The carriage headrig has continued to evolve with the industry.  From manually operated to photocell arrays to front side only shape scanning.  Today the gold standard is complete coverage 3D scanning. JoeScan's complete coverage 3D scanning is based on our standard JS-20 scanners, known for their simplicity, flexibility and reliability.

By scanning both the front and back side of every log, our scanners provide the optimizer with a complete picture of the possible value of every log. The optimizer can then select a cut that maximizes that value. 

The dual-laser JS-20DL offers a careful balance between cost and flexibility. Dual-laser units can be individually placed and oriented to ensure every laser is getting a good scan, avoiding the many obstructions present in a mill environment.
