Garmin eTrex 10 Handheld GPS Review

What the eTrex 10 actually is

This is the entry point to Garmin's long-running eTrex line, and it shows in both good and bad ways. You get a 2.2-inch monochrome screen, basic worldwide basemap, and a GPS receiver that locks on fast and holds a signal under tree cover. No color. No topo maps. No touchscreen. It's a coordinate machine that runs forever and shrugs off rain.

Price floats somewhere in the $100 to $140 range at Amazon, which puts it well under the color-screen eTrex 22x and the maps-and-glory eTrex 32x. You're paying for reliability and battery life, not features.

How it performs day to day

The headline number is battery life. Two AA batteries get you around 25 hours, and that's the real reason people buy this thing. A dead phone on a long hike is a navigation emergency. A dead eTrex just means you swap in two AAs you bought at a gas station. Owners back this up consistently.

Reception is the other strong point. It pulls in both GPS and GLONASS satellites, gets a fix quickly, and stays accurate in canyons and forest where phones drift. Mark a waypoint at the trailhead, follow the breadcrumb track back, done. The interface is dated and the buttons take some learning, but it's logical once you've poked at it for ten minutes.

Where it frustrates people is the screen. Monochrome and small means no real map detail, so you're navigating by waypoints, tracks, and coordinates rather than looking at a trail laid out in front of you. If you expect anything close to Google Maps, this will feel primitive.

The good and the annoying

Pros: genuinely rugged with an IPX7 waterproof rating, excellent battery life on cheap AAs, fast and accurate satellite lock, light enough to forget it's in your pack, and a price that doesn't sting. It also works as a paperweight-proof backup that you can leave in a glovebox or bug-out bag for years.

Cons: the basemap is barely a map, you can't add detailed topo maps like you can on the 22x and 32x, there's no wireless transfer or expandable memory, and the resistive interface feels like 2011 because the core design is roughly that old. The lack of an electronic compass and barometric altimeter won't matter to most, but power users will notice.

Who should buy it, who should skip it

Buy it if you want a dirt-simple, bombproof GPS as backup to your phone, if you geocache, or if you need accurate coordinates in the backcountry and don't care about pretty maps. It's also a smart choice for handing to a kid or a less tech-inclined hiking partner who just needs to not get lost.

Skip it if you want on-screen topo maps to follow visually. For maybe $40 to $80 more, the eTrex 22x adds a color screen and loadable topo maps, and that's the upgrade most hikers will actually appreciate. If you're a serious navigator, go straight to the 32x or a GPSMAP unit.

The verdict

The eTrex 10 is old, basic, and still completely worth it for the right buyer. It does one job, navigation that doesn't quit, and does it cheaply for days on a pair of AAs. Just go in knowing you're buying a coordinate tool, not a map experience. For most people who want maps, spend up for the 22x. For everyone who wants a reliable backup that outlasts every phone they own, this is the one.

Frequently asked questions

Does the Garmin eTrex 10 have topographic maps?

No. It comes with a basic worldwide basemap and can't load detailed topo maps. If you want loadable topo maps, step up to the eTrex 22x or 32x, which have color screens and expandable map support.

How long does the eTrex 10 battery last?

About 25 hours on two AA batteries. That long runtime on cheap, swappable batteries is the main reason people buy it as a backup for when a phone dies on the trail.

Is the eTrex 10 waterproof?

Yes, it carries an IPX7 rating, meaning it can handle rain and brief submersion in water up to a meter for 30 minutes. It's one of the more rugged GPS units at this price.
