actualy it is not a myth at all, over the years there have been several colections doen and the swing arms only have a 25% accuracy rater from new.

also because of the way they are used they have a tendency to go farther out over time.

out of the 6 swing arms I have only 2 were accurate, I threw the rest out and use the 2 for quick checks and store them with ro water to prevent salt from changing the accuracy.
