Both models are solid 2-piece construction with a partitioned spool to reduce line tangles and come pre-loaded with 20 ft. of .095" Cross-Fire trimmer line. The ECHOmatic heads require manual loading of trimmer line. Commercial landscapers can load multiple heads for field use and save downtime in the field by just replacing the head with pre-loaded heads.  A great option for busy days where every second counts.
