Record exact pipe locations and depth during installation. Know exactly where to dig years later.
Cloud-based software for mapping and documenting underground infrastructure. Capture, visualize, and manage geo-referenced data with sub-inch accuracy.
The Emlid Reach RX is a compact, handheld GNSS receiver that delivers sub-inch positioning accuracy. It connects wirelessly to your iPhone via Bluetooth and receives signals from multiple satellite constellations.
You'll also need an iPhone with LiDAR technology, available on iPhone 13 Pro and Pro Max, and new Pro and Pro Max models. LiDAR allows the app to capture depth and spatial data accurately for precise asset positioning.

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.
