Rugged, Wireless Low Frequency 200 MHz GPR System
GSSI introduces the GS Series, our next-generation family of high-performance antennas targeting applications that require deeper penetration depths. The first antenna in the series is the 200 HS. This digital, wireless antenna features a 200 MHz center frequency and employs GSSI’s proprietary HyperStacking® technology. This technology improves signal to noise performance and increases depth penetration under all soil conditions. The GS Series is ideal for geophysical, geotechnical, and environmental applications that require high reliability under challenging survey conditions.
