Field GPS devices collect the spatial data that ends up in GIS systems — survey points, asset locations, ecological transects, trail routes, boundary waypoints. Choosing the right device depends on the accuracy you need, the environment you work in, and how the data flows into your GIS workflow.
All the devices on this list export GPX format — the universal GPS exchange standard supported by every GIS application. Once you have a GPX file, you can convert it to Shapefile, GeoJSON, KML, or GeoPackage for use in QGIS, ArcGIS, or any GIS pipeline.
GPS accuracy explained
| Accuracy tier | Typical device | Use cases |
|---|---|---|
| 3–5 m (consumer) | Garmin eTrex, smartphone | Hiking, trails, rough asset mapping |
| 1–3 m (sub-metre) | Bad Elf Pro+, Eos Arrow 100 | Ecological surveys, utility assets, field GIS |
| 0.3–1 m (professional) | Trimble R1, Eos Gold | Cadastral surveys, infrastructure mapping |
| <5 cm (survey-grade RTK) | Trimble R10, Leica GS18 | Legal boundary surveys, construction staking |
Best for Hiking & Outdoor Recreation
The eTrex 32x is the most popular entry-level dedicated GPS device. It supports multi-constellation GNSS (GPS + GLONASS), has a preloaded basemap, and exports tracks and waypoints as GPX. The AA battery design means you can swap batteries in the field. Small, light, and indestructible.
Best value for hikers, trail runners, and recreational GPS users who need a dedicated device rather than relying on a phone.
View on AmazonThe flagship consumer handheld GPS from Garmin. Multi-band GNSS with GPS, GLONASS, Galileo, BeiDou support. Large 3-inch display, preloaded TopoActive maps, wireless data transfer to Garmin Connect. The multi-band GNSS provides noticeably better accuracy in forests and urban canyons than single-band units.
Best overall handheld GPS for serious hikers, hunters, and outdoor professionals who need the best consumer-grade accuracy.
View on AmazonBest for GIS Field Data Collection
The Montana has a large 5-inch glove-friendly touchscreen, making it practical for data collection in field conditions. Supports satellite messaging (inReach), preloaded maps, and wireless data transfer. Accepts external antennas. Popular with utility crews and wildlife biologists.
Best Garmin device for GIS field work — large screen, robust build, satellite comms, and GPX export.
View on AmazonA Bluetooth GPS receiver that connects to your iPhone or iPad. Achieves 1–3 metre accuracy using SBAS (WAAS in North America, EGNOS in Europe). When paired with QField or ArcGIS Field Maps on an iPad, it gives you a large-screen GIS collection setup with better accuracy than a phone alone. Exports GPX and NMEA.
Best choice for GIS professionals who want to use an iPad or iPhone as their field GIS device with improved accuracy.
View on AmazonBest for Fitness & Sports
A compact satellite communicator with GPS tracking. Primary use is two-way satellite messaging and SOS, but it also records tracks exportable as GPX. Pairs with a smartphone for full map display via the Garmin Explore app. If you work in remote areas and need satellite comms alongside GPS tracking, the inReach Mini 2 is the most portable option.
Best for remote field work or expeditions where satellite communication is as important as GPS tracking.
View on AmazonCombines the GPSMAP 67's multi-band GNSS accuracy with inReach satellite communication. Best-in-class battery life for a device with satellite comms. The multi-band receiver provides reliable accuracy under tree cover and in deep valleys where single-band units struggle. Exports tracks and waypoints as GPX.
Best premium all-in-one GPS for serious field professionals who need satellite comms and maximum accuracy.

Every device above exports GPX files — but most GIS workflows need Shapefile, GeoJSON, or GeoPackage. Converting is instant and free:
FAQ
What file format do GPS devices export?
Most consumer GPS devices (Garmin, Suunto, Wahoo) export GPX, which stores tracks, routes, and waypoints as XML. Professional units may also export CSV. Both can be converted to Shapefile, GeoJSON, KML, or GeoPackage using free tools like Maparz.
What accuracy do I need for GIS field data collection?
Consumer GPS (2–5 m) works for ecological surveys, trail mapping, and rough asset inventories. Sub-metre (0.3–1 m) is needed for infrastructure and utility mapping. Centimetre-level RTK GNSS is required for legal surveys and construction.
Can I use my phone for GIS field work?
Smartphones work well for basic collection — QField and Survey123 turn your phone into a capable GIS field device. Accuracy is 3–5 m. For better accuracy, pair with an external Bluetooth GPS receiver like the Bad Elf GPS Pro+.
