Best Overall Handheld GPS
Garmin GPSMAP 66st
The Garmin GPSMAP 66st is at the top of its class in terms of accuracy and reliability, earning it our top honors. It boasts a powerful quad-helix antenna and reliably connects to more satellite networks with greater accuracy than most other models. Even in less than ideal locations, like under thick tree cover or in a tight slot canyon, the GPSMAP 66st is able to maintain a satellite connection. When in the range of cell service, this unit can pair with your smartphone to overlay real-time weather data on your maps. Its 16GB of internal memory is more than double most other units and comes preloaded with topo maps for the US and Canada, as well as subscription-free access to Garmin's Bird's Eye Imagery.
As might be expected, all of this capability carries a hefty price tag. If you plan on a lot of expeditionary travel or need a highly accurate, handheld GPS for field research, the capabilities of the 66st are more than worth the investment. But for many who use a GPS unit for more casual recreation, this model will likely be overkill. Even additional features, like wirelessly linking to your phone, require a cumbersome setup process. Although this unit doesn't feature a touchscreen, we really appreciate the large buttons and their intuitive layout. The Garmin GPSMAP 66st is certainly a powerful unit, but one that is easy to use, even in the most extreme field conditions.

Best Bang for Your Buck
Garmin eTrex 32x
For those seeking a straightforward GPS that doesn't sacrifice much in terms of pure navigation performance, the Garmin eTrex 32x boxes well above its weight-class when compared directly with more advanced units. An excellent value that does not skimp in terms of reception and processing speed, this device even comes preloaded with Garmin's TopoActive basemap, which offers sufficient data for those who don't want to mess with having to find and upload individual maps. The available accuracy linking both GPS and GLONASS networks is only improved by the addition of a barometric altimeter and a 3-axis digital compass — two sensors often only reserved for much more expensive GPS units. Yet, this enhanced capability somehow doesn't affect its size and weight. Just as small and lightweight as other models in the eTrex line, this compact GPS can easily be stashed away in a pack or tossed into a pocket for a day hike.
There are still some limitations to this otherwise impressive handheld. Even though it has the ability for routable navigation, the relatively tiny screen is not reasonable for finding your way around a new city via car or even daily driving. It is also still very much a base-level GPS unit — although it supports Garmin's BirdsEye Satellite Imagery, it doesn't offer the same level of connectivity as more advanced units. Similarly, many used to modern user interfaces will find the joystick and T9-style keyboards clunky or tedious compared to the normalized convenience of a touchscreen. But as either a plug-and-play option for simple navigation or a durable, compact, and capable GPS for expeditions, the eTrex 32x presents an affordable option with more advanced capabilities.

Best for Messaging and Navigation
Garmin inReach Explorer+
The Garmin inReach Explorer+ is a standout, multifunctional device that keeps you reliably connected, even deep into the backcountry. With GPS navigation, SOS features, and satellite text messaging, the inReach Explorer+ is a standout as a highly capable device. We used it for a wide range of trips, from alpine climbing in Alaska to trekking in the Patagonian backcountry. Although it is primarily a messaging and SOS device, you can also use the inReach Explorer+ as a handheld GPS. It's easy to share your tracks and location via text messaging and social media. In addition to downloadable maps, the ability to preload waypoints and routes is helpful for planning long trips over complex terrain.
The Explorer+ has far fewer navigation features and a more limited interface than dedicated GPS models. Still, it works well for simple navigation and tracking. The Explorer+ is also an emergency personal locator beacon, and we caution against navigating with and draining the batteries of your lifeline. But, if you're okay relying on a single device and willing to carry a backup power source, this is the way to go. For those who want to go deep in the backcountry with a device that can be used for both messaging and navigation, the inReach Explorer+ is unparalleled. (We recommend the more compact inReach Mini as a personal locator and messager if you also have another means of navigating.)

Why You Should Trust Us
To test these devices, we put together an all-star crew of outdoor adventurers. Our head testers include: Chris Mcnamara, the founder of OutdoorGearLab, who at one point was calculated to have spent 3% of his life on El Capitan in Yosemite; Amber King, who when she's not teaching students as a science teacher, can be found covering long distances running, biking, or rafting in Colorado; Ethan Newmanwho is a climbing and canyoneering guide in Southwest Utah; and Aaron Rice, a ski patroller, avalanche instructor, and wilderness guide in New Mexico.
These lead testers — plus scores of friends and partners — took to testing these GPS units in real-world situations. From mountaineering in Alaska to ski touring in the San Juan Mountains of Colorado to winding through the canyon country of the Southwest, our testers used these GPS units in whiteouts, in slot canyons, and while temporarily stranded by flash floods to bring you insight into each device, pulled from real adventure epics. Our rigorous assessment process combined time in the field with objective testing, where we evaluated everything from reception accuracy to memory capability to size and weight. We compiled research, closely examined features and ease of use, and noted when some devices shine and when others completely failed. We utilized the expertise of our science-minded, adventure-obsessed testing crew so that we can provide the most accurate, objective reviews available on the internet.

Analysis and Test Results
We tested these handheld GPS devices over the course of years — hiking, skiing, mountaineering, canyoneering, kayaking, mountain biking, mapping plant populations, and more. We have marked and navigated to waypoints, compared map drawing speed, and tested the compasses of each unit against a trusty old, magnetic standby. We logged hundreds of miles on foot in Colorado, Washington, Utah, New Mexico, and Alaska. More than a dozen people — who range from GPS experts to complete novices — used these units to provide diverse feedback and bring you a review of some of the best handheld GPS units on the market.
Related: Buying Advice for Handheld GPSs
We rated our selection of handheld GPS units on six scoring metrics: reception, ease of use, display quality, speed, weight and size, and versatility. It is important to note that these are some of the best and most popular options available on the market; while scores may vary, the numbers are based on how well each device compared to the competition. Some of these qualities are undeniably more important than others, namely reception and ease of use. Without the accuracy of a satellite and the efficiency of a GPS, you might as well be using a map and compass.
GPS stands for Global Positioning System. Often it's used to refer to devices --- in this case, handheld — that can track and store timing and positional data. While this is a major misconception, they're often intended to be used in conjunction with a traditional map and compass. They are designed to be resistant to water, shock, and thermal stress, and any other harsh conditions you'd typically run into out in the wilderness. High-performing devices come with extras like cameras and topo maps and better antennas, more memory, altimeters, or internal electronic compasses. More baseline models tend to be lighter and simpler and can often boast better battery life. Before buying your next GPS, consider if you need one, what you intend to use it for, and how much you're willing to spend. It is important to consider your specific needs before purchasing, as these units often carry a hefty price tag.
The price of a handheld GPS tends to be tied directly to its performance, features, and amount of memory storage. The Garmin GPSMAP 66st has every feature you may ever need — with more memory than you possibly could ever need — but it's near the top of the price spectrum. Alternatively, our most price-point model, the Garmin eTrex 10, carries only the bare essentials for tracking.
Alternatively, most people these days have smartphones with GPS capabilities and inexpensive apps that offer topo maps and tracking functions. Although this combination isn't as accurate as a real deal GPS unit, they are good enough for many folks.
So, who needs a handheld GPS? Those who love to hike off the main trail, serial bushwhackers, backcountry skiers, and climbers who frequently descend on unfamiliar and poorly marked trails. Adventurers of this breed will benefit the most from a GPS, which can pinpoint their exact location and allow them to re-orient themselves on a map and find the way home. A GPS is also helpful in bad weather conditions (heavy rain, snow, or fog), hiking on a dark cloudy, or moonless night, or when traveling over snow-covered terrain when the ordinary trail is buried, and the tracks of those who came before you may be unreliable (they might be just as lost as you — believe us, we've been there).
No. We strongly recommend carrying a map and compass when in unfamiliar terrain. Maps don't run out of batteries or break if accidentally dropped off a cliff. They serve as a fail-safe backup to any electronic device.
The reception of your smartphone simply may not prove reliable in the backcountry. Smartphones rely on the combination of a cheap GPS device and triangulation between cell towers (and even WiFi) to dial in your location. Yet, many of the best hikes are in the mountains, deserts, or pristine backcountry areas where there is no reliable cell support, and so your smartphone's GPS sensors might not cut the mustard.
Still, in situations where they do work, smartphone apps like Gaia, Avenza, or Topo Maps are great and can quickly identify your location on established trails before resuming map navigation. Smartphone GPS works best if you are in a region where cell signal is available, but it may become unreliable when you get into the backcountry. Just don't forget to download maps before leaving cell or WiFi signals behind. A touchscreen model with automatic routing — like the Garmin Montana 700 — is a great option that can double as both a driving GPS and for off-road travel.
In contrast to smartphones, handheld GPS units are burlier, with much better GPS satellite reception, more powerful navigation features, and supply better battery life in cold climates. A few questions will help narrow your search for the perfect handheld. After you figure that out, you can start thinking about all the bells and whistles — i.e., features.
Most modern GPS units are incredibly accurate and can pinpoint the device's location to a resolution of 10-meters. According to Garmin, units that use the Wide Area Augmentation System (WAAS) can be accurate to 3-meters or less. All the devices we tested use WAAS. To get even more accuracy, you can buy a differential beacon receiver and antenna to utilize a distance correcting Differential GPS (DGPS). Modern smartphones, in contrast, offer GPS accuracy of around 4.9 meters, according to GPS.gov.
Tall buildings, canyons, and trees can interrupt satellite signals, slowing them down and reducing your device's accuracy. Clouds and weather, however, shouldn't affect reception. To get the best signal with the satellites, it's best to carry your device outside your pack or in a light waterproof layer.
We found that the highest performing — but unfortunately, also often the most expensive — models tend to achieve the best satellite reception. Units like the GPSMAP 66st include quad-helix antennae, which are quite sensitive even in dense cover. Electronic compasses — as opposed to a mechanical, differential compass — also improve accuracy when on the move and are included in expensive units like the Montana 700, but surprisingly in more affordable units like the eTrex 32x. Even without these additions, however, all of the Garmin units we tested provided quality reception. All of the units we tested carry receivers that accept both GPS and GLONASS satellites, so even price-point models — like the eTrex 10 — offer nearly top-notch reception in almost every situation.
Ease of Use
GPS units usually come with a very rudimentary basic base map that distinguishes roads but not much else. As we mentioned above, you can buy a GPS unit preloaded with topo maps or buy them separately after the fact. You can also download maps and satellite imagery for free and transfer them to your unit. The United States Geological Survey offers a wealth of free spatial data. Most states in the US also have a website that distributes spatial data. If you want the best maps, often for free, spend some time tinkering with this data. If you want more convenient, straightforward map access, you can get them for around a hundred bucks from your GPS manufacturer.
The US National Agricultural Imagery Program (NAIP) shoots high-quality, free satellite imagery (aerial photos stitched together) for the entire continental United States. You can also buy satellite imagery. Often this is unnecessary because you can plan your routes in Google Earth and then send files to your mapping software and device. Satellite imagery is hard to see on most GPS units and is rarely necessary for the backcountry. Like the GPSMAP 66st, some units come with a free subscription to Garmin's database of Birdseye satellite imagery that can be downloaded on WiFi.
Each GPS manufacture offers software designed to organize, analyze, and display the waypoints and tracks you collect with your GPS. Garmin's Basecamp is our favorite. It's simple, intuitive, cross-platform, and provides everything a basic GPS user needs. For example, you can easily see waypoints or tracks in Google Earth. It is also an essential feature on really basic models like the eTrex 10, which due to its lack of mapping capability, would otherwise be rendered useless.
Do you want a compact version like an eTrex 32x, or are you willing to haul extra weight — like the Montana 700 — for perks like a larger screen? Is a big GPS screen more important because you would like to be able to quickly see information at a glance while driving? Or are you willing to squint for a more portable unit? Since all of the units in this review are handheld, none are huge — but there is definitely a difference in screen size and display quality between them.
The Montana 700, with a 5-inch diagonal screen, offers the largest screen and also the highest quality resolution. Its smartphone-like touchscreen makes navigation easy, particularly in a car. The Oregon 750t and GPSMAP 66st both have a 3.75 square-inch screen — nearly half the size — but more than adequate for a handheld unit. However, the major difference is that the Oregon 750t is a touchscreen, while the GPSMAP 66st is button-controlled.
So then, buttons or touchscreen? Touchscreens respond faster than button units, but they also consume more battery life, can freeze up in cold conditions, and don't work well with thick gloves. Most touchscreen GPS units we tested are also years behind most smartphones. Buttoned units work with thick gloves, their batteries last longer, and they are more reliable in extreme temperatures. But they're slower, and it takes longer to type in waypoints. It comes down to preference. Do you prefer a unit that feels modern and operates quickly? Or do you value reliability above all else?
GPS units work by communicating with satellites orbiting the earth designed to read and triangulate signals sent from the unit. In the United States, the Department of Defense manages the GPS network, a series of 33 satellites that transmit both positional and timing data. When a GPS unit contacts at least four satellites, it can pinpoint your position with a decent degree of accuracy, although terrain and conditions can affect this. Some of the units we tested are also able to interface with other countries' satellites, including the 26 satellites of the Russian GLONASS system or 26 more from the European Union's Galileo network. The more satellites, the faster and more accurately you can identify your position.
All handhelds also use the WAAS (Wide Area Augmentation System) to increase accuracy. Satellites send signals to WAAS master stations on the ground. This message is then relayed to compatible receivers (like GPS units) to provide a much more accurate location estimate. GPS units that use GLONASS, GPS, Galileo, and WAAS will offer the best reception.
The fastest — and most accurate — unit we tested was the Garmin GPSMAP 66st, as that is the only unit that was able to access all three of those satellite networks and improve its signal with WAAS. However, many of the other units we tested were able to achieve accuracy within 10 feet very quickly. Although the Montana 700 and inReach Explorer+ were nearly as speedy as the 66st, even basic units like the eTrex 32x impressed us with how quickly they were able to lock onto a signal after powering on.
Weight and Size
We tested handheld GPS units. These units are very capable, able to mark waypoints, track your route, make notes, geocache, pull up altitude profiles, and often much more. But they are also small enough to wear around your neck or stash in your backpack. The Garmin inReach Explorer+, despite its two-way communication capability, is also very portable. But the more features you add to a portable GPS unit, the larger and heavier they become. Handheld devices are popular for backcountry navigation, particularly because they are so portable.
However, not all units are created equally regarding portability, so it is important to consider if you want to carry a GPS in your pocket or will most likely only take one of these devices when you are also carrying a backpack. The Montana 700 is by far the largest and heaviest unit in our review but still weighs only 14 ounces and is only slightly bulkier than a modern smartphone. The eTrex line falls at the other end of the spectrum — both the eTrex 10 and more capable eTrex 32x are small enough to fit into a pant's pocket.
Just as a point of comparison, there are also a variety of GPS Watches that can log backcountry travel information. These are popular among trail runners, mountain guides, hikers, and backpackers. They are a great alternative to handheld units if you're looking to go light but have a much shorter battery life, a significantly smaller display, and may not offer the same capabilities as the handheld units featured here.
Most of the units featured in this review are surprisingly versatile; sporting functions well outside the realm of navigation, ranging from flashlight to calculator to texting. We won't dive too deeply into each function of each model we tested but rather will discuss a few important ones.
You don't need that many waypoints to get you through a trip, even a pretty long one. Even 500 waypoints — the minimum number on the units we tested, on the inReach Explorer+ — is likely more than most people would need at one time. They're also very easy to save on a computer and then delete after you're back home. If, however, you plan on holding on to waypoints from multiple trips, conducting involved science surveys, or embarking on a mapping mission — you might want to aim high. The eTrex Touch 35 offers the best capability in the smallest package. But for many of these units, you can also boost your unit's memory with a microSD card; only the inReach Explorer+ and eTrex 10 don't support extra external memory.
Geocaching is a relatively new outdoor activity, essentially using a GPS unit or GPS software for a scavenger hunt of sorts, looking for hidden treasures all over the world. Most GPS units are set up for this somehow, and some of the ones we tested have preloaded geocaches so you can unpack and play. A huge draw for the geocaching crowd is that a modern GPS unit — with text display — allows them to go paperless. For easy entry to this worldwide phenomenon, the Garmin eTrex 10, thanks to its accuracy balanced with affordability.
Electronic vs. Differential Compass
The cut-off point between basic units and more sophisticated ones is usually an electronic compass. This allows a unit to display your heading while held in place. In contrast, you have to be moving for a differential compass to work properly. For some, this is a great advantage — say during a whiteout next to a cliff edge. Many mountain guides prefer an electronic compass because it makes navigating faster and easier. Only the eTrex 10 doesn't offer an electronic compass.
Another feature that separates high-performing devices from base models is a barometric altimeter, which uses a small sensor to detect air pressure and calculate altitude instead of relying on positional data alone. Barometric altimeters also allow you to track weather patterns and trends, which can be really useful in the mountains when knowledge of a coming storm is crucial. Only the baseline-level eTrex 10 doesn't come with a barometric altimeter.
A camera, microphone, and voice recorder can be nice add-ons to fully document adventures or field data. You can use these media options to mark a waypoint instead of typing one. We loved this option when looking back at our past adventures. Photos also help keep you on the trail when following a track. This is especially helpful for outdoor guides or scientific surveys. While many options boast a photo viewer, the Oregon 750t is the only GPS in our review to include a camera. But extras like that also come at the price of the added size.
Wireless Capability and Smart Notifications
Another great feature is smart notifications. You can sync your smartphone to your GPS and receive text messages or social media updates on the unit. High-end units like the GPSMAP 66st sport this high level of technicality, but it does take some time and know-how to set up. If you don't want to take your phone out of the backpack while staying connected, this may be an option for you.
GPS units are great when you need them, but they don't come cheap. A smartphone can probably get you by until you're heading out on a multi-day backcountry trip guided by a map and compass, scouting multiple complicated routes, or conducting long field surveys. If you get to that point, you might as well invest because there's no substitute for a dedicated, accurate handheld GPS unit.
