Boart Longyear is planning an impressive presence at the show bringing its highly productive LS™250 sonic drill rig to be displayed in booth number 763. The company was the first U.S. firm to utilize sonic equipment for environmental drilling with this technology now being used in a wide variety of soft ground and shallow drilling applications. Sonic drilling is shown to be faster, with less than one percent drill deviation, and is more accurate than conventional overburden drilling. It also creates more efficient penetration, reducing waste up to 80% and resulting in maximum core recovery.
