Write a Review

The Tero Vido Expander 3D System is a compact measuring device for the localization of metals and cavities below the earth's surface.

With the Expander Gold and the supplied software, both magnetic metals such as iron or steel and non-magnetic precious metals such as gold, silver, copper or bronze can be found. This 3D floor scanner can also be used to locate cavities such as tombs, graves, tunnels and bunkers.

Depending on the size of the target and the nature of the ground, the expander can be used Tero Vido Achieve depths of up to 15m.

The multilingual user interface of the Tero Vido 3D software is available in several languages ​​(eg German, English, French, Arabic, Turkish, and many more). Free and automatic software updates will include improvements as well as other languages.
