The VIY3-300 Ground Penetrating Radar (GPR) is used for location and analysis of the nature of underground objects using electromagnetic pulse radiation, up to 8 meters depth.The VIY3-300 GPR is suitable for searching of both metal and dielectric objects (geological structures, pipes, voids, building constructions etc.).

Basic applications:

• Search for pipes and communication objects;
• Examination of engineering construction (building basement, dams, etc.);
• Investigation of man-caused accident areas;
• Search for subsurface objects (voids, cracks, heterogeneous inclusions);
• Search for underground constructions (tunnels, sewers and etc.);
• Search for sources of leakage from pipelines by indirect signs (excessive moisture).

Features:

• Real time signal pre-processing (Online filtering)
• Automatic-Calibrated online filters
• Wide range of post processing filters
• Increased dynamic range due to digital traces-stacking
• High signal-to-noise ration due to innovative Telbin technology
• Automatic recognition of connected antenna
• Antenna to laptop connection through WiFi or USB
• All GPR components (antennas system, electronic modules, battery, etc.) are assembled in a single case
• No additional Control Unit. Any Windows-based computer (laptop) can be used for working
• Direct connecting of Measuring wheel and GPS to antenna unit
• Antenna unit can be either mounted on the Handcart Cart-36 or towed along the ground by transport belt
• Bidirectional odometer. User can perform sounding in both directions: back and forth
• Low power consumption: not less than 8 hours of working session before next charging
• Sealed lead acid batteries permitted for air-carrying
• Non- inflatable solid wheels of the Handcart
• Durable antenna body made of fiberglass plastic
• Replaceable bottom protector to use antenna without the Handcart
• Each antenna set is ready to use without purchasing any additional accessories
