GSSI 200 HS Antenna Tablet SET

200 HS antenna uses GSSI’s patented HyperStacking technology which improves signal to noise performance and increases the antenna depth penetration under ideal soil conditions. The GS System is suited for geophysical, geotechnical, or environmental applications that require high reliability under challenging survey conditions.



We are selling a demo used GSSI 200 HS Antenna with Panasonic FZ G1 Tough Pad Tablet Complete SET and this 200MHz Digital Antenna gives a depth of penetration up to 21 meters, it is also compatible with SIR 4000 as you can order it separately. This new 200HS antenna serves as the foundation for the GS Series, which is ideal for geophysical, geotechnical, or environmental applications that require high reliability under challenging survey conditions.

Acquire Data Wirelessly:
The HS Module is the communication bridge from the antenna to the controller. With the new WiFi Module, users can use their existing SIR 4000 controller to run the new GS System. The 200 HS improves survey efficiency and in-field use. For multi-person surveys, the WiFi range can reach distances of up to 15 meters (50 feet) within line of sight between the controller and antenna.

HyperStacking Technology & Improved Depth:
The GS System uses GSSI’s proprietary HyperStacking Technology to provide clear, high resolution data of subsurface features. In ideal soil conditions, the 200 HS achieves greater depth penetration, nearly double than that of conventional GPR antenna designs.

Optional Survey Accessories:
Several accessories enhance the ease of use for data collection. These options include a GPS mount and a four-piece wheel kit that can decrease the wear of the antenna on prepared surfaces such as gravel and asphalt. An optional rugged transit case is designed to hold the HS Module, wheel kit, tow strap, batteries, battery charger, and the SIR 4000 WiFi Module or the Panasonic G2.

Panasonic Toughpad G2:
The Panasonic G2 is a rugged Windows 10 tablet that comes with pre-loaded software designed for the GS System. The tablet weighs three pounds (1.4 kg), features an easy to use interface, and has an integrated GIS map mode. The GIS map mode will display the GPR data collected on the left side of the screen and a location map on the right side of the screen. This GIS map mode provides position information using a user-selected GPS and serves as a tool to visualize the survey layout.
