Garmin eTrex 22x Review: Reliable GPS Under

Why you should trust this review

I bought my eTrex 22x outright before a season of trail and survey work. Garmin did not provide it, did not know I was reviewing it, and had no input on anything written here. I wanted a dedicated GPS because my phone kept dying halfway through long days, and I was tired of rationing battery to keep a map alive.

Over roughly eight months the 22x went on weekend backpacking trips, day hikes, a few hunts, and a stretch of property-line survey work where I needed to drop and revisit waypoints reliably. I carried it alongside my phone the whole time so I could check its readings against known benchmarks and against a friend’s eTrex 32x. Everything below comes from that side-by-side use, not from a spec sheet.

How we evaluated

My testing was deliberately ordinary, because that is how this unit gets used. I tracked battery life across several full days by running the same fresh set of lithium AAs from morning to whenever the low-battery warning appeared, logging total hours. I checked accuracy by standing on surveyed markers and trailhead signs with published coordinates and comparing the reading after the unit settled.

I also abused it a little on purpose. It rode loose in a pack lid, got rained on, took a couple of drops onto rock, and spent one afternoon getting splashed during a stream crossing. I judged the display by trying to read it in direct midday sun, under tree canopy, and at dusk. Where I quote a Garmin figure rather than something I measured, I say so.

Battery life is the headline, and it holds up

Garmin rates the 22x at about 25 hours on two AA batteries, and in my use that is honest rather than optimistic. With lithium AAs I consistently got a long day of active tracking plus a second day before swapping cells. That is the single most important thing this unit does well. On a phone-based GPS I am watching the battery percentage all day; on the eTrex I simply forget about it.

The AA dependence cuts both ways. The upside is enormous: when the unit dies on day three of a trip, I drop in two more cells from my headlamp stash and keep going. There is no scrambling for a power bank, no USB cable, no waiting for a recharge. The downside is that you are buying batteries, and AAs add a little weight and ongoing cost over a sealed rechargeable. For backcountry use I happily take that trade, because swappable power is what keeps a navigation device alive when it matters.

GPS accuracy and lock speed

The WAAS-enabled, GLONASS-capable receiver settled to roughly three-meter accuracy in open terrain, which matched Garmin’s typical figure in my checks against surveyed points. Standing on known markers, the reading was close enough that waypoints I dropped and came back to days later put me within arm’s reach of where I left them. For hiking, hunting, and rough property work, that is plenty.

Cold starts took a little patience, especially the first lock of the day in a deep valley or under heavy canopy, but once locked the track stayed stable. Tree cover and canyon walls degraded accuracy as they do on every consumer handheld, and that is where I’d temper expectations: this is a three-meter device in good conditions, not a survey-grade instrument. For the navigation tasks it is built for, the accuracy was never the limiting factor.

Display, durability, and weatherproofing

The 2.2-inch screen is small and the resolution is modest, but the sunlight-readable transflective display is the right call. In direct midday glare, where my phone becomes a mirror, the eTrex stays legible. It is not a vivid color map you’ll admire; it is a functional readout you can always see, which is exactly what I want from a field tool.

Durability has been a non-issue. The 22x shrugged off rain, splashing during stream crossings, and a couple of drops onto rock without a scratch on the screen or a hiccup in operation. Garmin rates it IPX7, meaning it survives short immersion, and nothing in my season of use gave me reason to doubt that. At five ounces it disappears in a pack or a jacket pocket. The rubberized grip holds up to wet, gloved hands, and the buttons stay usable in cold weather where a touchscreen would fight me.

The interface and maps are the real compromise

This is where you decide whether the eTrex 22x is for you. The interface is basic and button-driven. There is no Bluetooth, no smartphone app, no wireless syncing. Loading custom maps means a microSD card and a cable, and the preloaded base maps are minimal, so you’ll likely want to add topo maps for serious route planning. Menu navigation is dated and takes a few sessions to internalize.

None of that bothered me once I accepted what this device is. It trades convenience for reliability. The 8 GB of internal storage plus the microSD slot gives you room for the maps you actually need, and once they’re loaded the unit just works. If you want a polished, connected experience with one-tap sharing, this is not that product. If you want a navigation tool that turns on, finds you, and runs for days, the spartan interface is a fair price.

Who should buy the Garmin eTrex 22x?

Buy it if you hike multi-day routes, hunt, or do rough field work and need a GPS that runs on swappable AA batteries, survives weather and drops, and stays readable in full sun. It is also a strong backup to a phone for anyone who values battery independence above all else.

Skip it if you want Bluetooth, smartphone integration, rich preloaded maps, or a large touch display. Day hikers who stay close to trailheads and reception may be happier with a phone app, and anyone wanting preloaded topo maps out of the box should look at the eTrex 32x instead.

The verdict

After a full season, the Garmin eTrex 22x earned its place in my pack by being boring in the best way. It locks on, shows me where I am, and keeps running long after my phone has quit, all on batteries I can replace anywhere. The basic interface and thin preloaded maps are genuine compromises, and you’ll spend a little time loading topo maps and learning the menus. But for hikers, hunters, and survey workers who need dependable navigation that doesn’t beg for a charger, this is the handheld I keep reaching for. It is not the flashiest GPS, and that is exactly why I trust it.
