Maysville, Ky. — Carlson Software unveiled the new C-ALS Gyro as part of its Laser Measurement Devices (LMD) product division at the 2019 SME Annual Conference and Expo. The new Carlson Cavity Auto-Scanning Laser System (C-ALS) Gyro gives greater navigational capability, ensuring that the probe’s position along the borehole can be determined without relying on the mechanical alignment of deployment rods or a magnetic compass. The Gyro unit contains a 3-axis gyro which monitors the probes heading and accelerometers which determine the inclination, allowing it to be deployed downwards, upwards, or in a horizontal hole. The data recorded provides the production team with information needed to optimize and monitor the operation.

The C-ALS provides safe, quick, and reliable mapping capabilities for inaccessible underground cavities. The system is deployable via boreholes on cable or rods, via a boom, or on a zip-wire, the C-ALS system can be used from the surface to provide a detailed visual record of the subsurface environment in a wide range of applications.

The LMD product division was previously Renishaw SMD. Carlson Software acquired the products and supporting staff through a 2017 acquisition. The LMD division includes the Cabled Boretrak, Rodded Boretrak, Quarryman Pro, Merlin, C-ALS, and Void Scanner.
