The unique design of the Watson ExcaDrill permits site access advantages otherwise unattainable with most conventional construction drilling equipment. It features low overhead clearance, mobility, drilling on gradient slope conditions, drilling on variable elevations, reaching over barriers or around obstacles, larger tool clearance and minimal ground disturbance. Mounting to the boom of a conventional excavator allows for a long reach advantage over barriers or obstacles.  The high mobility of the excavator gets the drill on site regardless of sloping or uneven terrain conditions. Four mast height options ranging from 18-25 feet are designed to reach required drill depths while under low clearance, height restricted structures or wires.
