A whole range of small drilling machines exist which can be towed by a car or built on the back of a pick-up, generally in the price range of US$ 5000 – US$ 10.000. Most of these machines are limited to rotary jetting and percussion (in the same way as the percussion gouge). The bigger machines and down-the-hole hammer systems are generally a lot more expensive (>US$ 10.000).
