Impact Driven

Impact-driven air scribes are the most powerful in the fossil preparation world. They use compressed air to drive a piston to repeatedly strike the anvil at the top of the stylus. This occurs many thousands of times per minute. For more information on how these powerful air pens work, please read this article.


We have two impact-driven air pens in our range. The modified CP-9361, the ZOIC Chicago and our own design, low-pressure ZPT-TR, The T Rex.
