The Ultimate Beginner’s Guide to Handheld GPS: What Every Adventurer Must Know

Jul 04, 2025

Why Handheld GPS Is a Game-Changer (And Why Your Phone Isn’t Enough)

There’s something romantic about a map and compass. The old-school feel of navigating with the sun on your back and the wind in your face. But let’s be honest—when you're miles deep into the backcountry with shifting weather, fading daylight, and trails that barely exist, romance won’t get you home.

This is where a handheld GPS earns its place—not as a gadget, but as a lifeline.

Many beginners assume their smartphone will do the job. After all, there’s an app for everything, right? But ask any seasoned hiker, SAR professional, or solo trekker, and they’ll tell you: the deeper you go, the more fragile your phone becomes. Battery life drains fast in the cold. Signals vanish the moment you step into a canyon. And when the touchscreen freezes or gets soaked, that high-tech rectangle in your pocket becomes little more than dead weight.

Handheld GPS devices, on the other hand, are purpose-built for wilderness navigation. They’re rugged, weather-resistant, and designed to hold a signal even in dense forests or mountainous terrain. The battery lasts for days. And if you’ve preloaded your maps and waypoints, you can navigate blindfolded (not recommended, though).

But here's the truth: just buying a GPS doesn't make you wilderness-ready. A shocking number of people pack one for reassurance—only to realize too late they never learned how to actually use it.

The result? A growing list of avoidable rescues and search missions.

That’s why we created Ultimate GPS Mastery for Wilderness Adventures. Not just to show you which button does what—but to teach you how to think like a navigator. To move confidently through any terrain. To troubleshoot when the signal drops. To turn that device from a safety net into a superpower.

In this guide, we’re going to break down exactly what beginners need to know to get started—from choosing the right device, to setting it up properly, to making sense of coordinates, routes, and tracking features.

By the end of this series, you won’t just be carrying a GPS—you’ll actually know how to use it to stay safe, plan better, and go further.

Let’s get started.

Choosing the Right GPS for Your Adventures

So, you’re ready to invest in a handheld GPS. But one quick Google search later, you’re drowning in a sea of numbers, letters, and jargon: 65s, 67i, multi-GNSS, BirdsEye imagery… and somehow everything “works in rugged terrain.”

Don’t worry. You don’t need to be a tech wizard to make the right choice—you just need a clear sense of what kind of adventurer you are, and what your GPS needs to do for you.

1. Start with Your Purpose

Are you a weekend hiker? A backcountry skier? A remote area rescuer? Your mission should drive your decision.

Casual hikers and day trekkers may want a lightweight, budget-friendly model like the Garmin eTrex 22x—easy to carry, reliable signal, no fluff.
Intermediate to advanced explorers who go off-trail or into rugged zones will benefit from something like the Garmin GPSMAP 65s—multi-GNSS support, barometric altimeter, and a 3-axis compass for serious navigation.
Data-driven adventurers or SAR teams might want more: larger screens, satellite imagery, route planning tools, and features like Wi-Fi and smart notifications. The Garmin 67i is a beast—just be aware that inReach (satellite messaging) is a separate learning curve and not essential for everyone.

Don’t just buy the most expensive model thinking it’s automatically better. Choose the one that fits your style of adventure.

2. Know the Must-Have Features

Even entry-level GPS devices should include:

Preloaded maps (topographic or regional)
Waypoint marking and route tracking
Compass and altimeter functions
USB or Bluetooth connectivity for syncing with apps like Garmin Explorer

Optional but useful:

Color screens for better visibility in daylight
Expandable memory for extra map downloads
BirdsEye Satellite Imagery for high-detail terrain previews

Avoid overpaying for features you won’t use—like messaging capabilities or advanced sensors—unless your activities truly demand them.

3. Test for Fit and Feel

Just like boots, the best GPS is the one that fits you. Can you hold it and operate it with gloves on? Is the screen readable in direct sunlight? Does the menu system make sense to you? Try before you buy, if you can.

And always—always—check the battery setup. Some models take AAs, some have built-in rechargeables. Make sure you’re prepared to manage power on long trips.

4. Future-Proofing with Software Compatibility

Ensure your GPS is compatible with tools like Garmin Explorer App. This will allow you to plan routes on your computer, load them onto your device, and review tracks later. These tools turn your GPS from a navigator into a storytelling, training, and survival tool.

In the next section, we’ll show you how to set up your device the right way, including crucial steps many beginners skip—like satellite lock, customizing your map views, and making sure your settings match the terrain you’re actually in.

Setting Up for Success — Your First GPS Configuration

So, you've got your shiny new GPS device in hand. You unbox it, fire it up... and now what?

This is the part where many adventurers go wrong—they hit the trail with default settings, half-charged batteries, and no clue how their device is actually configured. But a few minutes of smart setup can mean the difference between getting lost and getting home.

Let’s walk through what you really need to do before your GPS ever sees the trail.

1. Power, Batteries, and First Boot

Check whether your device uses AA batteries or a rechargeable lithium-ion pack. Either way:

Install fresh or fully charged power before heading out.
Carry spares or a power bank, especially for multi-day trips.

When you power on for the first time, the device might take a few minutes to acquire satellite lock. This is normal. Do this outside, in a clear, open area—your backyard is perfect.

2. Language, Units, and Time Settings

Skip this and you'll end up trying to convert meters to feet mid-hike.

Set your language and units (kilometers vs. miles, meters vs. feet) based on what you're most comfortable with or what your topo maps use.
Use GPS-synced time to auto-adjust the clock. This helps align trip logs, timestamps, and daylight estimates.

Simple, but foundational.

3. Install Software Updates (Yes, Really)

Before hitting the trail, connect your GPS to a computer via USB and install:

Garmin Express (for updating device software and maps)
Optionally: Garmin Explore App (for planning and viewing routes)

Check for firmware updates. Garmin pushes bug fixes and new features regularly—some updates even improve satellite acquisition speed.

4. Acquire Your First Satellite Lock

Now go back outside. Stand still. Let the GPS acquire satellites fully (this can take a few minutes on first use). You’ll usually see signal strength bars or a sky-view chart.

Your GPS works using trilateration, communicating with at least 3 satellites—ideally 4 or more—to pinpoint your position on Earth.

Once your device locks in, you’re ready to test basic functions.

5. Set Your Profiles and Preferences

Modern Garmin devices allow for activity profiles—like Hiking, Mountaineering, or Geocaching. These profiles tailor how your data is tracked and displayed.

Customize:

Map orientation (north up vs. track up)
Track recording intervals
Data fields on map or trip screens (e.g., speed, altitude, ETA)

Dial these in now so you're not fumbling later in wind and rain.

6. Mark a Waypoint and Test Navigation

Before your first real outing:

Mark your current location as a waypoint.
Walk 50 meters away.
Navigate back using the GPS.

This test will build confidence, confirm your settings, and help you get familiar with directional indicators, distance tracking, and return routes.

A GPS is only as useful as the person holding it—and now you’re on the way to becoming that person. In the next section, we’ll dive into how to use your GPS like a pro on the trail, including following routes, recording tracks, and managing waypoints in real time.

Mastering On-Trail Navigation — Real Skills for Real Terrain

Now that your GPS is set up and talking to satellites, it’s time to put it to work in the field.

But make no mistake—this isn’t about blindly following a digital arrow. This is about using your GPS like an extension of your own instincts. The goal is to become a navigator, not just a follower.

Here’s how to make that leap.

1. Reading the Map Screen Like a Pro

Your GPS device shows more than just your location—it’s your personal command center.

Learn to:

Interpret topographic lines to understand elevation and terrain.
Identify waypoints (custom markers) and track logs (your breadcrumb trail).
Use the cursor and pan function to explore areas ahead and behind.

Most importantly, always know which direction is up on your screen. “Track up” rotates the map to follow your movement. “North up” keeps north fixed at the top. Choose what works best for your brain—and stick with it.

2. Following a Route

Routes are pre-planned sequences of waypoints or paths you create in BaseCamp or directly on the device.

To follow one:

Select the route from your saved data.
Hit “Go” or “Navigate”.
Let the GPS guide you point to point.

Watch the distance to next waypoint, ETA, and total distance remaining—these help pace your hike, plan breaks, and prevent overexertion.

Tip: If you miss a turn or go off route, many models will beep or alert you. You’re still in control, but now with an extra layer of safety.

3. Using the Trip Computer and Compass Screens

The Trip Computer gives real-time feedback:

Total distance
Average speed
Moving time vs. stopped time
Elevation gain

Customize this screen to show what matters most to you—whether that’s sunrise time, bearing, or current elevation.

The Compass Screen is perfect for bushwhacking or following a bearing. It points toward your next waypoint or destination. Use it in dense forest, low visibility, or when following a bearing across open country.

Bonus: Calibrate your compass before every trip—it takes 30 seconds and keeps your headings accurate.

4. Marking Waypoints in the Field

See something interesting? Need to mark a water source, camp spot, or emergency exit?

Press “Mark”, give it a name like “WATER1”, choose an icon (like a tent or flag), and save.

You can then:

Navigate directly to this point
Use it in a future route
Share it with others

Waypoints are your digital breadcrumbs. Use them often.

5. Tracking and Backtracking

Your GPS is always recording your movement in the background—this is your Track Log.

If things go wrong—fog rolls in, trail disappears—you can activate “TracBack” to follow your steps back to the starting point.

It’s your emergency escape plan. Reliable. Simple. Life-saving.

Final Word: Situational Awareness is Still King

Your GPS is powerful, but your eyes, ears, and brain still run the show.

Always:

Cross-reference your GPS with physical landmarks.
Trust, but verify—especially when trails split or signs are missing.
Pause periodically to orient yourself and confirm you're on the right path.

When you combine technology with human awareness, you become a force to be reckoned with in the wilderness.

This wraps up your crash course on using a GPS in the real world. You now understand setup, core functions, and field application—skills that thousands of hikers skip (and regret).
