Nancy's Knit Knacks makes mechanical yarn meters that are based on fishing meter technology. As a rule, these are designed for use by knitters who want to simply measure the length of their yarn. They are not intended for continuous or commercial use. We do not recommend them for use with our skein-winders. They can be used between a swift and a ball winder however.
Generation II tensioned yarn meter
Our latest version of this meter now has an onboard tensioner which helps to increase the accuracy of the meter by helping the user maintain better tension on the yarn.
