**COMACCHIO GEO 501** is a drilling rig for water well and geothermal work. In down-the-hole drilling, impact energy is generated directly at the bottom of the borehole. The head, casing and flushing arrangement are selected for the drilling method and ground conditions.

The GEO 501 develops the Scandinavian DTH concept with higher installed power. Its oscillating undercarriage and mast arrangement support tool handling across changing sites.
