Quick Scan Check: How do I know if the 3D Ground Scan shows an iron object?
Recognize Metal Objects More Easily in 3D Ground Scans
Ferromagnetic objects typically appear as a paired red and blue signal, representing the positive and negative magnetic poles. When an object lies horizontally in the ground, both poles usually become visible. If a long iron object is positioned vertically, however, only one pole may appear — meaning a red and blue signal next to each other can also indicate two separate vertical objects.
Control scans are essential to verify these signals and improve scanning accuracy. Users are encouraged to use the OKM Visualizer 3D Studio software for deeper insights into interpreting metal detection data. Enjoy watching the short video!
Learn How to Analyze Your Scans in OKM Visualizer 3D Studio
Understanding and interpreting ground scans is one of the most important skills for successful treasure hunting and professional subsurface exploration. With our new video playlist, you’ll get quick and practical insights into scan analysis using OKM’s detection software Visualizer 3D Studio.
All examples shown are real scans from customers around the world. In each video, we guide you through the process of identifying anomalies, interpreting signal patterns, and improving your overall scanning results.
Our goal is to give you the knowledge and confidence to evaluate your own scans. That’s why we share tips, techniques, and best practices directly from our experts — helping you get the most out of your OKM detector.
