How to Use the Magnetometer Mode | OKM eXp 7000 Tutorial

November 05, 2025

In this tutorial, we demonstrate how to work with the Magnetometer Mode of the OKM eXp 7000 Professional Plus.

Magnetometer Mode is specifically designed to identify and remove near-surface ferrous objects such as nails, cans, and screws. Clearing these items before a 3D Ground Scan helps reduce interference and significantly improves scan accuracy.

What You’ll Learn in This Tutorial

Purpose of Magnetometer Mode: Understand when and why this mode should be used before conducting a 3D Ground Scan.
Preparing the Scan Area: Learn how to systematically scan the surface to locate small iron objects.
Identifying Ferrous Targets: See how typical surface-level interference appears during magnetometer detection.
Cleaning the Area Effectively: Remove disturbing targets to prevent false signals in later scans.
Optimizing 3D Scan Results: Improve the quality and reliability of your 3D Ground Scan by starting with a clean field.

Using Magnetometer Mode as a preparatory step is a best practice for professional scanning. This tutorial shows how a short, structured surface check can save time, reduce noise, and lead to significantly clearer 3D scan results.
