The equipment integrates single-shot high-power electric spark source, GPS, high-precision seismograph and geophone It is suitable for single-point reflection method (ie seismic imaging) survey in rivers and lakes The main advantages of equipment are: high excitation energy (up to 30,000 joules), it can quickly analyze and process the collected seismic data, display the reflection time profile in real time in color density map, and reproduce the underground structure
