How To Use Offline Maps for Hunting
Offline maps let you view detailed hunting maps, see your GPS location, mark Waypoints, and record tracks when you have little or no cell service. To use them effectively, download your entire hunt area before leaving service, overlap adjacent maps to prevent gaps, test the download in Airplane Mode, and carry backup power and navigation tools.
Key Takeaways
- Download Offline Maps before every hunt, even if you expect cell coverage.
- Save your hunting area, access routes, trailheads, camp, parking locations, adjacent terrain, and potential recovery routes.
- Overlap neighboring map downloads so you do not accidentally walk or drive beyond your saved coverage.
- Choose high resolution for small areas where terrain detail matters and medium or low resolution for broader coverage.
- Test every saved map in Airplane Mode before leaving home.
- Mark your vehicle before walking away, record a track, and save Waypoints for sign, access, water, glassing locations, and other useful observations.
- Offline maps are a navigation aid—not a substitute for current regulations, posted signs, sound judgment, or a backup compass and map.
What Are Offline Hunting Maps?
Offline hunting maps are map files saved directly to a phone or tablet for use without an internet or cellular connection. Because a phone’s GPS receiver can determine location without cell service, a downloaded map can continue showing the hunter’s position in remote terrain.
With onX Hunt Offline Maps, hunters can access saved Basemap areas, compatible Map Layers, Map Markups, and GPS location information inside the downloaded area. This makes it possible to study terrain, monitor proximity to land boundaries, mark locations, and track travel after cell coverage disappears.
The distinction is simple:
- GPS determines where you are.
- The downloaded map shows what is around you.
- Cell service is not required for either function once the map data is stored on your device.
However, features that depend on new internet data—such as current weather conditions—will not update while the device is offline.
How To Download Offline Maps in onX Hunt
Follow these steps while connected to reliable Wi-Fi or cellular service:
- Open the Hunt App and tap Offline Maps in the bottom toolbar.
- Tap New Offline Map.
- Position the map over the area you want to save.
- Select Low, Medium, or High resolution.
- Name the map and tap Save.
- Wait for the download to finish.
- Confirm that a green checkmark appears beside the saved map.
- Test the map by putting your device in Airplane Mode.
The green checkmark confirms that the map has been downloaded to that device. Although saved Offline Maps appear in your account across connected devices, the actual download is device-specific. If you create a map on a computer, you still need to download it to the phone or tablet you will carry.
For a visual walkthrough, see the onX Hunt Offline Maps tutorial.
How Much Area Should You Download?
Download every place you could reasonably enter during the hunt—not only the location where you expect to find an animal.
Your saved coverage should include:
- The entire hunting area or unit.
- Roads and trails leading to the area.
- Your trailhead, parking location, and camp.
- Alternate access routes.
- Adjacent ridges and drainages.
- Backup hunting locations.
- Potential routes for tracking or recovering an animal.
- The route back to reliable service.
When several Offline Maps are needed, arrange them in a grid and overlap their edges slightly. Overlapping downloads help prevent narrow strips of missing map data between saved areas.
A useful setup is to save a broad area at Low or Medium resolution, then place smaller High-resolution maps over the locations where you expect to hunt on foot. This provides wide coverage without giving up detailed terrain information in your priority areas.
Which Offline Map Resolution Should You Choose When Downloading Offline Maps?
onX Hunt offers three download resolutions:
| Resolution | Best For | Tradeoff |
| Low | Large regions, long access routes, and broad backup coverage | Covers more ground with less Basemap detail |
| Medium | Hunting units and general scouting areas | Balances coverage, detail, and storage |
| High | Small hunt areas, detailed terrain analysis, and precise navigation | Covers less area and uses more storage |
High resolution provides the same level of Basemap detail available online, but it creates a larger file size for a smaller area. The best choice depends on the size of the hunt area, the available storage on your device, and how closely you need to examine terrain.
The number of Offline Maps you can save is limited by your device’s available storage.
What Information Is Saved in an Offline Map?
An onX Hunt Offline Map stores the Basemap and offline-compatible Map Layer data within the saved boundary. You do not need to turn on each compatible layer before downloading it. Once offline, you can toggle saved layers on and off as needed.
Useful hunting layers may include:
- Public and private land boundaries.
- Landowner and parcel information.
- Hunting unit or game management unit boundaries.
- Motorized roads and trails.
- Walk-in or possible-access areas.
- Historic wildfire information.
- State-specific hunting and habitat data.
Layer availability depends on the location and membership level.
Satellite, Topo, and Hybrid Basemaps can be saved for offline use, and you can view in 2D or 3D offline.
How To Test Offline Maps Before a Hunt
Never assume a completed-looking download will work when you lose service. Test it first.
Before leaving home:
- Confirm that the Hunt App and your downloaded maps are updated.
- Put the phone in Airplane Mode.
- Open onX Hunt and tap Offline Maps.
- Pan across the entire saved area.
- Zoom in and out at several locations.
- Toggle important Map Layers.
- Confirm that your current GPS position appears.
- Inspect the edges where adjacent maps meet.
- Verify that your access road, parking area, camp, and backup locations are covered.
If anything is missing, reconnect to service and save or update the affected area.
Also check your phone’s available storage, location permissions, and battery condition. A downloaded map cannot help if location access is disabled or the device runs out of power.
How To Use Offline Maps While Hunting
1. Enter Offline Mode
When service becomes unreliable, make the switch to Airplane Mode. This tells the Hunt App to use the map data stored on your device and helps save battery. Your phone can still receive GPS signals in Airplane Mode, although exact device settings can vary.
2. Mark Your Vehicle Before You Leave
Drop a Waypoint at your truck, trailhead, boat landing, camp, or other return point before beginning the hunt.
Do this while standing at the location rather than trying to reconstruct it later. Consider adding a short note such as the date, gate status, access conditions, or vehicle description when hunting with a group.
3. Start Go & Track
Start a Track as you leave your vehicle or camp. The recorded line creates a breadcrumb trail of your route.
A Track can help you:
- Retrace your path through timber or darkness.
- Avoid unintentionally covering the same ground twice.
- Estimate travel distance.
- Compare access routes.
- Document scouting coverage.
- Review successful approaches after the hunt.
Tracking your route does not eliminate the need to stay oriented. Check your map at decision points instead of waiting until you are disoriented.
4. Save Useful Waypoints
Mark information that will matter later, including:
- Tracks, beds, rubs, scrapes, or wallows.
- Feeding and bedding areas.
- Water sources.
- Glassing positions.
- Trail junctions and creek crossings.
- Gates and access restrictions.
- Campsites.
- Stand or blind locations.
- Harvest or recovery locations.
- Hazards such as cliffs, difficult crossings, or deadfall.
Use consistent colors, icons, names, and notes. “Fresh elk rubs—north-facing timber—Aug. 21” will be more useful next season than a pin labeled “Spot 1.”
Waypoints and Tracks created offline remain available on the device and can sync with your account after connectivity returns.
5. Use Terrain To Plan Your Approach
When you locate an animal, use the Topo or Hybrid Basemap to evaluate the ground between you and the target.
Look for:
- Ridges and terrain folds that conceal movement.
- Saddles and benches that may concentrate travel.
- Steep slopes or cliffs that could block an approach.
- Creeks, marshes, and other obstacles.
- Roads or trails that offer a practical recovery route.
- Public-private boundaries that affect where you can travel or hunt.
Combine the map with what you can see, the current wind, and actual ground conditions. A route that appears possible on a map may be unsafe or impassable in person.
6. Monitor Boundaries Carefully
Offline property and unit layers help hunters maintain awareness when signs, fences, or terrain features are unclear. They are particularly useful in checkerboard ownership, near narrow public parcels, and where a hunting-unit boundary follows a ridge or drainage.
However, map boundaries are not legal surveys. Parcel information can vary with the quality and timing of county records, and GPS accuracy depends on the device and conditions. Always respect posted signs and closures, verify regulations with the appropriate agency, and leave a margin of safety around uncertain boundaries. Only a licensed surveyor can establish an official property line.
How To Preserve Phone Battery in the Field
Battery management is part of offline navigation. Use these practices during long days or multi-day hunts:
- Turn on Airplane Mode when you do not need cellular service.
- Reduce screen brightness.
- Lock the screen between map checks.
- Close unnecessary background apps.
- Use Low Power Mode or Battery Saver.
- Keep the phone warm in cold conditions.
- Carry a charged power bank and cable.
- Protect charging ports from moisture and debris.
- Test your phone and battery pack before the trip.
Cold weather can temporarily reduce battery performance. Carrying the phone and power bank in an inside pocket can help keep them warm.
What Works Without Cell Service?
| Feature | Available Offline? |
| View downloaded Basemaps | Yes |
| View compatible downloaded Map Layers | Yes |
| See your GPS position | Yes |
| Create Waypoints and Map Markups | Yes |
| Record a Track | Yes |
| Toggle saved layers | Yes |
| View 3D Maps | Yes |
| Receive updated weather and wind data | No |
| Stream map data outside the downloaded area | No |
| Sync new information across devices | Not until connectivity returns |
Because weather data requires an internet connection, check the latest forecast before leaving service. Record important wind shifts, precipitation timing, temperature changes, and severe-weather risks somewhere accessible offline.
Common Offline Map Mistakes
Downloading Too Small an Area
An animal, closed road, recovery effort, or change of plans can pull you beyond your original hunt zone. Save broad backup coverage and include every access route.
Leaving Gaps Between Downloads
Maps placed edge to edge can leave uncovered strips. Overlap adjacent downloads slightly.
Forgetting the Device-Specific Download
A map created on a desktop may appear in the mobile app without being stored on the phone. Confirm the green checkmark on the device you will carry.
Skipping the Airplane Mode Test
A map may appear to work because the phone is still loading data over Wi-Fi or cellular service. Airplane Mode provides a realistic test.
Relying on Online-Only Features
Updated weather and other “Current Conditions” layers require connectivity. Use them during planning, then save the information you will need in the field.
Failing To Update Old Maps
Review saved maps before each trip. If the App shows that an update is available, update the download before leaving service.
Treating a Phone as the Only Safety Tool
Electronics can fail, break, get wet, or lose power. Carry a compass and suitable backup map, and know how to use them. For remote trips, consider an appropriate satellite communication device and leave a trip plan with someone you trust.
