The LargeRotoSonic hosts the LS 50K, with simultaneous vibration and rotation, so the full Sonic force is utilized which enables you to reach greater depths. This rig is state of the art technology and designed to face the most challenging project conditions in the world. 

When implementing the LRS you have larger drill pipes at your disposal. Also, it is possible to take larger diameter high quality samples at a higher rate per day. All aspects that make the LRS suited for a variety of special projects. From Geotechnical drilling to Sonic sampling for mining and mineral exploration, the LRS makes the difference.

With safety features as the Fully automated rod or casing handler and triple floatable clamp the LRS also provides a safe and ergonomic working method. See specification sheet for more safety features.
