Frequently Asked Questions
Standard smartphone GPS is only accurate to 5–16 feet. The Emlid Reach RX achieves centimeter-level accuracy (1–3 cm)—essential for knowing exactly where your buried assets are located. The kit connects to your iPhone via Bluetooth and works seamlessly with our app. No surveying experience required.
Currently, HAL Asset Locator integrates exclusively with the Emlid Reach RX. We chose this approach to ensure the app remains simple and reliable, even for users with no geolocation experience. We plan to add support for additional devices in the future.
The app requires an iPhone with LiDAR. Supported models:
- iPhone 12 Pro / Pro Max
- iPhone 13 Pro / Pro Max
- iPhone 14 Pro / Pro Max
- iPhone 15 Pro / Pro Max
- iPhone 16 Pro / Pro Max
- iPhone 17 Pro / Pro Max
