COMPARISON CHARTS

WEIGHTS AND LENGTHS
Many lures come from the U.S.A. where Imperial measures are still used, but some lures are European in origin and so come labelled up with metric sizes. Rather than convert them I leave them as they are. This dual approach does not confuse me, but it might do you. So here is a rough and ready conversion chart.

LINE DIAMETERS

This chart is a guideline to what you can expect from nylon monofilament. It will also allow you to compare other types of lines (copolymers or braids) with monofilament by their diameters.
