just to add, you can drill easily a 100m deep borehole with a tri-pot, drill pipes and a 75m3/hr (HONDA) mud pump...@10". just need to know how to do it. The percussion drilling is only limited to mast-hookload and the cable length...and its capacity (not really important if 65m already on the drum...)...100m rotary drilling is 1 to 2days max...
