The Crossover 4080 GPR is a powerful tool designed for underground surveys, ideal for detecting pipes, voids, road structures, and foundations—all in one system. With its Dual Frequency system (400 MHz / 800 MHz), it provides both deep subsurface profiles and high-resolution shallow imaging simultaneously.

Key Features

• 400 MHz Frequency: Suitable for deep subsurface scanning such as road structures or large voids. Offers excellent penetration in less complex ground conditions.
• 800 MHz Frequency: Provides higher resolution for shallow areas—ideal for detecting pipes and smaller objects near the surface.
• Dual-Frequency Operation (400 + 800 MHz): Delivers comprehensive data in one scan, improving risk analysis accuracy, such as detecting voids beneath roads.
• Built-in GPS and wireless data recording for precise and efficient field operations.
