location in challenging conditions, such as heavy tree cover or deep canyons. You can use the built-in electronic compass to view bearing information even while you're standing still, and the barometric altimeter tracks changes in pressure to pinpoint your precise altitude. You even can use the altimeter to plot barometric or ambient pressure over time, which can help you keep an eye on changing weather conditions. The 76CSx's bright, color TFT display makes it easy to distinguish details on the screen in any kind of lighting. And, like the rest of the 76-series, 76CSx is water resistant (IPX7) and even floats in water.
