%X one of the seismic energy sources most frequently used for shallow seismic data acquisition is the sledgehammer. however, the seismic pulse generated by the sledgehammer is not repeatable, it depends on the operating style of the person to use the sledgehammer. for a relative improvement in terms of increased penetration of waves elastic in the ground, to increase the signal - noise ratio, higher resolution vertical, the more impact energy, higher frequency content, and fewer of shots per site, the study reported here shows the design, building and testing of a device named gis (generador de impacto s¨ªsmico). device testing was conducted by comparing the results obtained on the same seismic line with the gis and the sledgehammer. it was concluded that seismic data obtained with the gis provide higher resolution and research depth than that obtained with the sledgehammer, as the signal amplitude, signal - noise, penetration of acoustic waves in the subsoil and number of reflectors displayed was greater.
