1. A device or instrument used to investigate subsurface soil and rock conditions, typically by drilling or penetrating the ground to collect samples or data.
Usage: technical; geology/civil engineering

Examples

• The geoprobe was used to collect soil samples at various depths across the construction site.
• Engineers deployed a geoprobe to assess ground stability before building the foundation.
• The geoprobe revealed layers of clay and sand beneath the surface.
• Geoprobe technology allows geologists to study subsurface conditions without extensive excavation.
