Who Makes the Best Drill Rig in the World?

Who do you think makes the best rigs in the world? 

The Geotechnical Drilling Industry is a funny one. It’s small, tight knit, and not many people other than those in it know what geotechnical drilling even is. In fact, most of the time random people walk by a geotechnical driller at work, they’ll ask the common phrase “Are you digging for gold?” While geotechnical drilling methods and strategies may change from country to country – there’s one thing almost all drillers enjoy – looking at new and beautiful rigs.
