GPS Units

Q: What’s the difference between a GPS unit and a smartphone GPS app?

A GPS unit is purpose-built for navigation in remote areas, providing more accurate positioning, better battery life, and rugged durability compared to smartphones.

Q: Which GPS is best for hiking?

The Garmin eTrex and GPSMAP series are the best handheld GPS units for hiking, offering reliable satellite tracking and preloaded topographic maps.

Q: Can I use a GPS unit without cell service?

Yes. GPS units use satellite data, not cellular signals, allowing full navigation and mapping capabilities even in no-service zones.

Q: Do GPS units show elevation data?

Yes. Many GPS models include integrated barometric altimeters to display real-time elevation and track ascent or descent progress.

Pro Tip

Before heading out, always download offline maps to your GPS unit or smartphone for use in areas without service. Pair your GPS with an altimeter or compass for added navigation accuracy in rugged terrain.

Understanding GPS Navigation for the Outdoors

GPS units use satellite signals to pinpoint your position anywhere on Earth, even off-grid. Many models combine topographic mapping with altimeter and barometer sensors to give you elevation, pressure, and weather information in real time.

Modern devices include features like trackback navigation, customizable routes, Bluetooth syncing, and global SOS functionality — essential tools for long-distance treks or overland travel.
