🛠️ New or Used? What Surveyors Need to Know
If you’re on a tight budget, buying a used GNSS receiver is a smart option — but always check for:
- 📅 License status (RTK/NTRIP enabled?)
- 🔋 Battery health
- 📦 Included accessories (pole, charger, controller)
Many surveyors are turning to modern budget-friendly brands like CHCNAV, Emlid, and Tersus which offer solid performance at half the cost of legacy brands.
🔌 Compatibility with Android Survey Apps
Make sure your receiver can connect via Bluetooth or USB OTG to your Android device. Most models in 2025 support:
- SW Maps
- Field Genius for Android
- SurvX / SurPad
New GNSS buyers should also check if the receiver can function as both a base and rover, in case you plan to build your own RTK network.
🎯 Final Thoughts: Choose Based on Your Workflow
There’s no “best” GNSS receiver for everyone. Consider:
- 🛠️ Your level of experience
- 🌍 The region you survey in
- 📶 Internet or radio availability
- 💵 Budget for initial investment and licenses
Whether you go for a high-end Leica or a budget-friendly Emlid, make sure the receiver supports your workflow — and is backed by helpful support.
