Geophysics / RTS COBRA CBD GPR kit

RTS COBRA CBD GPR kit

250/450/800MHz multi-frequency wireless GPR with bandwidth from 50 to 1500 MHz. Complete GPR-kit including Post Processing Software

The RTS COBRA CBD GPR kit is an advanced ground-penetrating radar system designed for real-time wireless geophysical data acquisition. It includes a COBRA CBD Wireless GPR antenna, post-processing software, and offers operating frequencies of 250, 450, and 800 MHz, with an operating band ranging from 50 to 1500 MHz.

This wide frequency range allows adaptation to various subsurface conditions, providing high spatial resolution and adequate penetration. The system is designed to collect hundreds of thousands of pulse reflections per second, facilitating the identification of underground objects.
