Cleaner satellite data
Compared with a phone alone, the receiver is designed to improve signal quality and make field contour logging more stable while walking or driving around the boundary.
Area measurement GNSS receiver
GM SPIKE 2 for accurate field area measurement
A compact Bluetooth GNSS receiver designed for farmers, agronomists and land measurement tasks where you need a cleaner signal, faster satellite lock and more reliable boundary recording than a phone or tablet alone.
Optimized for agricultural field measurement. If your project requires stakeout or cadastral-grade accuracy, explore our GNSS RTK receiver series.
Why GM SPIKE 2
GM SPIKE 2 is a practical measurement tool for agricultural field boundaries. It improves real-world positioning on Android devices by using a dedicated external GNSS receiver with a stronger antenna environment, cleaner signal handling and more stable continuous point logging along the field edge.
Works from vehicle or on foot
Mount it on a vehicle roof with the magnetic holder or fix it on a telescopic pole for walking measurements in narrow, irregular or obstacle-rich areas.
Android + geometer SCOUT
Connect by Bluetooth, open geometer SCOUT and start measuring areas, points, distances, polygons and field boundaries in one familiar workflow.
How it works in the field
Simple workflow, fast onboarding and reliable results for routine agricultural measurements.
Connect over Bluetooth
Pair GM SPIKE 2 with your Android phone or tablet and place the receiver on a vehicle roof or on a pole for walking measurement.
Open geometer SCOUT
Launch the app, create a project, select the map type you need and start field measurement using the external receiver as the location source.
Walk or drive along the border
Record the real field shape in continuous mode to capture bends, turns and irregular edges more accurately than rough tap-on-map estimation.
Save, edit and export
Review the polygon, split zones if needed, add notes and export the result for reporting, planning or transfer to other systems.
Best fit tasks
- Field area measurement
- Boundary recording for agricultural fields
- Measuring irregular contours and inner exclusions
- Distance and point measurement
- Project storage and KML workflow
Built for daily field work
New housing, compact dimensions and better energy efficiency make the second generation easier to carry, easier to mount and more practical for long sessions in the field.
- GNSS indicator
- Battery status indicator
- Bluetooth status indicator
geometer SCOUT software
The system is powered by geometer SCOUT for Android — a mobile field measurement app that helps you measure, edit, organize and export map objects directly from your smartphone or tablet.
Measure points, lines and areas
Work with coordinates, distances and polygons in one project. Use tap-on-map measurement or connect an internal or external GNSS source.
Edit and manage objects
Rename objects, add notes, adjust points, change fill color, control visibility and keep field information organized in layers.
Advanced geometry tools
Split plots, add holes, build circular shapes, measure between objects and refine the final map directly in the field.
Coordinate tools
Enter your own coordinates, average location to improve accuracy and use the point navigation function when you need to move to a selected place.
Flexible map views
Switch between standard, satellite, topographic and grid-style views depending on the task, terrain and visibility conditions.
KML import and export
Transfer projects between systems, save completed measurements and continue your workflow in office software or other mapping environments.
Benefits for farmers and agronomists
The value of GM SPIKE 2 is not just better positioning. It helps make day-to-day agricultural measurement faster, more repeatable and easier to document.
Measure real field shape
Capture bends, irregular borders, narrow entries and curved edges with continuous logging instead of rough visual estimation.
Reduce manual errors
Dedicated external GNSS positioning gives more dependable geometry than relying only on a consumer phone in the field.
Work from a car or on foot
Choose the faster vehicle workflow for accessible edges or switch to the pole setup for tight spaces and complex boundaries.
Keep digital field records
Store measured plots, export files, add notes and keep consistent data for future planning and comparison.
